Benefits
Convert PNG, JPG, WebP, and AVIF locally with preview, batch export, and clear format guidance.
You land directly in a conversion workflow instead of a generic tab shell, so the page explains the job before you touch a setting.
Check dimensions, transparency behavior, and file size changes before you download the converted result.
Queue many files, apply shared settings, override a selected item when needed, and download a ZIP archive when the run is done.
Tradeoffs
PNG is not always better than JPG, and AVIF is not always the right answer. Match the format to the destination instead of chasing a single default.
Changing codecs alters compatibility, alpha handling, and compression behavior. It does not restore detail that was never in the source file.
WebP and AVIF can be excellent output choices, but the product keeps capability checks visible because not every environment can encode every format.

Choose the destination format for the job at hand. PNG keeps transparency, JPG favors broad compatibility, and WebP or AVIF usually cut size further when the browser supports them.
