pdf-compress

Runs in your own browser. Analyses the byte budget of the document and re-compresses embedded images by their EFFECTIVE resolution, leaving the text layer intact — so the result stays searchable and selectable. The default mode chooses the settings itself.

This tool runs in your own browser. The work order you receive carries this recipe with the placeholders filled in; the selectors below are a versioned contract, not implementation detail — they do not change without a version bump.

This contract cannot change without a new version and a line above: a test compares the published schema, pricing and limits against a committed lockfile and fails the build otherwise. Subscribe to /v1/changelog to be told when something moves.
