Clipbench: Video Toolkit

Clipbench is a complete video toolkit that runs entirely on your iPhone. Pick a video, adjust the settings, run it, then save or share. No sign-up, no uploads, no waiting on a server — and nothing you process ever leaves your device. ELEVEN TOOLS, ONE APP • Compress — shrink large videos to free up space, with control over resolution and quality • Trim — cut the start and the end, frame-exact when you need it • Convert — MP4, MOV and M4V, in H.264 or HEVC • Reverse — play any clip backwards, audio included • Mute — strip the sound out completely • Extract Audio — save the soundtrack as M4A or WAV • Add Audio — drop in music or a voiceover, looped to fit the clip • Video to GIF — turn a clip into a looping animation • Watermark — overlay your own text or logo • Subtitles — burn in captions from an SRT or VTT file • Social Export — reframe to 9:16, 4:5, 1:1 or 16:9 for Reels, TikTok, Stories and feed EVERY TOOL IS FREE Some tools are free to use, with no export limits and no watermark stamped on your video. Clipbench Pro is a one-time purchase — not a subscription — that adds batch compression, so you can select many videos and process them in a single run, More tools and removes ads. BUILT FOR PRIVACY There is no account to create and no server to upload to. Every tool is built on Apple's on-device media frameworks, which means Clipbench works in airplane mode and your footage never leaves your phone. Files are written to temporary storage and cleared as soon as you discard a result, and a Clear Cache button shows you exactly how much space it can reclaim. GOOD TO KNOW • Requires iOS 17 or later • Handles MP4, MOV and M4V. iOS itself cannot read or write MKV, AVI or WebM, so those are not offered. • Audio exports as M4A or WAV — iOS has no built-in MP3 encoder. • Reverse works best on clips under a minute. Longer clips work, but take longer to process.
