About this tool

What is Compress PDF?

PDF compression reduces file size by optimising images, removing redundant data, and compressing content streams. A 10 MB scanned document can often be reduced to under 2 MB with no visible quality difference on screen.

FAQ

Frequently Asked Questions

How much can I reduce a PDF file size?

It depends on the content. Scanned PDFs with images typically reduce 60-80%. Text-only PDFs reduce 10-30%. Already-compressed PDFs reduce 5-15%.

Which compression level should I choose?

Use 'Recommended' for most cases — it gives the best balance. Use 'Extreme' when file size is critical (e.g. email limits). Use 'Low' for high-quality print documents.

Will compression affect text quality?

No. Text compression in PDFs is lossless — text always remains perfectly sharp regardless of compression level.

Can I compress a PDF below 1 MB?

Yes for most scanned documents and image-heavy PDFs. Text-only documents are usually already under 1 MB.

Does compression work on encrypted PDFs?

No. You need to unlock the PDF first using our Unlock PDF tool, then compress it.
