About this tool
Image Converter changes photos and graphics between JPG, PNG and WebP formats directly in your browser. Drop a file in, pick the target format, adjust the quality slider, and download the result — no account, no watermark.
It is useful for shrinking screenshots before uploading, switching a PNG logo to WebP for a faster site, or converting a WebP download back to JPG for a tool that does not accept it. Because the conversion uses your device's own canvas, the images never touch a server.

Frequently asked questions
Are my images uploaded anywhere?
No. Conversion runs in your browser using the HTML canvas, so the image data stays entirely on your device and nothing is sent to a server.
Which format should I choose for the web?
WebP usually gives the smallest file at similar quality and is supported by all modern browsers. Use PNG when you need lossless quality or transparency, and JPG for wide compatibility with older tools.
Does converting to JPG remove transparency?
Yes. JPG has no alpha channel, so transparent areas are flattened onto a solid background. Choose PNG or WebP if you need to keep transparency.
Is there a limit on image size?
There is no fixed limit, but very large images use more memory since everything runs locally. If a huge file feels slow, close other tabs or resize it first.
