Shrink oversized PDFs for free so they fit email and upload limits.

Why use this free tool

Most oversized PDFs are heavy because of embedded images and duplicated fonts, not because of their content. Our optimizer downsamples images, removes duplicate resources and subsets fonts, so a scanned contract that was 24 MB usually lands between 2 and 6 MB with text that is still crisp on screen.

How does the free comprimir pdf work?

1
Upload the PDF that is too large.

Preguntas frecuentes

Which compression level should I choose?

Recommended suits email and everyday sharing. Strong is best for web uploads where size matters most. Light keeps print quality for documents you will send to a printer.

Why did my file barely get smaller?

PDFs that are mostly vector text are already efficient. The biggest savings come from documents containing photos or scans.

Is the text still searchable after compression?

Yes. Compression never rasterises existing text layers, so search and copy still work.
