Compress a PDF to 500KB
Reduce a PDF towards a 500KB limit while keeping it comfortably readable. The Balanced level is preselected, which reaches this target for most documents.

Compression runs on your device, so your document is never uploaded.
A practical target
A 500KB cap is far more achievable than 100KB and is common on university portals and job application forms. Most scanned documents of up to about ten pages will fit at the Balanced setting while remaining perfectly legible.
Check the result before submitting
After compressing, open the downloaded file and read it at full size, paying attention to small print and any handwriting. It is much better to discover a problem now than after an application has been rejected.
Frequently asked questions
Will 500KB be readable?
For a typical scanned document, yes, comfortably. At this size text stays clear and stamps or signatures remain identifiable.
My PDF is already under 500KB — do I need this?
No. If your file already meets the limit, submit it as it is. Compressing an already small PDF only loses quality for no benefit.
