Compress PDF to 500 KB

Get your PDF under 500 KB automatically, at the best quality that fits.

Online forms often cap document uploads at 500 KB: marksheets, certificates, ID proofs and resumes. Choose your PDF and the tool tries progressively smaller page resolutions and qualities until the file fits under 500 KB, keeping it as readable as possible.

Most scanned documents of a few pages fit comfortably under 500 KB with clear, readable text.

How to use it

  1. Choose your PDF.
  2. It is compressed to under 500 KB straight away. Change the target if you need to.
  3. Download the compressed PDF.

Questions

Why can't my PDF reach 500 KB?

A document with many pages may not fit. Try Black & white, split it into parts, or remove unneeded pages first.

Will the text still be readable?

Yes for most documents. Open the result before uploading to check.

Are my files uploaded to a server?

No. The tool runs entirely in your browser using JavaScript, so your files never leave your device. You can even disconnect from the internet after the page loads and it keeps working.
