Compress PDF to 500KB: how it works
Upload portals often reject a PDF that's even slightly over 500KB. Instead of guessing a compression level, add your PDF here: FileStripe renders every page at the highest resolution and JPEG quality that still keeps the whole file under 500KB, then rebuilds it.
At 500KB, most scanned documents of up to 20-30 pages stay sharp and easy to read. Very long or photo-heavy PDFs may need grayscale or splitting.

Frequently asked questions
How do I reduce a PDF to 500KB without losing quality?
Some loss is unavoidable when a scan has to fit in 500KB, but FileStripe keeps as much as possible: it tries high resolutions first and only lowers them if the file won't fit. Text-heavy scans usually stay crisp.
Will the text still be selectable?
No. To reach a specific size, pages are converted to optimised images, the same way scanners create PDFs. Keep the original if you need to copy text.
Is my PDF uploaded?
No. The compression runs in your browser, so confidential documents like ID scans and certificates never leave your device.
Is the Compress PDF to 500KB free?
Yes. The Compress PDF to 500KB is completely free with no sign-up, no watermarks, no daily limits and no premium tier.
Are my files uploaded to a server?
No. FileStripe processes your files locally in your web browser using JavaScript. Nothing is uploaded, so the Compress PDF to 500KB is safe for private photos and confidential documents and even works offline once the page has loaded.
Does it work on iPhone and Android?
Yes. The Compress PDF to 500KB works in Safari, Chrome, Firefox, Edge and Samsung Internet on phones, tablets and computers. On a phone you can pick files from your photo library or files app and share the result straight to another app.
