How to use video trimmer
- Choose a compatible file, drag it into the workbench, paste an image where supported, or use the included sample.
- Review the preview and adjust the available settings. Changes are rendered from decoded pixels, not simulated.
- Export the result. PixelForge assigns the correct MIME type, extension and dimensions.
Supported formats
Browser-decodable input; WebM output.
Real limitations
Frame-exact cuts depend on seeking precision and decoder support.
Privacy and accessibility
Media processing stays in this tab. The surrounding controls are keyboard-accessible and expose numeric inputs, but visual canvas content itself has limited screen-reader semantics.
Frequently asked questions
Does PixelForge upload my file?
No. This tool uses browser APIs and downloaded JavaScript. No media or filename is sent to PixelForge.
Why can support differ between browsers?
Image and video decoding and encoding depend on the browser, operating system and device codecs. The workbench fails clearly when the requested encoder is unavailable.
