How much can a PDF be compressed?

Compression depends on the content. PDFs with images can often be reduced by 50-80%. Text-heavy PDFs see smaller reductions.

Will compression affect text quality?

Text remains perfectly sharp. Only embedded images are recompressed, and you control the quality level.

You'll need to unlock the PDF first using our Unlock PDF tool, then compress it.
