Under the hood

How LinksConverter works

Converter sites tend to be vague about what happens to your file after you hand it over. This page is the specific version: the four stages a job passes through, the limits that are real, and the things that will never work no matter how the link is phrased.

What happens between paste and download

  1. Stage 1

    The file arrives

    An upload goes straight from your browser to storage using a short-lived signed URL, so the file never sits on a web server waiting to be picked up. A pasted link takes a different route: a fetcher resolves it, works out what media is actually behind it, and pulls the original stream rather than a re-encoded copy from a third party.

  2. Stage 2

    It gets scanned

    Every file — uploaded or fetched — is scanned with ClamAV before anything else touches it. This runs before conversion, not after, so a malicious file never reaches a worker process or your download. Files that fail the scan are destroyed immediately and the job is failed with an explanation.

  3. Stage 3

    A worker converts it

    Conversion happens in an isolated worker process, not in the web application. Media goes through ffmpeg; downloads go through yt-dlp; documents, images and 3D meshes each have their own toolchain. Workers scale with the queue, which is why a small file usually finishes in seconds even when the site is busy.

  4. Stage 4

    You get a private link

    The result is served through a pre-signed URL that expires two hours after it is issued; until then it works for anyone who has it, so treat it like the file itself. Two hours after conversion (a day, for a job started with a Pro pass) the file is due for deletion, and a cleanup that runs every 15 minutes purges it from storage permanently — not archived, not moved to cold storage, not kept "for support purposes". There is no backup to restore from, which is exactly the point.

Limits, logging and refusals

Size and rate

Single files up to 2 GB, or 4 GB once you are signed in, which covers long and high-resolution video. Whatever comes back has to be under 2 GB, the most the virus scanner can check; a larger result is held back. Without an account you get 60 jobs an hour. No email, no watermark, and nothing you need to buy — an optional Pro pass, when offered, only raises the links-per-batch limit, and everything on this page stays free.

What we log

File contents are never logged. Request URLs are masked in server logs, so the link you paste does not sit in plain text in an access log. We keep the minimum needed to run the queue and stop abuse.

What will never work

DRM-protected streaming services — Netflix, Prime Video, Disney+ and the like — are blocked deliberately, because bypassing DRM is illegal in most countries. Private accounts, follower-only posts and paid memberships are also out of reach: if a link needs someone else’s login to view, it will not download.

Why two hours, specifically

Long enough that a slow connection, a paused download or a closed tab does not cost you the conversion. Short enough that there is no archive of other people's files sitting on a server, which is the thing that makes converter sites worth worrying about in the first place.

The trade-off is real and it cuts against us as often as it helps: if you come back the next day, the file is gone and we cannot get it back. Running the conversion again is free, so the honest answer is usually just to paste the link a second time.

If you want something removed before the two hours are up, email [email protected] with the job link and it will be purged.
