Free PDF optimization tools
Make a PDF smaller for email or an upload portal by rebuilding its pages as JPEG images. Choose high, medium or low compression according to how much visual detail you are prepared to trade for a smaller file.
This approach can suit scans and presentation copies, but it changes the document: selectable text, search, links, and forms may be lost because every page becomes an image. Processing stays in the browser, and very large or complex files remain limited by the memory and performance of your device.
Optimization tools
- Compress PDF — Choose size or clarity.
Keep the original PDF until you have checked the compressed copy. The lower settings can reduce size more aggressively, but small type and detailed graphics may become less clear.
Frequently asked questions
Will compressing my PDF make it look worse?
It can. Lower settings discard more image detail, and every page is rasterized. Start with the high setting when small text or charts matter, then inspect the downloaded copy before printing or sharing it.
Is there a file size limit?
There is no server upload cap because the file is not uploaded, but browser memory and device performance still set practical limits. A very large or complex PDF may take longer or fail on a low-memory device.
