🔄 Image Format Converter
Convert an image between JPEG, PNG and WebP, and from BMP or GIF (static first frame) to those formats. Every conversion is explained honestly: what is kept, what is lost, and when transparency disappears.
Runs entirely in your browser. No upload, no account, no image stored anywhere.

Choose imagesHow to use it
- Upload an image (JPEG, PNG, WebP, BMP, or GIF).
- Choose the output format and, for JPEG, a background colour and quality.
- Convert and download.
Supported formats and limitations
- JPEG output discards transparency — choose a background colour first.
- BMP and GIF inputs are converted from their first frame only; animation is not preserved.
- Converting to a lossy format cannot improve quality, and converting a lossy file to PNG does not restore lost detail.
- Canvas support for BMP and GIF varies by browser; if a file cannot be decoded, a clear error is shown.
- Limits: 20 MB per file, 100 megapixels, batch maximum 10 files where batch is offered.
Frequently asked questions
Which format should I choose?
JPEG for photographs, PNG for graphics with transparency or sharp text, WebP for the smallest modern files. The guide "JPG vs PNG vs WebP" explains the trade-offs.
Why is my animated GIF now a still image?
The browser Canvas API decodes only the first frame. Animation is not preserved by this tool, and the limitation is stated before you convert.
