convert image format
This tool converts a JPG image into PNG format using your browser's built-in canvas rendering. JPG and PNG behave differently — PNG supports transparency and uses lossless compression, keeping sharp detail at a larger file size — so converting between them is a common step when preparing images for a specific platform or use case.
Converting to PNG to meet a platform's required image format.
Switching from JPG to PNG to reduce file size for faster page loading.
Converting to PNG when you need a transparent background.
This conversion preserves visual quality; format conversion itself doesn't degrade the image unless the target format uses lossy compression at a low setting.
Yes, transparent areas in the source image are preserved in the converted file.
No — the conversion happens locally in your browser using the canvas API; your image never leaves your device.
ToolBench runs this tool entirely in your browser. Your file or text is processed on your own device using JavaScript — nothing is uploaded to a server, nothing is stored, and there's no sign-up wall between you and the result. That's true of every one of the 500+ tools on this site, from PDF utilities to unit converters.
