Compress a PDF. No upload.
Make a scanned or photo-heavy PDF smaller. Choose quality and resolution, and the page shows the size before and after. Your file never leaves your device.

Questions
How does compress work, and what does it cost?
It redraws every page as an image and rebuilds the PDF from those images. That can shrink scans and photo-heavy PDFs a lot. The text in the new file is no longer selectable or searchable. If the result is not smaller than your original, the page says so and you keep the original.
Should I use it on a PDF that already has searchable text?
Usually not. Because pages become images, the text is lost. Use it for scans and photo PDFs. If you need a scan to be searchable, run it through the OCR Toolkit after compressing.
How small will my file get?
It depends on the file. Scans of photos shrink the most. Text PDFs and files that are already compressed may not get smaller. The page shows the real size before and after, so you can see the result.
Is my file uploaded?
No. The file is read and changed by code running in this page. Nothing is sent to a server, so contracts, IDs and bank statements stay on your device. The hosted page may load tool files when needed. Use the separate offline pack for reliable disconnected operation.
What are the limits?
The free page makes up to 100 pages per output file, and everything runs in your browser memory, so a file of several hundred MB may be slow or fail. The offline pack removes the page limit.
