What video formats does the trimmer support?

The video trimmer supports MP4, WebM, and MOV files. MP4 is the most widely compatible format and recommended for best results across all social media platforms.

Is there a maximum video length or file size?

The trimmer supports video files up to 500MB. There is no limit on input video length — you can trim a long video down to any duration you need.

Does trimming reduce video quality?

No. The trimmer uses copy-mode processing which preserves the original video and audio quality. It simply cuts the file at the specified start and end points without re-encoding.

Is my video uploaded to a server?

No. All processing happens entirely in your browser using FFmpeg.wasm. Your video never leaves your device, making it completely private and secure.

What are the recommended video lengths for social media?

TikTok supports up to 10 minutes but 60 seconds performs best. Instagram Reels allows up to 90 seconds. YouTube Shorts must be 60 seconds or less. Facebook Reels can be up to 90 seconds.
