Why there's no upload step
A 50KB PDF limit is the strictest you'll meet in the wild — typically on exam registrations and government application systems expecting a single-page scanned certificate or signature document. Hitting it means re-rendering each page as a compact image and rebuilding the PDF; this tool searches for the best quality that still fits, entirely in your browser, so ID scans and certificates never leave your device.
Is my document uploaded anywhere first?+
No — compression happens entirely in your browser, which matters most for exactly the ID and certificate scans these portals ask for.
Can every PDF reach 50KB?+
A single-page scan usually can. Multi-page or graphics-heavy PDFs often can't at readable quality — the tool tells you honestly when it could only get close, rather than silently mangling the pages.
Will text stay selectable?+
No — pages are converted to images to hit a target this tight, so text stops being selectable. Portals only check the file size, not the text layer.
The portal allows 100KB — should I use that instead?+
Yes — use the Compress PDF to 100KB page. Every extra KB of budget buys visible quality at these sizes.
