Frequently Asked Questions
Is my video uploaded anywhere?
No. Trimming and GIF conversion both run locally in your browser using FFmpeg compiled to WebAssembly. Your video never leaves your device.
What video formats are supported?
You can drop in MP4, MOV, WebM, MKV, and most other formats your browser can decode. Trimmed clips export in the same format as your source file.
How does the GIF export work?
The trimmed range is resampled to 12fps and scaled to 480px wide with high-quality Lanczos scaling, a good balance of smooth motion and reasonable file size.
Is there a length or file size limit?
No hard limit, but very large files will take longer to process since everything runs on your own device's CPU rather than a server.
