How to use it
Compress image-heavy PDFs for email or sharing by rendering and downsampling each page on this device. This is lossy: selectable text, forms and annotations are flattened, signatures are invalidated and reduction is not guaranteed. If the result is larger, keep the original.
- Choose an unencrypted PDF and acknowledge signature warnings if shown.
- Select the available compression quality and start processing.
- Compare file sizes, then download the result or keep the original.

Frequently asked questions
Will text and forms remain interactive?+
No. Compression rasterizes complete pages, so selectable text, forms and annotations are flattened into page images.
Are my files uploaded or stored?+
No. This tool processes supported files locally in your browser. MrTools does not receive or store their contents.
