Unencrypted PDFs only. Your file stays on your device.
The first three modes turn pages into images: text is no longer selectable, and links, forms, accessibility tags and signatures are lost. Check the result.

About PDF Compressor

Choose balanced or higher-quality JPEG page compression for image-heavy documents, or a lossless structure rewrite. Lossy modes turn every page into an image, making text unselectable and removing links, forms and document structure. Results can be larger; always inspect the output.

How to use it

  1. Select an unencrypted PDF and choose a compression mode.
  2. Compress the file in your browser.
  3. Compare sizes and review the output before replacing your original.

Frequently asked questions

Will every PDF get much smaller?

No. Savings depend on the original; already-optimized or text-heavy PDFs may grow. Lower quality and resolution can reduce size but change appearance.

Will I still be able to select text?

Not in lossy image modes. They also remove links, form fields, tags and signatures. Choose the lossless rewrite to retain more structure, though its savings are usually small.
