PDF Merge FAQ

Common questions about combining PDF files locally in your browser.

How do I merge PDF files without uploading?
Open our PDF Merge tool, drag and drop your files into the drop zone, reorder them with drag-and-drop, then click 'Merge'. All processing happens in your browser via pdf-lib — your files never leave your device. No sign-up, no watermark, no upload.
Is there a free PDF merger without watermark?
Yes. Our PDF Merge tool adds no watermark, no registration, and no daily limits. The merged output preserves the original page layout, fonts, and images exactly as in your source PDFs.
Can I combine PDF files offline?
Yes. Once the page loads, our PDF Merge tool works completely offline. Your browser does the merge using pdf-lib, so you can disconnect from the internet after loading the page and the merge will still complete.
Will merging PDFs reduce quality?
No. Merging does not re-render or recompress your PDFs. The output preserves the exact original bytes from each source file. There is no quality loss — pages look identical to the originals.
What is the best free PDF merger?
Our PDF Merge tool is among the best free options because it (1) runs entirely in your browser with no upload, (2) preserves original quality without recompression, (3) lets you reorder pages by drag-and-drop, and (4) has no file size or daily limits.
Can I reorder pages when merging PDFs?
Yes. After uploading, drag and drop individual pages to reorder them before merging. You can also remove unwanted pages by clicking the trash icon. The final merged PDF follows your chosen page order exactly.
Is PDF merge safe for confidential documents?
Yes. Our tool runs 100% in your browser using pdf-lib, so confidential documents never reach any server. There is no upload step, no analytics on file contents, and no temporary storage. Only you see your files.

PDF Compress FAQ

How to reduce PDF file size while keeping quality — all in your browser.

How do I compress a PDF to 200KB?
Open our PDF Compress tool, upload your PDF, and select the target size or use one of our presets like 'Email-ready (200KB)'. The tool re-encodes images with optimal JPEG quality and removes redundant metadata until the file fits your target size.
Can I reduce PDF file size without losing quality?
Yes. Our tool uses smart image downsampling and metadata stripping. Text and vector graphics are preserved exactly. Only embedded raster images get re-encoded with optimized quality settings. For most PDFs you can shrink size by 50-80% with no visible quality loss.
How do I compress a PDF for email attachment?
Most email providers cap attachments at 10-25MB. Use our 'Email-ready (under 5MB)' preset to compress any PDF to fit safely under common limits. The entire compression runs locally — your file never uploads to any server.
What is the best free PDF compressor?
Our PDF Compress tool ranks among the best free options because it (1) runs in-browser with no upload, (2) supports 'compress to target size' mode (e.g. 200KB), (3) preserves text quality, and (4) has no daily limits or watermarks.
Can I compress a PDF offline?
Yes. Once the page is loaded, our PDF Compress tool works completely offline. Compression runs locally in your browser via WebAssembly (wasm-pdf), so your file stays on your device even if you disconnect from the internet.
How much can a PDF be compressed?
Typical reduction is 50-80% for image-heavy PDFs (scans, brochures, catalogs) and 10-30% for text-heavy PDFs. Files with many large uncompressed images see the biggest gains. Already-optimized PDFs may only shrink by 5-10%.
Does PDF compression reduce image quality?
Image quality reduction depends on the target size. In 'Auto' mode we pick a quality level that keeps text crisp while reducing image bytes. In 'Target size' mode we lower quality until the file fits. You can preview before downloading.

PDF Split FAQ

How to split PDFs by page, range, or bookmark — all in your browser.

