+ Sell more than a single codec swap
+
+
+
+
+ One dashboard for video exports and subtitle conversions.
+FormatShift now combines the original WEBM → MP4 flow with social-ready MP4 presets and a lightweight SRT ↔ VTT subtitle utility, so the product feels closer to a creator toolkit than a commodity converter.
+
+
+
+
+
+
+
+
+ Upload limit
+ Up to MB
+ Applies to video uploads and subtitle assets.
+Retention
+ hours
+ Temporary files auto-clean so the VM stays lean.
+
+
+
+
+
+
+
+ Conversion tools
+A tighter bundle for teams that need compatibility, publishing formats, and caption assets in one place.
