Video Subtitle Removal (Region Masking)
Draw a box around the hardcoded subtitle bar at the bottom, mask it with blur, mosaic, or a solid color block, then re-export; soft subtitle tracks are dropped automatically on export
Supports MP4, WebM, MOV, and more
First, figure out: are your subtitles hardcoded or soft?
This determines how hard removal will be. The simplest test: open the video in a player like VLC or PotPlayer and check whether you can turn subtitles off in the menu — if you can, they're soft subtitles; if you can't, and they show up no matter which player you use, they're hardcoded.
Soft subtitles: a separate track, removable without any quality loss
MKV and some MP4 files store subtitles as a separate track, with no text baked into the pixels. This tool simply drops that track on export, so the resulting video never shows subtitles again, and the frame itself has no masking marks at all. This is common with movie rips and shows with multi-language subtitle tracks.
Hardcoded subtitles: burned into the frame, can only be masked or cropped out
Subtitles in videos exported from short-video platforms, screen recordings, and re-edited social clips are usually hardcoded — the text is already baked into the pixels. A browser can't reconstruct the original frame underneath the text, so the practical options are masking the subtitle area or cropping the bottom subtitle strip out of frame entirely.
Which of the three masking methods should you pick when removing subtitles?
| Masking method | Works well for | What to expect from subtitle removal |
|---|---|---|
| Black bar mask | Dark backgrounds, movie or TV clips | Fills the subtitle bar with solid black — the most thorough and easiest option. On dark frames it's barely noticeable, like adding a black letterbox bar. Pick this first when the text must be completely unreadable. |
| Mosaic mask | Complex or busy background behind the subtitles | Pixelating makes the text completely unrecognizable while keeping the rough color blocks of the frame, so it looks less jarring than a black bar. It's also more reliable than blur against a busy background — blur can leave behind readable text outlines. |
| Gaussian blur mask | Small subtitle area, natural-looking transition | The most visually soft option, blending best with the surrounding frame. But since subtitles are high-contrast text, insufficient blur strength can still leave the content readable — push the strength above 30 and review the exported result to confirm. |
Features
- Bottom subtitle area preset: upload a video and the subtitle bar is auto-framed — just fine-tune and go
- Freely adjustable selection — covers subtitles at the top, middle, or two-line bilingual layouts
- Three masking types: black bar, mosaic, and adjustable-strength Gaussian blur
- Drop the soft subtitle track — the exported file keeps only the video and audio tracks
- Audio preserved: original audio track is fully retained during processing

Frequently Asked Questions
Can this tool completely wipe out hardcoded subtitles?
No, it can't make it look like there were never any subtitles. Hardcoded subtitles are burned into the pixels, and there's no AI frame inpainting running in the browser. Instead, this tool masks the rectangular subtitle area with blur, mosaic, or a solid bar so the text is no longer readable. That's good enough for a solid-color bottom subtitle bar, or for re-editing and source material — if you need the frame completely untouched, your only option is to find the original footage without subtitles.
How do I remove soft subtitles (a subtitle track)?
Soft subtitles are a separate track that players can toggle on or off. This tool only writes the video and audio tracks on export, so the subtitle track is dropped automatically — just upload and process to get a file with no subtitle track. If the frame itself has no burned-in subtitles, you can even shrink the selection down to a tiny corner and just use the export process to strip the subtitle track.
Three masking methods — which one should you use to remove subtitles?
High-contrast text isn't really removed if you can still make out the strokes through the blur. For subtitle removal, mosaic or a black bar is recommended first — both fully break text legibility. Gaussian blur looks more natural, but you need to push the blur strength above 30 to make sure no text is readable. For movie clips with a dark background and white subtitles, a black bar blends in best.
What if the subtitles aren't at the bottom, or there are two bilingual lines?
The preset selection is just a starting point — drag and resize it freely. If the subtitles are at the top, drag the box up there; for two-line bilingual subtitles, stretch the box taller to cover both lines at once. If there's one subtitle bar at the top and another at the bottom with content you want to keep in between, process it in two passes — mask and export the top one first, then re-upload the result to mask the bottom one.
Does removing subtitles upload my video anywhere?
No. Decoding, masking, and re-encoding all happen in your own browser via WebCodecs — the video file never leaves your machine from start to finish, and no copy is ever stored on a server.
Does removing subtitles lower the video quality?
Masking requires re-encoding frame by frame, so there is some transcoding loss. The tool defaults to a fairly high bitrate, so areas outside the subtitle mask are visually indistinguishable from the original. If the source file already has a very high bitrate, the exported file may end up larger — you can run it through a video compression tool afterward to bring the size back down.
Is there a cleaner way than masking?
Yes: if the subtitles sit right at the bottom of the frame and you're fine with a slightly shorter frame, cropping that strip out is cleaner than masking — just use a video cropping tool to cut the bottom subtitle bar out of frame, and the result has no blur blocks at all. The trade-off is a changed aspect ratio, since some content at the top or bottom gets cut off.
What if I want to replace the original subtitles with a different language?
Two steps: mask and export the original subtitles here, then use "Add Subtitles to Video" to embed or burn in the new SRT/VTT subtitles. If you first need the original text, use "Extract Video Subtitles" to run speech recognition and get an SRT to translate.
Can I remove subtitles using a mobile browser?
Yes. Both iOS Safari and Android Chrome are supported — just drag the selection box on the preview frame with your finger. Mobile devices have limited processing power, so it's best to trim the video shorter or pick a lower output quality first; HD videos over 5 minutes will process slowly on a phone.
Which video formats are supported? Do I need to pay or sign up?
Supports common formats like MP4, WebM, MOV, and MKV, with MP4, WebM, or MOV as output. The tool is completely free, requires no sign-up, and has no limit on file count or duration — the only real limit is your device's performance.
