What this image format converter does
This image format converter re-encodes your pictures with the HTML canvas.toBlob API, so the work happens entirely on your computer. Nothing is sent to a server, which means it keeps working offline once the page has loaded and there is no waiting on uploads.
You can batch convert a whole folder of images in one pass and grab them individually or as a single ZIP. It is handy when an app or website only accepts certain formats, or when you want lighter WebP files for the web.
Honest notes on quality and metadata
Converting to a lossy format like JPG or WebP re-encodes the image, so the result is not pixel-identical to the original. Converting a JPG into PNG stores it losslessly but cannot recover detail already lost to earlier compression, and the tool never upscales or improves quality.
Because the conversion goes through Canvas, embedded metadata such as EXIF is dropped. When you convert from a format with transparency (PNG or WebP) into JPG, transparent areas are filled with a background color since JPG has no alpha channel.
Frequently asked questions
Is this image format converter really free?
Yes. It is completely free, with no sign-up and no watermarks. It runs in your browser, so there is nothing to install.
Are my images uploaded to a server?
No. Conversion happens locally with the Canvas API, so your files never leave your device.
Which formats can I convert between?
You can convert images online between PNG, JPG and WebP in any direction.
Can I convert many images at once?
Yes. Drag in multiple files, convert the whole batch, and download them individually or as a ZIP.
Will converting improve image quality?
No. Converting cannot add detail or upscale. Lossy targets like JPG and WebP re-encode the image, and lossless targets like PNG only preserve what is already there.
