“File too large to send.” Every messaging app has a limit, every email provider has a smaller one, and phone videos blow past both. The ToolBox video compressor shrinks videos by 70–90% on GPU servers — free, no watermark, up to 2 GB per file.
The three settings that matter
- Resolution: 720p is the sweet spot for phone screens; 480p if size matters more than crispness. Keep the original only for archiving.
- Compression level: Balanced for general use, Small size for sharing in chats — visually close, dramatically smaller.
- Codec: H.264 plays everywhere; H.265 is ~30% smaller but needs newer devices. WEBM is great for embedding on websites.
Need an exact size?
Open Advanced settings and type a Target size in MB — the bitrate is calculated automatically to land on it. There are also frame-rate options and a Remove audio switch that saves even more space for silent clips.
How fast is it?
Encoding runs on a GPU server, so a several-minute phone video typically finishes in well under a minute. You see a live upload progress bar, a queue position, and an ETA — then the result plays right on the page before you download.
