Frequently asked questions

Which formats can I convert to?

PNG, JPG and WebP. You can open most images your browser can display, such as PNG, JPG, WebP or GIF; an animated GIF may be converted as a single frame.

What happens to a transparent background when I convert PNG to JPG?

JPG cannot store transparency, so transparent areas are filled in. Convert to PNG or WebP to keep a transparent background.

Does converting to WebP make files smaller?

WebP files are usually smaller than PNG or JPG at similar quality, but it depends on the image. Use the quality slider to balance size and quality.

Is my image uploaded?

No. The image is converted with the browser canvas on your device and never leaves it.