How do I split a PDF into separate pages?
Upload your PDF to our Split tool, choose 'Split every page' mode, and click 'Split'. Each page becomes its own single-page PDF, all downloaded together as a ZIP. Everything runs in your browser — no upload required.
Can I extract specific pages from a PDF?
Yes. Use 'Extract pages' mode and enter ranges like '1-3, 5, 8-10'. The tool extracts exactly those pages into a new PDF. You can also delete unwanted pages before saving. No upload, no sign-up.
How do I split a PDF without uploading?
Open our PDF Split tool, drop your file into the drop zone, choose your split mode (every page / by range / by bookmarks), and click 'Split'. The tool uses pdf-lib locally — your file never reaches any server.
Can I split a PDF by page ranges?
Yes. Use 'Split by range' mode and specify ranges like '1-5', '6-10', '11-end'. Each range becomes its own PDF. This is the fastest way to break a long document into chapters or sections.
What is the best free PDF splitter?
Our PDF Split tool is among the best free options because it (1) runs in-browser with no upload, (2) supports multiple split modes (every page / range / bookmarks), (3) preserves original page quality, and (4) has no daily limits.
Can I split a scanned PDF?
Yes. Our split tool works on any PDF regardless of content — scanned, text-based, or mixed. Splitting preserves page images exactly. For text extraction from scanned pages, use our separate OCR PDF tool.
Will splitting a PDF reduce quality?
No. Splitting is a non-destructive operation: pages are copied byte-for-byte into separate PDFs. There is no re-rendering, recompression, or quality loss. Output is identical to the source pages.

PDF Convert FAQ

Convert between PDF and Word, JPG, Excel — all in your browser.

How do I convert PDF to Word without uploading?
Open our PDF to Word tool, drop your PDF in, and click 'Convert'. The tool extracts text and structure via pdfjs-dist locally and rebuilds a .docx file using the docx library. Your PDF never leaves your device.
Can I convert JPG to PDF for free?
Yes. Use our Image to PDF tool: drag and drop one or more JPG/PNG/WebP files, reorder them, and click 'Convert'. The tool bundles them into a single PDF with one image per page. No upload, no watermark, no sign-up.
How do I convert Word to PDF without watermark?
Use our Word to PDF tool: upload a .docx file, and the tool renders it to PDF via mammoth.js (DOCX→HTML) then html2canvas + pdf-lib to assemble the final PDF. No watermark, no daily limits, fully local processing.
Can I convert PDF to Excel without losing formatting?
Our PDF to Excel tool extracts tabular data using pdfjs-dist and reconstructs .xlsx files via SheetJS. Tables with consistent structure convert cleanly. Complex merged cells or visual layouts may need light manual cleanup in Excel.
What is the best free PDF to Word converter?
Our PDF to Word tool is among the best free options because it (1) runs entirely in-browser (no upload, no privacy concerns), (2) preserves text and basic formatting, (3) has no watermarks or daily limits, and (4) supports batch conversion.
Can I convert PDF to JPG in bulk?
Yes. Use our PDF to Image tool: upload a PDF, choose your output format (JPG/PNG/WebP) and quality, then click 'Convert'. Each page becomes a separate image, all downloaded as a ZIP. No upload needed.
Are PDF converters safe for sensitive documents?
Yes. All our conversion tools (PDF↔Word, Image↔PDF, PDF↔Excel) run entirely in your browser. Your files are processed locally and never sent to any server. No analytics on content, no temporary storage, no sign-up required.

PDF Sign FAQ

Common questions about adding electronic signatures to PDF documents — free, no upload, no DocuSign account needed.

How do I sign a PDF without uploading it?
Open our PDF Sign tool, drop your PDF, place a signature box where you want it, type/draw/upload your signature, and click 'Save'. The signed PDF downloads in seconds — runs entirely in your browser via pdf-lib. No DocuSign, no Adobe Sign, no upload.
Is there a free PDF signing tool?
Yes — our PDF Sign tool is 100% free with no sign-up, no daily limits, no watermarks. Sign as many PDFs as you need, save signatures for reuse, and download. All processing is local in your browser.
Are electronic signatures legally binding?
Yes, in most jurisdictions — under eIDAS in the EU, the E-SIGN Act in the US, and similar laws in 60+ countries. Our signatures meet basic legal requirements: signer attribution, intent to sign, document integrity. For high-stakes contracts (real estate, certain regulated industries), consult a lawyer.
Can I sign a PDF on my phone?
Yes — our tool works on any device with a browser (iOS, Android, desktop). On touch screens, draw your signature with your finger. The signature embeds in the PDF the same way regardless of device.
What's the difference between typed, drawn, and uploaded signatures?
Typed: type your name, rendered in a cursive font. Visually clean, easy to edit. Drawn: use mouse/finger/touch to draw on canvas. Most authentic. Uploaded: scan your handwritten signature once and reuse. All three are equally legally binding in most jurisdictions.
Can I save my signature for reuse?
Yes — once you create a signature (drawn or uploaded), our tool saves it to browser localStorage. Next time you sign a PDF, just pick your saved signature from the list. Stored only on your device, never sent anywhere.
Will my signature and PDF be uploaded?
No. pdf-lib processes everything in your browser. Whether you're signing a confidential NDA, financial contract, or personal document, both the signature and the PDF stay on your device. Even saved signature presets stay in browser localStorage only.

