Compress PDF to 10 MB help

Choose a PDF and try to bring it under 10 MB. Some upload forms set a 10 MB limit, and long scans, photo reports or slide decks saved as PDF often go over it. Text stays selectable, and the page tells you if the result misses the limit.

Options explained
Choose a target file size
Starts at 10 MB. Pick a different quick size if your limit is lower. Sizes use 1024 bytes per KB.
Remove saved document details
Optionally remove title and author properties; names printed on pages remain.
Use stronger compression
Works best with scanned PDFs and PDFs with images. Images may look blurry or lose detail. Check small print in the preview. Your target size is not guaranteed.
Limits and supported files

Unlocked PDF documents, including text and images. Signed files require confirmation to create a changed copy.

The requested size is an aim, not a guarantee. Large image files may stay above it even after compression. Stronger compression can make images noticeably softer; review the preview.

Tests covered 1,000 simple text pages and generated image PDFs up to 200 MB. Large files may use the full search time and remain above your target.

Tested in Chromium, Firefox and WebKit. Large-file checks used a 100 KB target.

Questions

Can every PDF fit within 10 MB?

Most can, but a very long scan may not. You get the smallest copy it found, and the page tells you if it missed 10 MB.

Will compressing to 10 MB lower the quality much?

Often very little, because 10 MB leaves plenty of room. Only pictures are resized or saved at lower quality. Zoom into the preview to be sure.

How long does a big PDF take to compress?

It depends on the file and your device. Long scans take the longest. You can cancel at any time.

Is my PDF uploaded to compress it to 10 MB?

No. Your browser does the work on this device, so even a very large PDF is never uploaded.
