Frequently asked questions
Is this image converter really free?
Yes. There is no account, no watermark and no daily limit. Because every conversion runs on your own device, there are no server costs to pass on to you.
Are my images uploaded to a server?
No. The converter is compiled to WebAssembly and runs inside your browser tab, so the image data never leaves your device. You can even disconnect from the network after the page has loaded.
Which image formats are supported?
You can convert between JPEG, PNG, WebP, GIF, BMP, TIFF, ICO and AVIF in any direction. Support depends only on your browser, not on a server-side plan.
Is there a file size limit?
There is no artificial limit. The practical ceiling is the memory your browser tab can allocate, so very large files may need a smaller output size on low-memory devices.
Can I control quality and file size?
Yes. For lossy formats such as JPEG, WebP and AVIF you can move the quality slider to trade file size against visual fidelity, and you can also resize the output.
