Limits & privacy

Processed in a bounded worker without storing files. Up to 10 MiB of file input and 200 pages. Encrypted or damaged PDFs are unsupported. This optimizes document structure; it does not downsample images or guarantee a smaller file. Digital signatures can be invalidated by rewriting. The original is returned if the rewritten file is larger.

Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
