Other information

Proposal to add various output attributes on HTML's <input> elements that would allow developers to declare some conversions the browser could do to, for example, images and videos.

<input type="file" 
   accept="image/*"
   output="image/jpeg"
   outputDimensions="1:1">

Conversions can include:

• format
• size
• length
• dimensions
• compression
• possibly other things...

This is intended to address the long-tail problem and complexity of converting/editing files by deferring the problem to either the OS or the browser (instead of JS libraries, CDNs, WASM, etc., which, it is argued by those making the proposal, haven't seen adoption in the long tail).
