📖 How to Use
Reduce PDF file size by restructuring internal objects and stripping unnecessary metadata — all done locally in your browser.
Step-by-step
- Click to upload your PDF file
- Click Compress PDF and wait a few seconds
- Review the comparison — original size vs. compressed size vs. % saved
- Download the compressed version if it's smaller
💡 Tips
- Best results on PDFs that were exported from Word, Google Docs, or other office software (they often contain redundant data)
- Image-heavy PDFs (scanned documents, photo albums) may see minimal reduction since images are already compressed
- For major compression of image-heavy PDFs, consider re-saving from the source application at lower image quality
Note: Browser-based compression restructures PDF object streams and removes metadata. It cannot re-compress embedded images. For aggressive compression, use dedicated desktop software.
