Image Format Converter
Convert between major image formats, including HEIC input and AVIF/SVG support.
Select an image and click Convert.
- HEIC/HEIF is supported as input only.
- SVG output is available only when input is SVG.
- PNG → JPG drops transparency.
Overview
Convert images between PNG, JPEG, WebP, and AVIF directly in your browser. Useful for meeting upload requirements and adopting modern, smaller formats.
How to use
- Select or drop an image file.
- Choose the output format (PNG, JPEG, WebP, or AVIF).
- Convert and download the result.
Examples
-
Modernize site images
Input: Legacy JPEG photos
Output: WebP versions that load faster at the same visual quality.
-
Meet an upload rule
Input: A WebP image for a form that only accepts JPEG
Output: A JPEG version of the same image.
Notes
- Conversion uses the Canvas API locally; files never leave your device.
- JPEG does not support transparency: transparent areas are flattened onto a background.
- AVIF output support depends on your browser; recent Chrome and Firefox versions handle it.
FAQ
- Which format should I choose for the web?
- WebP is a safe modern default. AVIF compresses even better but encoding support varies by browser. Use PNG when you need lossless quality or transparency.
- Why did my transparent PNG get a solid background?
- JPEG has no alpha channel, so transparency is flattened. Choose PNG or WebP to keep it.
- Are my images uploaded?
- No. Conversion happens entirely in your browser.
