Frequently Asked Questions

What is JFIF?

JFIF is JPEG data with a different container label — common from cameras, iPhones, and scanners. Many apps reject the .jfif extension despite understanding the pixels perfectly.

Why PNG output?

Lossless PNG preserves every pixel for editing at the full natural size. No JPG option exists here — for JPG output use the Convert to JPG tool instead.

Batch-rename too?

No batch mode: one file converts per run and always downloads as converted.png — rename it yourself when converting folders of .jfif one by one.

Do camera files leave the browser?

No — conversion runs locally in your browser on Canvas. Only saves touch the network — downloads are unlimited.
