Your files never leave your device.
Recompresses images, optimizes fonts and removes unused data. Text stays selectable, and links and form fields keep working. Runs on your device with the open-source Hyper Compress engine.
QPDF looks for the best quality that fits and tells you if the target cannot be reached. Leave empty to use the level as is.
Fine-tune the compression engine. Picking a compression level resets these, except Override content protection, Convert to grayscale, Preserve PDF/A, and Brotli.

Email services commonly limit attachments to somewhere between 10 and 25 MB, and the message as a whole is larger than the file itself. This preset targets 10 MB to leave room for encoding overhead.
This tool runs entirely in your browser. Your file is read from your device, processed in memory, and saved back to your device — it is never uploaded to QPDF or anyone else. Once this page has loaded, the tool also works with your internet connection switched off.
