How to use Compress PDF
Choose a PDF and a compression setting, then download the result. Use Preserve document when selectable text and links matter.
Files stay in this browser
The selected files and results are processed only in this browser tab. They are not uploaded, stored, added to a URL, or sent to a third party.
Frequently asked questions
Will compression keep selectable text and links?
Preserve document keeps page content. Balanced and smaller modes turn pages into images, so selection, search, links, forms, annotations, layers, and accessibility structure are removed.
Are my files uploaded?
No. File reading, PDF processing, rendering, and ZIP creation happen locally in this browser tab.
Why are there page and file limits?
PDF rendering can use several bytes of memory per pixel. The limits keep large jobs from freezing or closing the browser tab.