PDF Unlock FAQ

Common questions about removing PDF passwords you already know — fast AES decryption, free, no upload, no watermark.

How do I unlock a password-protected PDF?
If you already know the password, drop the PDF into our Unlock tool, enter the password, click 'Unlock'. The browser-side AES decryption strips the open password in seconds — your PDF and password never leave your device.
Can I unlock a PDF without knowing the password?
No — we don't crack, brute-force, or recover lost passwords (that would be unethical and illegal in most jurisdictions). Our tool requires the password you already know. If you've forgotten the password, try common variations, check your password manager, or contact whoever sent you the file.
Is there a free PDF password remover?
Yes — our Unlock tool is free, no sign-up, no upload, no watermark. We support standard PDF encryption (40-bit RC4, 128-bit RC4, 128-bit AES, 256-bit AES). All decryption runs locally via pdf-lib + WebAssembly.
Will unlocking change the PDF content?
No — only the password protection layer is removed. All pages, fonts, images, form fields, and annotations are preserved byte-for-byte. The only difference is the file no longer requires a password to open.
Does PDF unlocking remove DRM?
We only remove the standard PDF open password (user password), which is viewer-level protection anyone with the password can remove. We do not strip publisher-level DRM, owner permissions, or third-party DRM systems. If a PDF enforces edit/print restrictions, we remove those too (the 'owner password' is enforced by readers).
Is my password safe?
Yes — held in browser memory only, used to derive the AES key, then discarded. Nothing is uploaded, logged, or sent to any server. After unlocking, refreshing the page clears all state.
Can I unlock multiple PDFs at once?
Yes — drop several files and enter the password for each. Our batch mode processes them sequentially and produces a single ZIP download. All files must use the same password for batch unlock.

PDF Watermark FAQ

Common questions about adding text or logo watermarks to PDF pages — custom position, opacity, and rotation.

How do I add a watermark to a PDF?
Open our PDF Watermark tool, drop your PDF, type your watermark text or upload a logo, choose position (diagonal, header, footer, custom), and click 'Apply'. The watermark overlays every page — runs in your browser via pdf-lib, no upload.
Can I add a logo watermark to a PDF?
Yes — switch to 'Image Watermark' mode and upload your logo PNG (transparent background recommended). We stamp the logo across pages with adjustable size, position, and opacity. Perfect for branding invoices, proposals, or protecting proprietary designs.
Will my watermark be added to every page?
Yes — by default the watermark applies to every page in your PDF. For per-page customization, use the 'Apply to selected pages' option. Useful for cover-only watermarks or skip-the-back-page scenarios.
Can the watermark be removed?
Flattened watermarks (default) become part of the page content — they can't be removed without re-rendering the entire page. Layer-based watermarks can be removed by recipients via Adobe Pro. Use flattened for sensitive documents (confidential stamps); use layered for visible branding.
Is there a free PDF watermark tool?
Yes — our PDF Watermark tool is free, no sign-up, no daily limits, no watermarks. Add unlimited text or logo watermarks to as many PDFs as you need. All processing is local in your browser.
What opacity and color should I use?
For 'CONFIDENTIAL' stamps: red, 25% opacity, 45° diagonal. For brand logos: gray or company color, 50-70% opacity, corner placement. For 'DRAFT' watermarks: blue, 30% opacity, bottom-center. Adjust to taste — preview shows before applying.
Will my PDF or logo be uploaded?
No. pdf-lib processes everything in your browser. Whether the PDF contains proprietary designs or confidential information, and whether the logo is a registered trademark or personal mark, both stay on your device. Even saved watermark settings stay in browser localStorage only.
