Compress PDF
Reduce PDF file size in your browser without uploading it, while keeping text and page dimensions intact.
About this tool
Compress PDF files in your browser by re-encoding supported images, without rasterizing pages or uploading the file.
How to use this tool
- Choose or drop a PDF file.
- Select a compression level.
- Review the size and percentage, then download the result.
Practical example
A report with large photos may shrink substantially at the Balanced level while its text stays selectable and searchable.
Important notes
- The original file is never modified or overwritten.
- Unsupported images are left untouched and the result details explain what was skipped.
- Encrypted PDFs are rejected safely without attempting to bypass protection.
