About this tool
Compress PDF to 500KB Online
Government portals, job applications and university forms often only accept PDFs under 500 KB. This tool shrinks your PDF below that limit automatically. First it tries a lossless clean-up, which keeps the text selectable. If that isn't enough, it turns the pages into images at the highest quality that still fits under 500 KB.
Scanned documents such as marksheets, certificates, ID cards and bank statements shrink the most. If a very long PDF can't get under the limit, split it into smaller parts with Split PDF.
The whole process runs in your browser, so your documents are never uploaded. That makes it safe for private files such as Aadhaar, PAN and bank documents.
Always under 500 KB
The tool keeps trying lower settings until the PDF fits, and tells you if it can't.
Best quality that fits
It stops at the first setting that fits, so pages stay as sharp as possible.
Keeps text when possible
If a lossless clean-up is enough, the text stays selectable and searchable.
Private
Documents never leave your device. Nothing is uploaded.
