Compress PDF
Reduce the size of a PDF, by tidying its structure or by re-rendering the pages at a lower resolution.

How to use the Compress PDF
- Drop a PDF.
- Choose how to compress it: keep the text, or re-render the pages for a smaller file.
- Compare the sizes and download the result only if it is worth keeping.
Two methods, and what each one costs
Tidy structure keeps everything as it is, including selectable text, but often saves little: images inside the file are not recompressed.
Re-render pages turns each page into a JPEG at the resolution you choose. It can shrink scanned documents a lot, but the result is image-based, so its text cannot be selected or searched. It can make a text-only PDF larger, and the tool tells you when that happens.
The file is processed in your browser and is not uploaded to our server. When an administrator has installed Ghostscript, a third method recompresses images while keeping text; that one uploads the file for processing and deletes it automatically.
