How local video compression works
- Choose a local video and a platform target or custom size.
- Select MP4 or WebM; optionally resize to 1080p, 720p or 480p.
- The browser budgets bitrate from duration, encodes locally and makes bounded backup attempts if needed.
- Check size, format and duration, then sample decoding or use the backup validator. Download only after checks pass.

Video compression questions
How do I compress video for youtube?
Choose a local video, use the 100 MB target or enter a custom size, select a format and start. A result is marked successful only after size and integrity checks.
Is my video uploaded to a server?
No. Reading, encoding and validation run in your browser. Encoder assets may need an initial download. The site uses page analytics, but does not send video contents or filenames.
Can I guarantee both the file size and original quality?
Not both. Successful outputs stay below the limit, but long videos may need less detail or a lower resolution. An impossible budget or failed attempts produce an explanation, not a truncated video.
Do platform presets guarantee an accepted upload?
Suggested target for short clips: 100 MB. YouTube allows up to 256 GB or 12 hours, whichever is less; longer videos require account verification. Targets are separate from platform rules. Account, duration and codec restrictions may still apply.
Which formats and devices are supported?
Output MP4 (H.264/AAC) or WebM (VP9/Opus or backup VP8/Vorbis). Browser encoding is tried first, with a local backup where needed. Input support, memory and runtime depend on the device; HDR is not supported.
