Frequently asked questions
Are my images uploaded to a server?
No. Conversion happens on a canvas inside your browser and nothing leaves your device.
Why did my file get bigger?
Converting a compressed JPG to lossless PNG almost always increases the size. Choose WebP or JPG if a small file is the goal.
What happens to transparency?
PNG and WebP keep transparent areas. Converting to JPG fills them with white, since JPG cannot store transparency.
Is there a limit on the number of files?
There is no fixed limit, but very large batches use a lot of memory. Convert in groups of around twenty for the smoothest experience.
