Frequently asked questions
How do I reduce the size of a PDF?
Add the PDF, keep “Recommended” and click “Compress PDF”. Use “Strong” if it still has to get smaller.
Will the quality get worse?
Recommended keeps documents easy to read. Strong is smaller but softer. Lossless changes nothing visible but saves less.
Why can’t I select text after compressing?
Recommended and Strong save each page as an image, which is what makes them so small. Choose Lossless to keep selectable text.
Are my files uploaded?
No. Everything runs in your browser; your PDF never leaves your device.
Is it free?
Yes. No sign-up, no watermark and no limit on the number or size of files.
