Compress PDF reduces the file size of a PDF so it is easier to email, upload to a form or store. Many websites and mail services limit attachments, and a smaller file also opens faster on slow connections.
The tool rebuilds your document in a smaller form and gives you a new file to download. How much smaller it gets depends on what is inside. Documents full of photos and scans usually shrink the most, while a PDF that is mostly text may already be small. The upload limit is 20 MB.
How to use Compress PDF
- Click the upload field and choose your PDF (up to 20 MB).
- Press Generate and wait while the file is processed.
- Download the compressed PDF.
- Compare the new size with the original and open the file to check it looks good.
Tips for better results
- Always keep the original. If the compressed version looks too soft, you can go back to it.
- Scanned documents are often large because every page is a picture, so they benefit most from compression.
- If the size barely changes, the file was probably already optimized.
Frequently asked questions
Will the quality get worse?
Making a file smaller can lower the quality of the pictures inside it, so open the result and check it before you replace the original.
How much smaller will my file be?
It varies a lot from file to file. Image-heavy PDFs usually gain the most.
Is the text still selectable?
Open the compressed file and try to select text. Keep the original if you rely on that.
