About AVIF → JPG
Why convert AVIF to JPG?
Email clients, older photo printers, content management systems and some social platforms reject AVIF uploads. JPG is the safest fallback — every viewer and every device renders it.
Does this work for every AVIF file?
verto relies on the browser's AVIF decoder, which is shipped by every up-to-date Chromium, Firefox and Safari. Animated AVIFs are flattened to the first frame. HDR/wide-gamut AVIF is decoded but tone-mapped down to the JPG color space.
Is anything uploaded?
No. verto is a static page. The AVIF bytes are decoded with the browser's Canvas API, re-encoded as JPG locally, and handed back to you. Closing the tab erases every file.
