Convert Images in Your Browser
Convert still images without sending source files anywhere. JPEG, PNG, WebP, GIF, and BMP use native browser decoding; the self-hosted AVIF codec loads only when AVIF input or output is requested.

How it works
Three steps, entirely on your device
- 1
Add a verified JPEG, PNG, WebP, AVIF, GIF, or BMP input.
- 2
Choose an available output format and settings.
- 3
Convert the batch and save the finished files.
Privacy and support
Conversion is performed locally with browser APIs and self-hosted codec assets. Output files exist only in browser memory until you download or clear them.
Supported formats
JPEG, PNG, WebP, and AVIF output are verified. GIF and BMP are input-only; animated GIF is explicitly flattened to its first frame.
Limitations
- HEIC, HEIF, and TIFF are recognized but remain unavailable because the audited decoders did not pass the required production matrix.
- JPEG output replaces transparency with your chosen background.
- Animation is not preserved.
FAQ
Frequently asked questions
Which formats can I convert?
Verified inputs are JPEG, PNG, WebP, AVIF, GIF, and BMP. Outputs are JPEG, PNG, capability-checked WebP, and AVIF where the optional codec can run.
Will conversion remove metadata?
Yes. The decoded pixels are written into a new file, so EXIF and other source metadata are not copied.
Can I convert many images at once?
Yes. Native files can use limited parallelism; AVIF work automatically runs one file at a time.
