Reduce the size of image-heavy PDFs by re-rendering pages at a lower quality and scale. Processing runs on your device.
Choose the file you want to shrink.
Lower quality shrinks more but softens images.
Save the smaller PDF. Compare sizes and keep the one you like.
The compressor re-renders each page as an image. Text becomes part of that image, so it's no longer selectable in the output. If you need searchable text, keep the original or use a lower compression scale.
Vector-heavy PDFs can get larger when rasterized. If that happens, keep the original.
