How to compress a PDF
- Choose your PDF.
- Pick how much to compress: Recommended is a good balance.
- Press Compress, check the new size and download.
How it works
- Photos and scanned pages inside the PDF are re-saved as JPEG at a lower quality, and very large ones are scaled down (to 2400, 1700 or 1100 pixels on the longest side, depending on the level).
- An image is only replaced when the new version is smaller.
- Text, fonts and vector graphics are copied unchanged, so text stays sharp and selectable.
- Unused objects are removed and the file structure is packed.
When it helps
PDFs made from scans, phone photos or slides with pictures often shrink by 50–80%. PDFs that are mostly text are usually small already, so they shrink little; the tool tells you honestly when there was nothing to gain.
Your PDF stays in your browser
The file is read and changed on your device. Nothing is uploaded, so contracts, statements and IDs stay private.
Questions fréquentes
Will the text get blurry?
No. Only images are re-compressed. Text and vector drawings are not changed.
Can I compress a password-protected PDF?
Password-protected PDFs must be unlocked first with Unlock PDF (you need the password).
Is there a size limit?
No server-imposed file size limits. Very large PDFs simply need more memory and time on your device.
Is my PDF uploaded?
No. Everything happens in your browser.
