Frequently asked
Will my PDF always fit under 10 MB?
In most cases yes. Very long or image-heavy PDFs may not fit without dropping content - the tool will tell you the best size it could reach.
Are my files uploaded?
No. Compression runs entirely in your browser using JavaScript. Files never leave your device.
How does the tool decide when to stop?
It runs a series of quality passes from best to most aggressive and stops the first time the output fits under the target size.
Will text still be readable?
Usually yes. Aggressive passes rasterize pages to JPEG, which can soften small text. Try a higher target first if sharpness matters.
