    Choose any MP4, WebM or MOV file you own. It is opened in your browser and is not uploaded anywhere.

  2. 2

    Draw a box over the subtitles

    Click and drag on the video to cover the burned-in text. Keep the box tight, and a little larger than the text band.

  3. 3

    Remove and download

    Click Remove, check the result, and download the full-length clean MP4 back to your device.

Subtitle removal FAQ

Quick answers about privacy, quality, supported watermarks, file limits and legality.

How do I remove hardcoded subtitles from a video for free?

Open the tool, choose your MP4, WebM or MOV file, draw a box over the subtitle band, click Remove and download the result. It is free, needs no account and runs in your browser, so there is no upload and no preview limit.

Is it legal to remove hardcoded subtitles?

Yes, if you own the video or are authorized to edit it. Localizing your own content, creating a clean master, or repurposing your own footage is generally fine. Do not use this tool to remove subtitles from third-party content to misrepresent it. This is general information, not legal advice.

Can I remove subtitles without uploading the video?

Yes. The video is processed by FFmpeg compiled to WebAssembly, running inside your browser tab. The file never leaves your device. To check, open your browser developer tools, watch the Network tab while you process a video, and confirm no request carries your file.

Will it remove subtitles that change position?

No. The delogo filter applies one fixed box to the whole video. If the text moves, changes size, or uses karaoke-style highlighting, it will not be fully removed.

Why does the area look blurry after removal?

Because the filter fills the box by blending nearby pixels. Blur shows most on detailed backgrounds and with large boxes. Draw the box as tight as possible, and expect better results on plain or softly lit backgrounds.

Is this tool free?

Yes. It is free with no daily cap, no credits and no sign-up. The practical limit is your device memory, because the video is processed locally.

Does it keep the audio?

Yes. The audio track is copied from the original video without re-encoding. Your voiceover and background music remain exactly as they were.

What video formats are supported?

MP4, WebM and MOV. For other formats such as AVI or MKV, convert to MP4 first. The output is an MP4 (H.264).

Does it work on iPhone and Android?

Yes, in modern mobile browsers, with a 100 MB file limit. Processing a long video on a phone is slow, so a laptop or desktop is better for anything beyond short clips.

What if the subtitles have a black background box?

If the subtitles are placed on a solid black bar (common in older TV broadcasts), you must draw the box to cover the entire black bar. This may leave a large blurry patch, but it is often the only way to remove the text. Alternatively, you can crop the video to remove the entire black bar.

What if the subtitles touch the absolute edge of the video?

The delogo filter requires at least a 1-pixel border of real pixels around the selected area. If the text touches the absolute edge of the video frame, the tool will automatically clamp the box to fit, which may leave a tiny sliver of the text visible. Try the Blur or Pixelate method, or crop the video slightly first.

Can I remove multiple subtitle tracks at once?

Yes, you can draw up to 6 separate boxes on the video. This is useful if you have subtitles in multiple languages stacked at the bottom of the screen.

Does removing subtitles reduce video quality?

The video is re-encoded as high-quality H.264, so there is a small generation loss, usually not visible. The filled area itself can look softer than the rest of the frame, depending on the background.

Can I use this on a Chromebook?

Yes. The tool runs entirely in your browser using WebAssembly, so it works perfectly on ChromeOS, including Chromebooks. No software installation is required.

Do I need a fast computer to use this?

A faster processor and more RAM will process the video quicker. The tool uses your device's resources. For a 5-minute clip at 1080p, a modern laptop should take less than a minute.

What is the difference between hardcoded and soft subtitles?

Hardcoded (burned-in) subtitles are permanently stitched into the video pixels and cannot be turned off. Soft subtitles are separate files (like SRT) that the video player displays. This tool is for removing hardcoded subtitles. Soft subtitles can be removed by simply turning them off in your player or editor.

What this tool can and cannot remove

The tool uses FFmpeg's delogo filter. It fills one fixed rectangle using the pixels around it. That makes it fast, private and free, and it also sets clear limits.

