Compress PDF

Shrink a PDF's file size by stripping out unused internal data and metadata and re-saving it with a more efficient structure. This tool is upfront about its limits: it does not re-encode or downscale embedded images, so savings are usually modest. You always see the exact original and new file size before downloading.

How to Use Compress PDF

1. Choose a PDF file from your device.
2. Click Compress PDF.
3. Compare the original and new size shown, then download the result.

Key Features

• Removes unused internal PDF data and document metadata
• Re-saves the file using a more efficient internal structure
• Always shows the original size and the resulting size, honestly
• Runs entirely in your browser, no upload required
• No login, no watermark, no exaggerated compression claims

Who It's Useful For

• Anyone who needs to shave a little size off a text-based PDF
• People trying to get a PDF under an email attachment size limit
• Anyone who wants a quick, honest look at how much a PDF can shrink
• Users who want metadata removed from a PDF before sharing it

Practical Examples

• Try to reduce a text-heavy report before emailing it
• Strip metadata and reduce size of a PDF before sharing publicly
• Check how much a scanned or image-heavy PDF can realistically shrink
• Clean up a PDF's internal structure before archiving it

Tips for Better Results

• PDFs that are mostly text and already efficient may show little or no reduction — that's expected and will be explained on the page
• PDFs with large embedded photos won't shrink much, since this tool never reduces image quality
• The tool always shows both the original and new size so you can judge the result yourself
