Frequently Asked Questions

Q:Is it safe to trim private voice recordings here?

Q:How does the Video-to-GIF converter work without uploading?

A:The tool plays the video in a hidden HTML5 video element, captures frames on a canvas at defined timestamps, and compiles them into a GIF locally using a lightweight script.

Q:Does the Voice Recorder require microphone permissions?

A:Yes, it requires browser microphone access to capture audio. The recording is saved directly to your local RAM and is never transmitted.
