About Diff All

DiffALL is a web tool for comparing two files and seeing every difference, or for measuring the quality of one file. It handles video such as MP4, AVI, MOV and MKV, audio such as MP3, WAV, FLAC and AAC, images such as JPG, PNG, WEBP and GIF, subtitles in SRT or VTT, and text, JSON, CSV and XML that can be pasted or uploaded.

Comparisons produce similarity scores and visual output such as heatmaps, with an optional synchronized side-by-side preview player, and the image comparison is described as tolerant of angle and lighting differences. Single-file checks report properties such as bitrate, focus and loudness. A voice comparison tool is linked for checking whether two recordings feature the same speaker, and an API and a What's New page are available.

DiffALL is free to use without sign-up, with a credit balance and an upgrade option shown in the interface. It suits QA teams and media engineers checking encodes, subtitle files or generated outputs.
