About This Tool
Job portals, CMS systems, and email attachments all lean on a 500KB ceiling, and oversized PDFs get rejected or bounce back. This tool compresses PDFs to 500KB or less while preserving readable text and layout, with compression that runs entirely in your browser. Pick a level, check the size, and download a document that fits anywhere.

Frequently Asked Questions
Which uploads typically need a PDF under 500KB?
Resume uploads, CMS attachments, course submissions, and email attachments all commonly cap at 500KB. Compressing to this size makes a document fit nearly every destination.
Will a compressed resume still look professional?
Yes. Medium compression keeps text sharp and images clear, so a resume or cover letter reads exactly as designed at 500KB.
How do I know the file is under 500KB before downloading?
The tool shows the compressed size instantly after compression. Adjust the level and re-check until the readout lands under 500KB.
