How to use Compress PDF
Shrink PDFs for email and forms. 'Keep text' mode re-optimises the file and keeps text selectable but may save little. 'Strong' mode converts pages to compressed images for big savings, but text is no longer selectable or searchable. Each result shows the real size, and a file is rejected if it did not get smaller.
- Add one or many PDFs.
- Pick 'Keep text' or 'Strong' and the quality.
- Process, check the new size, then download.
FAQ
Are my PDFs uploaded anywhere?
No. PDFs are rendered and processed inside your browser and never leave your device.
Why did a PDF not get smaller?
Many PDFs are already optimised. Try Strong mode, or lower the quality/resolution. If the result would be bigger than the original, the tool tells you instead of giving you a worse file.
Does Strong mode lose text?
Yes. Pages become images, so text can't be selected or searched. Use it for scans and form uploads, not for documents you need to edit or search.
