Free Online Video Tools

Trim clips and convert videos to vertical, square, portrait or widescreen formats without installing software. Processing uses FFmpeg compiled to WebAssembly and runs on your device, so your footage is never uploaded.

Choosing the right tool

I only need part of a longer video
Use the Video Trimmer. Fast mode cuts instantly without re-encoding; Precise mode gives a frame-accurate MP4.
I need a horizontal video in 9:16 for TikTok, Reels or Shorts
The Video Resizer & Compressor converts it with crop, bars or a blurred background, never stretching the picture.
My video file is too big to upload or send
Use the Video Resizer with “Keep original” shape, pick 720p and a stronger compression level. Trimming unneeded footage first helps the most.
What are the limits?
Files up to 500 MB are accepted. Browser encoding is slower than desktop software, so short clips and 720p output are fastest, especially on phones.
quick reference

Video export cheat sheet

TikTok, Reels, Shorts, Stories
Vertical 9:16, typically 1080 × 1920 (720 × 1280 also works and encodes faster).
YouTube (standard videos)
Widescreen 16:9, e.g. 1920 × 1080 or 1280 × 720.
Instagram and Facebook feed
Square 1:1 (1080 × 1080) or portrait 4:5 (1080 × 1350).
Safest file format
MP4 with H.264 video and AAC audio, which every platform and player accepts.
Horizontal footage in a vertical feed
Crop if the subject stays centered; otherwise fit with bars or a blurred background.
Trimming without quality loss
Use Fast mode (stream copy); cuts snap to keyframes. Use Precise mode for exact frames.

Recommended sizes change over time; confirm in each platform’s help center before important uploads.
