Compress PDF to 500KB
Choose a PDF and it is made just under 500 KB, keeping as much quality as possible. Ideal for email attachments and most upload forms.
How to compress a PDF to 500KB
- Choose your PDF.
- The target is already set to 500 KB. Change it if your form allows a different size.
- Press Compress PDF and download the smaller file.
How it works
Each page is re-saved as a compressed image. The tool tries several quality levels and keeps the sharpest one that still fits under 500 KB. Your file never leaves your device.
Tips
- Scanned documents and PDFs full of photos shrink the most.
- Fewer pages means better quality at 500 KB. Remove pages you don't need with Split PDF first.
- Text in the result can no longer be selected or searched, which is fine for forms and scans.
Questions
What if my PDF can't get under 500KB?
The tool shows the smallest size it could reach. Split the PDF into parts or remove pages, then try again.
Is my PDF uploaded?
No. Compression happens inside your browser, so the file stays on your device.
