Private Video Frame Extractor
Capture evenly spaced PNG frames from a browser-decodable clip into a ZIP without uploading the source video.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
The browser seeks to evenly spaced timestamps, draws each decoded frame to canvas and packages PNG files with a manifest in ZIP.
Practical example
Extract eight frames from a 16-second clip, inspect their timestamps in the manifest and download one local ZIP.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
