Questions

Are my images uploaded?

No. They are converted on your device in a background worker, and the downloads are created there too. Nothing is sent to a server.

Which format should I choose?

JPG for photos that need to work everywhere. PNG for screenshots, logos and anything with sharp edges or transparency; it is lossless, so files can be large. WebP is usually smaller than both at the same quality and works in all modern browsers, but some older apps can't open it.

What happens to transparent areas when converting to JPG?

JPG can't store transparency, so transparent pixels are filled with the background colour you choose. White is the default.

Can it open iPhone HEIC photos?

Only in Safari on a Mac, iPhone or iPad. Other browsers can't read HEIC. On your iPhone you can choose Settings > Camera > Formats > Most Compatible to take JPG photos instead.

Is photo information kept?

No. Converting draws the picture again, so EXIF data such as the camera model, date and GPS location is not copied. Photos are turned the right way up first, using their rotation tag.

Are there limits?

Up to 100 MB and 50 megapixels per image, and 50 images at a time. Very large images use a lot of memory, so on phones it is best to convert them a few at a time.