Which subtitle types the tool can remove
Subtitle typeResultNotes
Static subtitle at the bottomWorks wellThe best case. A fixed subtitle band is cleaned convincingly on most footage.
Multiple lines of static textWorks, with caveatsDraw the box to cover all lines. On detailed backgrounds the patch can look soft or blurry.
Semi-transparent subtitlesUsually worksDraw the box tight around it. Larger faint text leaves a visible smear.
Subtitles over a face or fine detailPoorThere is not enough surrounding detail to fill in convincingly.
Moving or karaoke-style textNot supportedThe filter fixes one box position for the whole video. Text that moves or changes size will not be removed.

Troubleshooting subtitle removal

The subtitles have a black background box

If the subtitles are placed on a solid black bar (common in older TV broadcasts), you must draw the box to cover the entire black bar. This may leave a large blurry patch, but it is often the only way to remove the text. Alternatively, you can crop the video to remove the entire black bar.

The subtitles are too close to the edge

The delogo filter needs a 1-pixel border of real video pixels around the selected box. If your subtitles touch the absolute edge of the frame, the tool will clamp the box to fit, which might leave a sliver visible. Try the Blur or Pixelate method instead, or crop the video slightly before processing.

The background behind the text is moving

If your video has a busy, moving background behind the subtitle band, the delogo filter will create a static, blurry patch over that area. It cannot track moving pixels. For the best results, ensure the text sits over a relatively static part of the video.

The video is too large to process

Long videos (over 10 minutes) or 4K recordings can exhaust your browser's memory. Use the Video Trimmer to cut the recording down to just the segment you need, or use the Video Compressor to reduce the file size.

Tips for a cleaner result

  • Keep the box tight

    A box that is only slightly larger than the subtitles gives the cleanest fill. A big box turns into a visible blur that distracts from your footage.

  • Trim first

    Cut the clip to the part you need with the Video Trimmer, and shrink big files with the Video Compressor. Shorter files process faster and use less memory.

    Video TrimmerVideo Compressor

  • Check on a busy frame

    Scrub to a frame with detailed background behind the text before you commit. If it looks soft there, it will look soft everywhere.

  • Use the original if you can

    If you edited the video, re-export it from your editor without the burned-in subtitles. That always beats any removal filter.

  • Use soft subtitles next time

    If you are creating the video, use soft subtitle tracks (SRT/VTT) instead of burning them into the video. This allows you to turn them on and off without any quality loss.

  • Multiple language tracks

    If you have subtitles stacked in multiple languages at the bottom, you can draw a single tall box to cover them all, or separate boxes for each language.

ToolDeck vs cloud AI tools

Cloud AI tools upload your video, track moving objects and regenerate the hidden area. ToolDeck trades that for privacy and no limits: nothing is uploaded, and the full download is free.

What you get for free

  • FFmpeg in your browser

    WebAssembly-powered FFmpeg processes the video on your device. No server queue and no upload. Speed depends on your device and the length of the video.

  • Draw your own selection

    Click and drag to draw a box exactly over the subtitle band. Works for burned-in captions and text overlays.

  • Edge-based fill (delogo)

    The delogo filter replaces the pixels inside your box using the pixels around it. It is fast and predictable, but it is interpolation, not AI generation.

  • High-quality re-encode

    The output is re-encoded as H.264 at high quality, so there is a small generation loss. The audio track is copied from the original untouched.

  • No preview limit, no paywall

    Download the full video, not a 5-second preview. No credits, no account and no daily cap.

  • No software install

    Works in any modern browser on Windows, Mac, Linux, ChromeOS, Android and iOS. No Photoshop or Premiere Pro required.

  • Desktop and Mobile ready

    Whether you need to localize a video for a client or clean up an old project, the tool works across devices. Mobile browsers are fully supported.

  • Preserves original audio

    Your voiceover, music, and sound effects are copied from the original file without re-encoding, keeping your audio crisp for the new language track.
