About Compress PDF
How it works
Choose light, balanced or maximum compression, then compare the finished file with the original before downloading.

Make image-heavy reports, presentations and scanned documents easier to email, share or submit online.
Keep in mind
Results depend on the document. A text-only or already compressed PDF may stay the same size or become slightly larger.
Frequently asked questions
Does Compress PDF upload my file automatically?
No. Processing starts on your device. If an optional server service is available, the tool explains it and asks before uploading anything.
Why did compression not reduce my PDF?
The PDF may contain few images or may already be compressed. The result section always shows the actual file size.
