What this tool does
Convert an image into PNG, JPEG or WebP without uploading it to a remote service. The browser redraws the image and exports a fresh file in your selected format.
Different image formats are suited to different content. JPEG is widely used for photos, PNG is useful for lossless graphics and transparency, and WebP often provides a good balance of quality and size. Converting formats does not automatically improve an already low-quality source.
Useful for
- Create WebP copies for web publishing.
- Convert transparent graphics to PNG.
- Make a JPEG version when a destination does not accept another format.
How to use it
- Choose an image file.
- Select PNG, JPEG or WebP as the destination format.
- Adjust quality when the chosen format supports it.
- Preview and save the converted file.
Practical tips
- JPEG does not support transparency; transparent areas are filled with a background.
- Keep the original source file before conversion.
- Lossy conversion can introduce artifacts.
- Metadata is generally not preserved through browser canvas export.
Frequently asked questions
Can the tool convert HEIC?
Only if the browser can decode that source format natively. Support varies.
Which format is smallest?
It depends on the image. WebP often performs well, but simple graphics can still be efficient as PNG.
Are conversions uploaded?
No. Supported files are processed locally in your browser.
