Compress PDF to 50 KB
Hit the strict 50 KB cap used by many government and exam portals without uploading your document to anyone.
Files are optimized losslessly when possible. To guarantee an exact size, larger files are converted to images, which can soften text and remove the selectable text layer.

Frequently asked questions
Are my files uploaded to a server?
No. Compression runs entirely in your browser using WebAssembly. Your PDF never leaves your device, which makes this safe for KYC, banking, and government documents.
How do you hit exactly 50 KB?
We re-encode each page as an image and search across quality and resolution settings until the rebuilt PDF lands at or just under 50 KB, keeping the best quality that still fits.
Is it really free with no watermark?
Yes. No sign-in, no per-hour task caps, no watermark, and no file-count limits, unlike most incumbents.
Will the text stay selectable?
To guarantee an exact size target, pages are rasterized, so text becomes part of the image. For upload-to-portal use cases this is exactly what is needed. If you need selectable text, keep your original.
