Safari 26.2 browser, AVIF export does not work
Author: gabortordaCreated Jan 14, 2026Updated Jan 14, 2026
When selecting AVIF as a Compress setting, the download button is just spinning. I am using the online version here: https://squoosh.app/editor
Error message in Safari console: worker.js onmessage() captured an uncaught exception: RuntimeError: Out of bounds memory access (evaluating '_e.tlsInitFunctionse')
Expected behavior When selecting AVIF as an export method, the download button should appear
Version:
- OS w/ version: OSX Sonoma 14.8.3
- Browser w/ version: Safari 26.2
