Use PDF compression to reduce the weight of a scanned document or image-heavy attachment. A mostly textual PDF may benefit less; inspect fine print and diagrams in the downloaded copy.
Example: when to use this tool
A scanned report exceeds a form upload limit. Compress a copy and inspect small print and diagrams. Keep the original, especially if it contains signatures or interactive fields.
Quality and output
PDF compression rewrites the document and may downsample or re-encode images. It is not a lossless-file guarantee and does not promise preservation of signatures or interactive features.
How to use
- Upload a valid PDF file.
- Choose a compression setting and start processing.
- Download the result and check it before replacing your original.
Before you download
Check every page, readable text and important diagrams. Do not use a recompressed PDF as the only copy of a signed, interactive or archival document.
