How OpenFileTools processes it
Local processing, explicit choices.
Media is read from the selected File/Blob in this browser. The media engine is lazy-loaded only on these routes; OpenFileTools does not upload the source to its servers.
Questions, answered.
Is my media uploaded?
No. Source bytes remain on this device and are read directly by the browser. OpenFileTools does not receive the file.
Why can a recognized file still fail?
A container and the codecs inside it are separate. Browser decoder and encoder support varies by operating system and browser, so the tool checks the actual track rather than promising universal conversion.
Does processing change my original?
No. A separate result is created for preview or download; the selected source file is not modified.
