Compress PDF to 500 KB
Progressive compression passes to get your PDF under 500 KB, with the real result always visible.
Your files never leave your device
Many official forms, job portals and academic platforms cap attachments at 500 KB. This tool runs increasingly aggressive compression passes until it reaches that target. If your document can't go that low without becoming unreadable, we'll tell you clearly and hand you the real minimum achieved — we never inflate percentages or fake the result.
Frequently asked questions
Can any PDF get under 500 KB?
Not always. A long PDF full of photos has a physical minimum. If the target isn't reached, you get the smallest possible file and a clear message saying so.
What happens to quality?
We try lossless optimization first; if that's not enough, pages are recompressed as images with gradually lower resolution and quality. Text may stop being selectable at aggressive levels.
Is my PDF uploaded to a server?
No. Every compression pass runs in your browser; the document never leaves your device.
