When to compress

Use compression for heavy scans, presentations and attachments that are too large.

Each page is recreated as a JPEG image. Selectable text, links, forms, accessibility tags and digital signatures may be lost.

The right order

Compress the final PDF after sorting or merging to avoid repeated processing.

Frequently asked questions

Can quality or document structure be lost?

Yes. This is lossy compression. Work on a copy, do not use a signed PDF and always review the result.

Is processing local?

Yes. The site does not send the document to an external service for this task.
