Converts an image between PNG, JPEG and WebP.
The Image Format Converter turns an image into PNG, JPEG or WebP right in your browser. Drop in any image your browser can decode, pick the target format, optionally set a quality value, and download the converted file. It is handy whenever you need to switch image formats quickly without installing software or uploading files to an online service.
No. Conversion happens entirely in your browser using the HTML canvas API, and the image never leaves your device. Nothing is uploaded, so it works offline once the page is loaded.
You can export to PNG, JPEG or WebP. The input can be any image format your browser is able to decode, since the file is loaded through the browser's built-in image decoder.
The quality value is a number between 0 and 1 (default 0.92) passed to the encoder. It affects lossy formats like JPEG and WebP, where lower values produce smaller files with more compression. It has no effect on lossless PNG output.
JPEG does not support an alpha channel, so transparent areas are flattened when you export to JPEG. Use PNG or WebP if you need to keep transparency.
No. The image is drawn to a canvas at its natural width and height, so the output keeps the original pixel dimensions and only the encoding format changes.
