Frequently Asked
Is there a file size limit?
Yes — 10 MB per subtitle file. That covers roughly 300,000 lines, far more than a feature film needs.
Does converting keep the styling?
Text and timing are always carried over. SRT, VTT and TXT cannot store fonts or colours, so ASS styling is flattened when you convert to them; converting back to ASS applies clean defaults.
Are the subtitles uploaded anywhere?
No. Parsing and rendering both run in your browser, so the dialogue never leaves your device.
