Frequently asked questions
Is ClipShrink really free?
Yes! You get 5 free compressions per day with all 4 presets and all output formats, for files up to 500 MB. Pro ($3/month) unlocks unlimited compressions, removes the file size limit, and provides an ad-free experience.
Do my videos get uploaded to a server?
Never. ClipShrink uses FFmpeg compiled to WebAssembly, which runs entirely in your browser. Your video files never leave your device — no upload, no server processing, no cloud storage. This is the safest way to compress videos.
What video formats are supported?
ClipShrink supports MP4, MOV, WebM, AVI, and MKV input formats. All output formats (MP4, WebM, MOV, MKV) are available for free. All compressed videos use H.264 encoding for maximum compatibility.
How much can ClipShrink reduce my video size?
Typical compression ratios range from 40% to 80% reduction depending on the preset and source video. The Email preset can reduce a 100 MB video to under 10 MB. The Social Media preset targets under 25 MB.
Why is compression slow in my browser?
Video compression is computationally intensive. ClipShrink uses your device's CPU via WebAssembly, which is slower than native desktop software but much faster than uploading to a server. Processing time depends on video length and your device speed.
Can I compress videos on my phone?
Yes! ClipShrink works on modern mobile browsers (Chrome, Safari, Firefox). However, video compression is CPU-intensive, so processing may be slower on mobile devices compared to desktop.
