Frequently asked questions
How much can a PDF be compressed?
The amount of compression depends on the content — PDFs with large embedded images usually shrink the most, while text-only PDFs are already fairly small.
Will compressing reduce the quality of my PDF?
There's a small trade-off between file size and image quality, but the tool is tuned to keep text and images sharp and legible at typical compression levels.
Is this compression done online or in my browser?
It runs entirely in your browser, so your file isn't uploaded to any server.
