Compress a PDF to 50 KB
Hit a tight 50 KB cap without sending your file anywhere.
Some forms set a very tight 50 KB limit, often for a single-page document, photo or signature page. This tool targets 50 KB the moment you add a file and compresses on your device. Very heavy scans may not reach 50 KB while staying legible, so check the result.
How to compress a PDF to 50 KB

Why compress locally
A 50 KB document is often an ID or signature page. Compressing it in the browser means it is never uploaded to a compression service before you submit it where it actually belongs.
Aiming at an exact size?
Compression is really image compression, and most jobs are about hitting one specific number. We wrote up how to reach an exact size without wrecking the document, and why the work should happen on your device.
Frequently asked questions
Can any PDF reach 50 KB?+
A simple one-page or text document usually can. A dense photo scan may not compress to 50 KB and stay readable; in that case try 100 KB.
Is my file uploaded?+
No. Compression happens in your browser and nothing is sent to a server.
It will not get under 50 KB. What now?+
Set a slightly higher target like 100 KB, or use Strong quality, and confirm the text is still clear.
Is it free?+
Yes, with no sign-up.
