A private, offline media toolkit for Windows. Many tools in one app. No uploads, no account, no telemetry.
Slice CRC is a Windows app that bundles several media tools into a single window. Everything runs locally with a built-in media engine — your files never get uploaded anywhere, and most tools work completely offline.
It's built for people who want quick, no-nonsense media editing without throwing their files at a cloud service.
Cut songs on a real waveform. Mark multiple sections to keep or remove, drag the handles, scrub the playhead, and export one clean MP3 with seamless joins.
Keep or remove several sections, crop the frame, drop the audio — all in one export. Frame-accurate, with smart bitrate detection so quality never collapses.
Turn AVI, WMV, MKV, WebM and more into MP4 — or pull the audio out as MP3 at the bitrate you choose. Drop a file, pick the output, done.
A floating frame you place over any part of the screen. Resize it, then record just that area — with system sound and your mic — straight to MP4.
Save videos from the web as MP4 — or just the audio as MP3 — straight into your Downloads folder, ready for the cutters.
A clean, lightweight media player built into Slice. Build a playlist, shuffle and repeat, scrub frame-by-frame, and go fullscreen. Set it as your default and double-click any video or song to open it instantly.
