Compress PDF

Zavy PDF Compress intelligently reduces file size by optimising embedded images, removing unused objects, and applying lossless compression to text and vector elements. Choose between "balanced" (best quality/size ratio) and "strong" (maximum compression) modes.

Frequently asked questions

How much will it reduce my file size?

Typically 40–70% for image-heavy PDFs. Text-only PDFs compress less. A preview shows the estimated reduction before you download.

Will compression affect text readability?

Text and vector elements are compressed losslessly — readability is never affected. Only embedded images may see a slight quality drop in "strong" mode.

Can I compress a PDF that is already compressed?

Yes, though further reduction will be minimal if the file was already well-optimised.

Is there a file size limit for input?

Free tier: up to 25 MB input. Pro: up to 200 MB.
