About Compress PDF
Compress PDF makes PDF files smaller for email and upload limits. Choose strong, recommended or light compression and compare the sizes before downloading.
How to use Compress PDF
- Choose the PDF you want to make smaller and pick a compression level.
- Press “Compress PDF”.
- Compare the sizes and download the compressed copy.
Will compression make my PDF blurry?
Light compression keeps images sharp; strong compression gives the smallest file. Compare the sizes and check the result before you download.
Is Compress PDF free?
Yes. It is free to use, with no account, no watermark and no paywall.
Are my files uploaded?
No. It runs entirely in your browser, so your files and text stay on your device.
Tips for better results
- Use Light for PDFs made from Word or a website; it keeps the text selectable.
- Use Recommended or Strong for scans and photos, which is where the biggest savings are.
- Tick black and white when colour doesn’t matter, for example for forms and receipts.
How small will my PDF get?
It depends on what is inside. Scanned pages and photos often shrink by more than half, while PDFs that are mostly text are already small and shrink less. The tool shows the size before and after.
Can I compress a password-protected PDF?
No. Open it with its password in your PDF reader, save a copy without the password, then compress that copy.
