How to use this tool

  1. Choose a PDF and keep the original copy.
  2. Select a render scale and JPEG quality. Start with Balanced and check the output before reducing quality further.
  3. Select Process file, download compressed.pdf, and compare its size and readability with the original.

Understand this compression method

This tool renders each page as an image and builds a new PDF from those images. Selectable text, links, forms and accessibility structure may be lost. Use the original document when those features matter. Lower settings can blur small print, and a file that is already compact may become larger.

Example

If a scanned document is too large for an upload, try the Balanced setting first. Inspect fine print at normal reading size before choosing a smaller setting.

Questions about this tool

Will the result always be smaller?

No. The result depends on the original document and the settings. Compare the displayed original and new sizes.

Why is text no longer searchable?

The output is image-based. Keep the original for text search, copying and accessibility needs.
