What this tool does
Image Format Converter is a local image format converter, images are processed on a local canvas and never uploaded, so both the original and the result stay on your device.
Pick a local image, process it on the page and download the result; JPG, PNG and WebP are supported.
How to use it
- Paste or type your content into the input field at the top, or press the sample button to load demo data.
- Adjust the options below the input, such as output format, separators, letter case or precision.
- Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
- When the result looks right, use the copy button in the corner, or download it as a local file.
Tips and notes
