Compress PDF
Reduce the file size of your PDF. (Basic compression: re-saves PDF, may reduce size)
Compress PDF Files Online — Free, No Upload
PDFs balloon in size fast — especially when they contain images, embedded fonts, or scanned pages. Email attachment limits, upload forms, and storage constraints make large PDFs a constant headache.
PeacefulPDF's compression tool reduces your PDF file size directly in your browser. No uploading to external servers. The tool re-saves your PDF, stripping out unused objects and redundant data. It's basic compression, but it works well for PDFs that have been through multiple edits or exports.
For PDFs with lots of high-resolution images, the savings can be significant. For already-optimized files, the reduction might be modest. Either way, your file never leaves your computer — which matters when you're compressing financial documents, medical records, or legal paperwork.

FAQ
How much will my PDF shrink?
It depends on the file. PDFs with lots of unused objects or metadata can shrink 10-50%. Already-optimized files may see minimal change.
Does compression reduce quality?
This tool re-saves the PDF without image re-compression, so visual quality stays the same. It removes structural bloat, not image data.
Is my compressed file uploaded anywhere?
No. Everything happens in your browser. The compressed file is generated locally and downloaded directly to your device.
