Frequently Asked Questions

How does the compression work?

The tool renders each PDF page as a JPEG image and rebuilds a smaller PDF in your browser. Higher quality keeps more detail but creates a larger file.

Will the output still look clear?

Use Balanced or High Quality for documents with small text or detailed images. Maximum compression is best when smaller file size matters more than fine detail.

Is it safe to compress sensitive business documents?

Yes. The entire compression process occurs locally within your browser. Your sensitive data is never sent to our servers.

Does the compression change the text to images?

Yes. The output is image-based, so text selection, links, form fields, and other interactive PDF features are not preserved. Use it for sharing a smaller visual copy, not for editable documents.
