Supports .pdf · Max 20 MB per file
Upload up to 10 files at once — they'll be compressed together and packed into one ZIP to download.
How to use it
Upload your PDF, choose KB or MB, and enter your exact target. The tool validates that the value is realistic before processing.
Processing method
Your file is processed on our server (temporary storage, automatically deleted after processing) because embedded PDF image recompression isn't possible purely in the browser.
When the target isn't achievable
If your requested size would require corrupting the file or destroying its usability, the tool tells you plainly and returns the smallest safe result instead.
Tips for the best result
- Scanned documents compress far more than text-native PDFs.
- Very small targets on image-heavy PDFs will show visible artifacting in those images.
Frequently Asked Questions
What's the minimum target size?+
