About compress pdf
Reduce PDF file size by re-rendering each page at a resolution and quality you choose. This works especially well on scans, photos and image-heavy documents, where most of the file size lives. Because pages are re-rendered, text becomes part of the page image rather than selectable text — pick 300 DPI and Maximum quality if readability matters more than size.
How it works
- 1Add the PDF you want to shrink.
- 2Choose a resolution and quality — lower values mean smaller files.
- 3Compress, compare the new size against the original, and download.
Frequently asked questions
- How much smaller will my PDF get?
- Scanned and image-heavy PDFs often shrink dramatically. Text-only PDFs are already compact and may not shrink much — the result size is always shown next to the original so you can decide.
- Will the text still be selectable?
- No. This method rebuilds each page as an image, which is what makes the saving reliable. If you need selectable text, keep the original file.
- Is anything uploaded?
- No. Compression runs in your browser and the document never leaves your device.
