Question 1

Why should I strip metadata from videos before posting?

Accepted Answer

Videos contain hidden container metadata — encoder info, software used, timestamps, and more. Some creators believe this metadata can influence how TikTok and Instagram distribute your content. Stripping it gives you a clean slate with the algorithm.

Question 2

How does video metadata stripping work?

Accepted Answer

The video is re-muxed (repackaged) in your browser using WebCodecs. This creates a fresh MP4 container with no leftover metadata from the original file, while keeping the video and audio quality identical.

Question 3

Does this reduce video quality?

Accepted Answer

No. The video and audio streams are copied directly — they are not re-encoded. The only thing that changes is the container metadata. Your video quality stays exactly the same.

Question 4

What does 'Replace with device profile' do?

Accepted Answer

For videos, replacing metadata strips the container data and renames the file to indicate the target device (iPhone 15 Pro, Samsung Galaxy S24 Ultra, or Sony A7 IV). Video containers don't support EXIF injection like images do, so stripping is the primary action.

Question 5

Is my data safe?

Accepted Answer

Yes. Everything runs 100% in your browser using WebCodecs. Your videos are never uploaded to any server. We don't see, store, or have any access to your files.

Question 6

What video formats are supported?

Accepted Answer

MP4, WebM, MOV, AVI, and MKV. The output is always MP4 (H.264) for maximum compatibility with social media platforms.

Question 7

Can I process multiple videos at once?

Accepted Answer

Yes. Drag and drop as many videos as you want. All videos are processed sequentially in your browser and can be downloaded individually or as a ZIP.

Question 8

What is the maximum file size?

Accepted Answer

Up to 500MB per video. Since processing happens in your browser, larger files will take longer and use more memory. For best results on mobile devices, keep videos under 200MB.
