Quality presets

Choose screen (smallest), ebook (balanced), printer or prepress (highest quality) in the convert step — they map to Ghostscript's downsampling presets.

Keeps your text

Re-encoding compresses embedded images and subsets fonts without rasterizing the page, so selectable text stays selectable.

Frequently asked questions

How do I compress a PDF?

Drop your PDF above. The converter is pre-set to re-encode it with the “ebook” quality preset; download the smaller PDF. Switch presets in the convert step for more or less compression.

Will it ruin the quality?

“ebook” downsamples images to a screen-friendly resolution while keeping text crisp. For print, choose “printer” or “prepress”; for the smallest possible file, choose “screen”.

Is it private?

Yes — uploads are over an encrypted connection and anonymous files are temporary. No account needed.
