PDF Compress
Rebuild the PDF's internal structure (object streams) and strip unnecessary metadata to reduce file size. Files are processed entirely in your browser.
- 1.Select or drag in a file
- 2.Adjust the options you need
- 3.Click “Compress”
- 4.Download the resulting file
→ Output: A size-reduced PDF file
Image-heavy PDFs are not re-compressed at the image level, so savings may be small. This works best for text/vector PDFs or files with lots of unnecessary metadata.

About this tool
Reduces PDF file size by tidying its internal structure and stripping unnecessary information. Processing happens in the browser and the document is never transmitted.
When to use it
- —Shrinking a document that exceeds an email attachment limit
- —Meeting a submission system's file size rule
- —Lightening scanned documents kept for archiving
Good to know
- —Because it works by restructuring and removing metadata, image-heavy scans may not shrink much.
- —If the size barely moves, the scan resolution itself is high; rescan or reduce the images first.
- —Metadata such as author and revision history is removed too, so check whether you need it.
