Cómo Usar
- Drop All JPGs: Drag your JPGs in — 1, 10, 100, or more. The tool shows a thumbnail grid. Multi-select supported (Ctrl/Cmd+click for individual, Shift+click for ranges).
- Arrange Order: Drag thumbnails to reorder. Most users sort by date or filename alphabetically. Match filenames to dates (e.g. 'IMG_20260101.jpg') for natural ordering.
- Set Page Settings: Choose page size (A4 / Letter / match image dimensions), orientation (auto-rotate based on image, portrait, landscape), and fitting (fit-with-margin, fill-and-crop, exact-size).
- Convert Bulk: Click 'Convert'. pdf-lib processes each image into a PDF page in your browser. 100 images convert in about 15-30 seconds on a modern device. Output is one PDF with N pages (one per image).

Preguntas Frecuentes
How do I combine 100 JPGs into one PDF?
Drop all 100 images into our Image to PDF tool, arrange them in order (by drag-and-drop), set page settings (A4 or match image dimensions), click 'Convert'. Within 30 seconds you have a single PDF with all 100 images as pages. No upload, no daily limits.
How big can the batch be?
We've tested batches up to 500 images. The limitation is your device's memory and browser. For very large collections (1000+ images), split into chunks or use a dedicated desktop app. For most use cases (a vacation's photos, a project archive, a product catalog), 50-200 images per session is comfortable.
Can I control the page size?
Yes — three options: (1) Match image — each page is the image's pixel dimensions in PDF units (best for full-resolution photos), (2) Fit A4/Letter — pages are standard size, images fit with margins, (3) Custom dimensions — specify width × height in mm or inches. Use 'Match image' for preserving every pixel; use 'A4' for printable consistency.
Will the JPG quality be lost?
By default, no — we embed images at full resolution. To reduce file size, choose 'Fit A4 page with margins' (we downscale) or compress the resulting PDF with our PDF Compress tool. For maximum quality preservation, use the 'Match image dimensions' option.
Will my photos be uploaded?
No. pdf-lib processes everything in your browser. Whether the JPGs are private family photos, client work, medical images, or confidential documents, they stay on your device. Output PDF is created locally.
Can I add text or labels to each page?
Yes — for caption-style labels, switch to 'Advanced mode' and add caption text per image (filename, date, or custom). For full design control, use the PDF Watermark tool to stamp text on every page after conversion.
