About the Image Converter
The Image Converter changes an image between PNG, JPEG, and WebP. Drop in a file or browse for one, pick the target format, and download the converted image. It is made for developers, designers, and WordPress users who need a quick format change without installing software. Everything runs in your browser with the native Canvas API, so your image is never uploaded and stays private.
How it works
- Drop an image onto the box or click to browse. PNG, JPEG, and WebP are supported.
- Choose the target format. For JPEG and WebP, a quality slider appears so you can balance size and detail.
- Check the preview, the original and output sizes, and the dimensions.
- Click Download to save the converted file with the correct extension.

Frequently asked questions
Is my image uploaded anywhere?
No. The image is decoded and re-encoded in your browser with the Canvas API. Nothing is sent to a server or logged.
Why does the quality slider disappear for PNG?
PNG is a lossless format, so there is no quality setting to adjust. The slider shows only for JPEG and WebP, which are lossy and let you trade file size for detail.
What happens to transparency when I convert to JPEG?
JPEG does not support transparency. Transparent areas are filled with white before encoding, so the output has no see-through regions.
Which format should I pick?
Use PNG for graphics with sharp edges or transparency, JPEG for photos where small size matters, and WebP for a smaller file that still keeps transparency.
Is there a file size limit?
The tool sets no fixed limit. Because the work happens in your browser, very large images are bound by your device's memory and may take longer to convert.
