No subtitle file? The auto subtitle generator writes them from the speech, lets you check them, and burns them in on the same page.

This file's own styles are used: sizes, colours, outlines, bold and italic, alignment, margins and positions. Animations, karaoke, rotation and clipping are drawn without their effect.
Making the video: 0%. Keep this tab open.
Burned-in subtitles are part of the picture, so they show everywhere: on Instagram, in a WhatsApp forward, on a TV that ignores subtitle files. Drop your video with an SRT, then pick the size, colour and position and save; the video never leaves your computer. No subtitle file yet? The auto subtitle generator writes them from the speech and burns them in on one page.
Questions
How do I add subtitles to a video permanently?
Drop the video and your SRT file above, check the preview, and save. The subtitles are drawn into every frame of the new MP4.
I don't have a subtitle file. Can it make one?
Yes. Use the auto subtitle generator: it writes subtitles from the speech, you check the lines in the editor, then burn them in or save the SRT.
Can I change how the subtitles look?
Yes: font size, colour, outline and position. ASS files keep their own colours, sizes and positions; animated effects such as karaoke are drawn as still text.
Will Instagram and TikTok show the subtitles?
Yes. They're part of the picture, so every app shows them, with no subtitle file to upload.
