In the browser
Open a file. Edit a slide. Keep the source.
Try OPF without setting up a project or creating an account.
The playground is a small workspace for a real presentation file.
Open local OPF JSON, edit the source or double-click slide text, and switch between source, preview or both. A slide navigator helps you move around the deck. You can format or copy the JSON and download your edited source.

"slides": [
{
"title": "Edit this sentence in the playground."
}

Try it: download this example, open the playground, choose Open JSON, then change the sentence on the slide.
The browser also offers PPTX, PDF, SVG and PNG downloads. Deck editing and conversion run locally in the browser; no deck upload is required. Autosave offers recovery after a reload.
Why it matters: less setup to try an idea, demonstrate a deck or make a quick correction. You leave with the editable source as well as the output.
