Compress a PDF to a smaller file size.
Shrink a PDF for email, an upload portal or a form with a size limit. Pyrbit PDF recompresses the images inside the file while keeping text and links intact — or aims for the exact size you need.

How it works
Compress PDF in three steps.
Choose a PDF or a photo
Select the file to shrink. Photos can be compressed too.
Pick a level or a target size
Light keeps the best quality, Balanced is recommended, Strong makes it smaller. For PDFs you can also aim for 100 KB, 500 KB, 1 MB or 2 MB.
Download the smaller file
You see the size before and after. If the file can’t get smaller without losing quality, it’s kept as it was.
What you can do
What Compress PDF does.
- Light, Balanced and Strong levels that keep text and links
- Target sizes of 100 KB, 500 KB, 1 MB and 2 MB for upload limits
- “Smallest” turns pages into pictures for the biggest saving
- Compresses photos as well as PDFs
- Shows the size before and after, and never makes a file bigger
Private by design
Your PDF never leaves your device.
Compress PDF runs inside your browser tab. The file you choose is read from your device, processed there, and the result is saved back to your device — it is never uploaded to a Pyrbit server, so there is no copy to keep or delete.
Processed in your browser
The Pyrbit PDF engine runs on your computer or phone, not in the cloud.
No upload
Your document isn’t sent anywhere — not to us, and not to a third-party converter.
Sign-in is for your plan only
Your Google account keeps track of your free daily document and Pyrbit Pro. It never gives us your files.

FAQ
Compress PDF questions.
Will compressing make my text blurry?
No for the Light, Balanced and Strong levels — they recompress pictures inside the PDF and keep text as text. Only the Smallest level turns pages into pictures, which makes text unselectable.
How do I get a PDF under 1 MB or 100 KB?
Choose the target size you need. The tool works out how much to compress the images to get as close as it can under that size.
Why didn’t my file get smaller?
Some PDFs are already compressed, or are mostly text. When the result would be the same size or bigger, Pyrbit PDF keeps your original rather than give you a worse copy.
