Question 1

Which formats can I convert?

Accepted Answer

Input: WebP, HEIC/HEIF (iPhone photos), AVIF, PNG, JPG, GIF (first frame), BMP, TIFF and SVG. Output: JPG, PNG, WebP and AVIF. The format is detected from the file's contents, so renamed files (say, a PNG called .jpg) still open. Animation isn't preserved — the first frame is used.

Question 2

Are my photos uploaded to a server?

Accepted Answer

No. All conversion happens in your browser and your images are never sent anywhere. Only the decoder libraries themselves (for HEIC, for example) are fetched from the network, and only when needed — your files aren't transmitted in the process.

Question 3

Why did my transparent PNG or WebP get a black background as JPG, and how do I make it white?

Accepted Answer

JPG can't store transparency, and many converters simply turn transparent pixels black. Here the transparent areas are filled with a colour you choose — white by default, changeable in the settings. If you need to keep transparency, choose PNG, WebP or AVIF instead.

Question 4

How do I convert iPhone HEIC to JPG without losing quality, and keep the date taken?

Accepted Answer

Add the HEIC files, choose JPG and a quality of 90–95. To keep the date and camera model, set metadata to “Keep, but remove GPS” (or “Keep everything”). Note that any JPG is lossy, so the file can end up larger than the HEIC, and very large photos may hit memory limits.
