Why? Keeping in mind that you can (and arguably should) already specify the mimetype when you create a blob. Both BlobBuilder.getBlob and Blob.slice lets you specify a mimetype. And when you get a Blob from XHR or <canvas> it should already have the correct mimetype. Additionally you can always create a new blob with whatever mimetype you want by doing: bb = new BlobBuilder; bb.append(myblob); blobwithnewmimetype = bb.getBlob(somemimetype); Or if we make BlobBuilder.append return the BuilbBuilder it'll just be blobwithnewmimetype = (new BlobBuilder).append(myblob).getBlob(somemimetype); / Jonas
