WHAT IS PDF COMPRESSOR?

PDF Compressor offers two honest compression modes: a non-destructive "Preserve document" mode (keeps selectable text, links, and forms) and a destructive but often much smaller "Rasterize" mode — all processing happens entirely in your browser.

Features

  1. Preserve document mode: no page content is converted. The size reduction depends on how optimized the source already is, and may be small — the tool reports this honestly.
  2. Rasterize mode: converts every page to an image and rebuilds the PDF — usually a much bigger reduction, but selectable text, links, form fields, and accessibility structure are lost. This tradeoff is shown before processing.
  3. Three rasterize quality presets: Better Quality, Recommended, and Smaller File.
  4. Encrypted/password-protected PDFs show a clear message instead of crashing or producing a corrupt file.

How to use?

  1. Drag or click to upload PDF files (multiple allowed).
  2. Choose "Preserve document" or "Rasterize" mode, and a quality preset if needed.
  3. Click "Compress", then download individually or via ZIP.

Frequently asked questions

Does "Preserve document" mode always reduce file size?

Not always. This mode never converts page content, so if the source PDF is already well-optimized, the reduction may be small or zero — the tool honestly reports "no size reduction" and suggests Rasterize mode instead.

What does Rasterize mode lose?

Selectable text, links, form fields, and accessibility structure — every page becomes a single flattened image. This tradeoff is shown clearly before processing, never as a surprise afterward.

Can encrypted PDFs be compressed?

Not currently. The tool shows a clear "encrypted" message instead of crashing or producing a corrupt file.
