Frequently asked questions
How much smaller will my images get?
Most photos shrink by 40–70% with no visible difference, depending on the original. Use the quality slider to push for maximum savings or to keep images pixel-perfect.
Does compressing reduce image quality?
The default settings target visually lossless results, so the difference is hard to see. You stay in control with the quality slider if you want to trade a little sharpness for an even smaller file.
Which image formats can I compress?
You can compress JPG and PNG images, and each file keeps its original format after compression. Drop a mixed batch and FileFlow handles them all.
Are my files uploaded to a server?
No. FileFlow runs entirely in your browser using JavaScript — your files are read, processed, and saved on your own device and never travel across the internet. There is literally no server to upload to.
Is there a file size or file count limit?
There is no artificial cap. Because everything runs locally, the only limit is your device’s available memory — most files of any normal size process in a couple of seconds.
