Audio & video tools — trim, convert, edit

The hub for SnapToolz' audio and video tools — trimming clips, shrinking a video under a size cap, turning a moment into a GIF, or pulling the soundtrack out of a recording. This page sorts them by task so you land on the right one. Everything runs in your browser, which matters when the clip is a private voice memo or a recording you'd rather not upload anywhere.

  • No uploads — files stay on your device

Who this hub is for, and where to begin

Anyone who needs a quick edit without opening heavyweight software: shaving the dead air off a screen recording, getting a clip under a messaging app's upload limit, making a short GIF for a chat, or grabbing the audio from a video. Because the media never leaves your device, these suit private recordings — voice memos, confidential meetings, samples you don't want feeding someone's dataset.

A useful order of operations: trim first to cut only what you need, then compress if it still needs to be smaller. Just need the sound? Audio Extract pulls it out; a short animation? Video to GIF. The trade-off is speed — a browser encode is slower than a desktop one — which each tool page explains alongside its codec and bitrate options.

Frequently asked questions

  • Why is the output WAV instead of MP3?

    WAV (16-bit PCM) requires no codec license and is guaranteed lossless — perfect for trims you'll pass to another editor. If you need MP3 specifically, encode the WAV with any audio app afterwards.

  • Will my audio quality drop?

    No. The trim is a sample-accurate slice of the decoded buffer, with a 5 ms equal-power fade at each end to prevent clicks.

  • Why edit audio in a browser instead of Audacity?

    Audacity is more powerful and the right pick for multi-track editing, effects chains, or noise reduction. The browser-only Audio Trimmer is for the common quick case: drop a file, trim it, download. No install, works on phones, runs offline. For a 30-second trim before sharing a voice note, the browser path is faster.

  • Are my files uploaded anywhere?

    No. Every SnapToolz tool runs entirely in your browser using JavaScript and WebAssembly. Files are read locally, processed in memory, and the result is offered as a download. There is no backend.

  • Is everything free?

    Yes — every tool in this category and on the entire site is free with no sign-up, no daily limit, and no watermark.
