FAQ

Compress PDF questions, answered

How do I compress a PDF for free?

Open your PDF, keep Recommended selected, click Compress PDF, then download the smaller file. There's no sign-up and no watermark.

How much smaller will my PDF get?

PDFs with photos or scans usually shrink by 50–90%. PDFs that are mostly text are often already small, so they shrink less. Raha shows the exact saving for every file.

Will compression make my PDF blurry?

Text and vector graphics stay perfectly sharp, because only images are recompressed. With Recommended, images still look sharp on screen. Use Less or Custom for print quality.

Can a compressed file be bigger than the original?

No. If compression wouldn't make a file smaller, Raha gives you the original back.

Can I compress several PDFs at once?

Yes. Add several files, compress them together, and download them as a ZIP.

Are my files uploaded?

No. Compression runs in your web browser. Your PDFs never leave your device.

Can I remove metadata while compressing?

Yes. Tick Remove metadata to strip the title, author and software details.

Is Compress PDF free?

Yes. The free plan needs no account and adds no watermark. It includes 3 tasks per hour, with files up to 50 MB and 200 pages. The Pro plan removes the limits.
