How much can I shrink a PDF?

Typically 30-70% smaller, depending on content. Image-heavy PDFs compress more, text-heavy PDFs less. Our compressor is smart — it preserves text sharpness while aggressively resizing images.

Will PDF compression reduce image quality?

We use smart lossy compression. Text stays pixel-perfect, images get re-encoded at a reasonable quality. For most uses (email, web forms), you won't notice the difference.

Can I compress a PDF to exactly 200 KB?

Yes. Pick a target size from the preset list (100 KB, 200 KB, 500 KB, 1 MB, 2 MB). The tool compresses iteratively until it hits your target.

Is there a file size limit for PDF compression?

No. We don't impose a limit. Your browser and computer are the only constraints — typically PDFs up to 500 MB work fine.

Can I batch-compress multiple PDFs?

Yes. Drop multiple PDFs at once and they'll all be compressed with the same settings. Download them individually or as a ZIP.

How does PDF compression work without uploading?

The compression runs entirely in your browser using pdf-lib + canvas APIs. Your PDF stays on your device. Zero servers, zero uploads, zero tracking.

What's the difference between compress and resize?

Compress reduces file size while keeping page dimensions the same. Resize changes page dimensions (A4 to Letter). Use compress for emails, resize for international standards.
