Upload an image to convert it to PNG, JPEG, or WebP.
Frequently Asked Questions
Does this change the image dimensions too?
No. It keeps the original width and height and only re-encodes the image as PNG, JPEG, or WebP.
Why is PNG quality not adjustable?
PNG export through canvas does not use the same quality parameter as JPEG or WebP, so the slider is disabled when PNG is selected.
Can I compare the new file size before downloading?
Yes. The tool shows the original size, converted size, and percentage change as soon as the new preview is rendered.
Will it convert anything I upload, like vectors or documents?
It only works with files the browser can load as images. If the file cannot be decoded into an image element, conversion stops with an error.
Why did transparency behave differently after conversion?
This tool converts by drawing the source onto a canvas and exporting a new format. The result follows the target format's normal browser behavior, especially when switching away from PNG or WebP.
