Compress a PDF to 100 KB

Compress a PDF down to 100 KB in your browser. The target is set for you and multiple passes run until the file fits. Free, no signup, nothing uploaded.

Upload forms and government portals often cap attachments at 100 KB. This page opens the compressor with a 100 KB target already set: it retries at progressively lower quality until the output fits, and tells you the real size when it is done.

How it works

  1. Add your PDF — it is read in the browser and never uploaded.
  2. The 100 KB target is already set for this page.
  3. Compression runs in passes, lowering image quality each time until the output fits.
  4. Download the result. The real size is shown, and if the target could not be met you are told the best achieved.
