Reduce PDF File Size Without Losing Text Quality
Large PDFs are usually large because of the photos inside them. Compress PDF finds those images and re-saves them at a lower quality and resolution, leaving your text, links and vector graphics exactly as they are. Pick Light, Balanced or Strong, see the before-and-after size, and download only if it’s actually smaller. For stubborn files, Maximum turns pages into images for the biggest savings (text then can’t be selected).
Which level should I choose?
- Light — best quality, modest savings.
- Balanced — the best starting point for scans and presentations.
- Strong — smallest file while images stay readable.
- Maximum — every page becomes an image; use only when size matters more than selectable text.
Good to know
- PDFs that are mostly text and vector graphics have little to shrink.
- Only JPEG photos are re-encoded; other image types are left untouched.
- Compression runs on your device, so your document is never uploaded.
