Compress a PDF to 100 KB
Hit a 100 KB upload limit without sending your file anywhere.
Plenty of government and exam portals cap document uploads at 100 KB, and a normal scan is far larger. This tool is set to target 100 KB the moment you add a file: it shrinks the PDF on your device to fit, without uploading it to a compression server.

Why compress on your device
Documents you upload to portals often contain personal details. Compressing in the browser means the file is never sent to a compression service, so there is no extra copy of your ID or certificate on someone else’s server.
Frequently asked questions
Which forms need a 100 KB PDF?+
Many exam and recruitment portals (and some certificate uploads) cap documents near 100 KB. Always check the exact limit on the form, then set the target to match.
Is my document uploaded?+
No. Compression runs in your browser, so the file is never sent to a server.
What if 100 KB makes it unreadable?+
A heavy scan may not reach 100 KB while staying legible. Try 150 to 200 KB, or use the Strong quality mode, and check the text is still clear.
Is it free?+
Yes, with no sign-up.
