What is Image Format Converter?
Image Format Converter changes an image between PNG, JPEG, and WebP with a single canvas re-encode in your browser. Drop in a file, pick a target format, and the preview and file size update automatically so you can compare before saving. Nothing is uploaded, so your image stays entirely on your device.
How to use Image Format Converter
Add your image
Drop an image onto the drop zone. The tool detects its current format and shows it as the read-only source format.
Pick a target format
Choose PNG, JPEG, or WebP. It defaults to a format different from the source, and the image is re-encoded immediately whenever you change it.
Preview the result
The converted image appears in the preview, and a summary line shows the source format and size next to the target format and size, including how much smaller or larger the result is.
Download the converted file
Click Download to save the image in the new format, named after your original file with the correct extension.
