How to use Image converter
- Choose an image.
- Pick the output format and quality.
- Download the converted image.
What this tool does
The image converter exports browser-readable images as JPG, PNG, or WebP using the browser Canvas API. It is useful when a form rejects a format, a web page needs WebP, or a transparent graphic needs PNG.
The conversion happens locally in your browser, so the selected image is not uploaded to a conversion server by the tool.
Supported formats and output
- Input
- Images your browser can decode, such as JPG, PNG, WebP, and many common image files.
- Output
- JPG, PNG, or WebP depending on your selected format.
Practical examples
Form upload
Convert a WebP image to JPG when a school or government form only accepts JPG.
Web asset
Export a PNG or JPG as WebP for a lighter page image.
Quality considerations
- JPG quality settings affect photos strongly, especially around text and edges.
- PNG is better for sharp graphics and transparency but can be larger for photos.
Limitations
- Canvas export usually strips most metadata.
- Transparency is lost when exporting to JPG.
- Very large images can hit browser memory limits.
Frequently asked questions
Are image files uploaded?
No. The image is decoded and re-exported in your browser.
Does metadata stay in the output?
Canvas export normally strips most metadata, which can be useful for privacy.
Troubleshooting
The transparent background turned white.
Use PNG or WebP for transparency. JPG does not support transparent pixels.
The image will not open.
The browser may not support that input format. For iPhone HEIC photos, use the HEIC to JPG tool.
