Preview on your device. Upload starts when you submit.
Editors replacing subtitles in a lesson, interview or travel clip can let AI find the lettering or paint exactly where to repair it. A 10-second video costs 4 paid credits with automatic detection or 7 with a painted mask. Previewing the source is free. For a caption on a plain background, the local box editor also exports a watermark-free MP4 for US$0.
How do I remove subtitles from a video?
To remove subtitles from a video, choose Auto detect for changing caption lines or Paint mask to target a specific overlay. The AI uses information across frames to fill the covered area. Check the result where the caption overlaps a face or the shot changes.
Choose a short video
Open a short clip in a playable MP4, M4V, MOV or WebM format. Scrub to a frame that shows the lettering and any shadow around it.
Choose how to find the captions
Auto detect searches for burned-in text across the clip. With Paint mask, brush over the lettering on a preview frame. A painted mask stays in the same position throughout the video.
Export the MP4

Can I remove subtitles from video online free?

Free local box examples
These clips show the free local box editor on one line, two lines and a title near the top. Each comparison shows the same caption area from the input and its export at the same instant. The AI modes use a different, cross-frame repair method.
One subtitle line on a lakeside walk
A narrow box covers the single line across the path. Watch the paving as the camera moves.
Two lines across a sunlit floor
The taller box clears both lines together. The shadows on the floor show where the replacement can soften texture.
A caption near the top of a café clip
The box sits above the table to cover the opening title. The plate and chairs below stay outside the repair.
What the video subtitle remover can’t fix
Automatic subtitle detection can also erase logos, signs or other visible text. A hand-painted mask limits the repair to one fixed shape, so a caption that moves outside it may remain. Neither mode can guarantee an exact reconstruction of a face, hand or pattern hidden by lettering.
AI uploads support up to 24 MiB, 120 seconds, 7,200 frames and 1920 × 1080 pixels in either orientation. Preview and paint in your browser before submitting. The free local box supports up to 100 MiB and fills its rectangle on every frame, including gaps between lines.
Video subtitle remover FAQ
AI uploads start only when you submit an edit. The project stores the video and any mask, sends their links to WaveSpeed for processing, and makes the finished file available in your account for 24 hours.
How can I tell if my subtitles are burned in?
Switch off CC or Subtitles in your player. If the text disappears, leave the track switched off. If it stays visible, it is part of the picture and you can mark it for repair.
Can I use the captions remover on my phone?
Yes. Use a mobile browser that can preview your file. Auto detect and Paint mask run on the server after you submit. The optional free local export also needs browser support for H.264 encoding with WebCodecs.
Will the MP4 keep my dialogue and music?
AI exports combine the repaired video with the original primary audio when its codec fits MP4, including AAC. If the source audio cannot be copied, the export needs a compatible audio track in the provider result. A silent source stays silent.
Can I erase Vietnamese captions or a second language?
Yes. If you searched for “công cụ xóa sub,” try Auto detect on Vietnamese lettering, including accents. For stacked bilingual lines, paint both lines if automatic detection misses one. Neither mode requires a transcript.
