Questions
No. Compression runs in your browser, so the file stays on your device.
With Basic, yes. Strong and Extreme redraw each page as an image to get a much smaller file, so text can no longer be selected or searched.
It depends on the file. Scans and PDFs full of photos shrink the most. A text-only PDF may barely change, and if the result isn’t smaller we tell you instead of giving you a bigger file.
Files up to 100 MB are accepted. Very large files depend on your device’s memory and may take longer.
