Options explained
Choose a target file size
Starts at 20 KB. Pick a larger quick size if your form allows more. 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 a scanned page fit within 20 KB?

Sometimes. A plain one-page scan often fits once its picture is made smaller and grey. A colour photo or a long document usually will not.

What should I do if my PDF stays above 20 KB?

Keep only the page the form asks for with Remove pages, then try again. If the form accepts images, Compress image to 20 KB can make a JPG of the page instead.

Does a 20 KB PDF keep my text readable?

Typed text stays selectable and sharp. Pictures and scans lose detail, so zoom into the preview and check names and numbers before you upload.

Is my PDF uploaded to compress it to 20 KB?

No. Your browser compresses it on this device, so nothing is uploaded.
