FAQ
Is Device Check really free?
Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.
Is anything I type into Device Check sent to a server?
No. Every keystroke is computed with native <video> plus canvas capture inside this page. Close the tab and your data is gone — unless you explicitly download or share it.
Which files work with Device Check?
Device Check accepts files up to 500MB. Anything bigger gets a clear message before any memory is allocated — never a silent hang.
I normally use 123apps — why switch?
If you are tired of server queues billed per minute and free exports with limits, VideoForge is the alternative: on-device segment export and native frame capture — no queues, no uploads.
How accurate is Device Check?
Everything runs on your device, so results are instant and repeatable — same inputs, same outputs, no server involved.
