Step by step
How to compress a PDF
Compression works best on PDFs built from photos or scans, where the images take up most of the space.
Choose a level
Pick a compression level: Light keeps the most detail, Strong makes the smallest file, Medium sits in between.
Resize if needed
For very large scans, set a page size such as A4 to bring the dimensions and file size down further.
Download the smaller file
Click Download PDF and save the lighter version to your device.

FAQ
Compressing PDFs: common questions
How much smaller will my PDF get?
It depends on what is inside. PDFs full of photos or scans shrink the most. A file that is mostly plain text is already small, so there is less to save.
Will compressing blur my text?
Text on real PDF pages stays sharp. Compression mainly re-encodes the images, so choose Light if you want to keep the most image detail.
What is the best level to pick?
Start with Medium. If the file is still too big, try Strong. If quality matters more than size, use Light.
Is there a file size limit?
There is no fixed limit. Very large files use more of your device's memory, so they can take longer to process.
Are my files uploaded to compress them?
No. Compression happens in the page on your device. Nothing is sent to a server.
