Shrink a PDF by downsampling embedded images and stripping unused data. See the original size, the new size and the percentage saved before you download.

One PDF, up to 50 MB
Choose the PDF you want to make smaller.
Choose Strong, Balanced or Light. Stronger settings downsample images more aggressively.
The tool shows the original size, the compressed size and the reduction. Download if you are happy with the trade-off.
Each page is rasterised at 150 DPI, saved as JPEG at quality 70, and reassembled. The scanned text remains clearly legible while the file becomes small enough to email.
Desktop tools like Acrobat use a print engine (Ghostscript-style) to rebuild a PDF from scratch. That is not available in a browser, so this tool takes a pragmatic approach: it re-renders image-heavy pages at a lower resolution, re-encodes them as efficient JPEGs, and removes metadata and orphaned objects.
For scanned documents and image-rich brochures this often cuts the file by 40–70%. For a PDF that is mostly text, the savings are small because the text is already compact — in that case the tool mainly strips metadata.
Text in a PDF is stored as compact font instructions that are already compressed. There is little to remove. Compression mainly helps files that contain scanned pages or photographs.
In Light mode, yes. In Balanced and Strong mode, image-heavy pages may be rasterised, which can turn selectable text into an image. The tool tells you when this happens.
No. All rendering and re-encoding happens on your device.
You can, but expect minimal change. The before/after comparison will make the trade-off obvious.
