How do I download a video with SniffVid?

Copy the share link from the platform, paste it into the box on the home page and select Get Download Links. SniffVid returns every video and audio track it can find. Pick the quality you want and save it. When a platform serves audio and video separately, SniffVid merges both tracks into one MP4 in your browser.

Why does a download sometimes fail with a 403 or 410 error?

Source platforms protect their CDN links with expiring signatures. If a link is opened too late, the CDN answers with 403 Forbidden. SniffVid therefore mints media links that stay valid for fifteen minutes; after that the page asks you to parse the link again and gives you a fresh set of signed URLs.

Why is the downloaded video missing its audio?

Some platforms, YouTube in particular, serve high-definition video and audio as two separate streams. SniffVid detects this and merges them for you, but the merge only works if you pick both a video and an audio track before pressing Merge & Save MP4. If you saved a video-only stream, parse the link again and choose both tracks.

The download button opens the video instead of saving it. What should I do?

Browsers often play a file inline when they recognise the format. Right-click the download button and choose Save link as, or open the SniffVid relay link which is sent with a Content-Disposition header so the browser saves instead of plays. On iOS, open the file, tap the share icon and choose Save to Files.

Can I save a file to my iPhone or iPad?

Yes. Safari plays the merged file first, so tap the share button and pick Save to Files to store it in the Files app. If the merge itself is interrupted, keep the tab in the foreground while the progress bar moves — iOS pauses background downloads.

Is SniffVid free, and are there any limits?

SniffVid is free to use with no account and no watermark. To keep the public service healthy the parsing endpoint is rate limited, and merging very long videos depends on how much memory your browser can spare. There is no artificial daily quota on the files themselves.

Do you store the videos I download?

No. SniffVid never receives the media file. The service resolves a link, wraps the upstream address in a short-lived encrypted token and then hands it to your browser. Merging, encoding and saving all happen locally, and the temporary tokens expire within fifteen minutes.

The merged file will not open in my player. Why?

Most problems come from an interrupted merge or a codec the container cannot hold. SniffVid never re-encodes, so the tracks must already be MP4-friendly. Try parsing again, wait for the progress bar to reach one hundred percent, and open the result in a recent version of VLC, mpv or PotPlayer. If it still fails, the source stream is probably still being written upstream.

Built to be private, quick and free

Everything that touches your media happens on your own device.

Merging stays on your device

When a platform serves audio and video separately, SniffVid muxes them into a single MP4 inside your browser instead of on a server.

Every quality, clearly labelled

Each track lists its resolution, codec, container and file size, so you can weigh picture quality against mobile data.

Short-lived media links

Every media URL is wrapped in an encrypted token that expires in fifteen minutes, so links cannot be reshared or hot-linked later.

No watermark, no re-encode

Tracks are copied bit-for-bit, so nothing is stamped onto your file and the picture you get is the picture the platform served.

Nothing to install

No extension, no desktop app and no account. If your browser can play video, it can save video.

Fast on mobile too

The layout is built for one-handed use, with large tap targets and progress that keeps working while the screen is off.

What you get, in every situation

Platforms hand over their media in different ways. SniffVid adapts instead of failing quietly.

When a download may not work

SniffVid resolves public links only. Being upfront about the edges saves you a confusing failure.

If a link fails, it usually means the source never exposed a readable stream. Parsing also relies on third-party services whose behaviour can change without notice.

What SniffVid is

SniffVid is a small, independent tool that turns a public video link into a file you actually own. There is no account to create, no extension to install and no software to update — the whole thing runs in the browser tab you already have open.

Resolving the link happens on Cloudflare Workers, an encrypted token keeps the media address alive for fifteen minutes, and merging runs on your own device. Nothing you download is stored, queued or re-encoded on our side.
