PDF · Up to 50 MB per fileNo upload. Your files stay on this device.It depends on the original file. We optimize PDF object streams without downsampling images. Already optimized or image-heavy PDFs may not shrink. If optimization would make the file larger, you get the original.
No intentional quality reduction is applied. This tool does not rasterize text or recompress images. It is not a strong compression option for scanned PDFs.
Choose files up to 50 MB each, with a maximum of 20 files and 100 MB combined. PDFs can contain up to 500 pages. These limits help protect your browser’s memory. Very complex documents may still exceed your device’s capacity.
