Runs 100% in your browser
Your data never leaves your device. zero uploads.
Reduce a PDF's file size for an attachment or submission, with local processing and adjustable output quality.
The file is compressed on your device — it never leaves your browser.
When a file exceeds a destination's size limit, compare quality presets to find an acceptable tradeoff. Start with a less aggressive setting, inspect the output, and try a smaller result only if needed. The tool reports sizes so you can compare the actual change.
If a document is above an email attachment limit, run a compression preset and check the downloaded file's size. Review every page containing small labels or diagrams.
There is no guaranteed target size such as 100 KB or 1 MB. Output depends on the source document, and reduced quality can remove detail or text-layer features.
Open the PDF you want to reduce. Choose a compression quality preset and run the process. Compare the output size and visual quality before saving the result.
