Every format you can work with in the images category. Individual tool pages list their exact input and output pairs.
Answers that apply across this category.
PNG, JPG and WebP work in modern browsers. Other formats depend on the codecs available in your browser; when a format cannot be decoded, the converter reports that instead of returning a broken file.
Lossless formats such as PNG keep every pixel. Lossy formats such as JPG and WebP let you trade a small amount of quality for a much smaller file, and the tool will make that setting explicit.
Convert and edit JPG, PNG and WebP images, remove portrait backgrounds, add watermarks, strip metadata, generate favicons and encode Base64 locally.
Conversions in this category are designed to run on your device wherever the browser makes it possible. Where a format needs a codec the browser does not ship, the tool downloads that codec as a WebAssembly module the first time you use it, and the page tells you before you start.
Nothing is uploaded for supported tools. If a future tool needs to process a file on a server, that will be stated on the tool page before you select a file, along with how long the file is kept.
