Inside the conversion

What FLUX actually changes

The decoded JPG is encoded by the browser's Canvas WebP encoder at your quality setting; the original JPEG bitstream is not reused.

Check after export: Compare faces, gradients, and fine texture at the final display size, and note that camera metadata is not carried over.
Private by default

Your file stays with your browser

FLUX does not send selected files to its own conversion server. Processing is handled locally on your device, while versioned conversion modules may be loaded securely when needed.

Compatibility

Before you start

Images are decoded and exported through Canvas on your device. EXIF and IPTC metadata are not copied to the result. Extremely large pixel dimensions can exceed a browser's available memory.

If a conversion stops: close memory-heavy tabs, try an image with smaller pixel dimensions, and confirm that the source opens with the expected colors and orientation.
