Chrona

Local video frame extractor

Open editor

A video frame extractor that keeps the source on your device.

Chrona is a focused browser editor for turning a local video into a useful, inspectable PNG sequence.

Supported containers

MP4, MOV, WebM, and MKV files are accepted when the current browser can decode the video track. Container support is not the same as codec support, so a file can still be rejected when its codec is unavailable.

Built for decisions, not a second video editor

Chrona focuses on the steps that change the output: trim, cut, choose a rate, choose quality, and export. You can review frame previews before downloading the ZIP.

Browser or CLI

Use the browser for a visual, local workflow. Use the Chrona CLI when you need native FFmpeg, repeatable JSON output, or filesystem streaming for a large archive.
