Open, view and edit PowerPoint (.pptx) presentations in your browser — preview every slide as an image-like rendering, turn on text editing to change any text box, then download the updated .pptx. Everything runs locally — your presentation is never uploaded.
100% in-browser — no upload, no account. This page reads and writes .pptx files directly in your browser. Editing covers text content (add, change or remove text in any text box); images, tables, charts and layout are preserved as-is. The legacy binary .ppt format is not supported here — for server-side conversion use the PowerPoint Converter.

PPTX — a ZIP of XML, like XLSX and DOCX
A .pptx file is the same kind of package as Excel's .xlsx and Word's .docx: a ZIP archive of XML parts under the Office Open XML standard. Each slide is its own XML part plus a relationships file pointing to its pictures; one presentation part lists the slides in order. That structure is what lets this page read, edit and re-save decks entirely in the browser.
.pptx = ZIP + XML (Office Open XML); .ppt = binary format from 1997, not supported here — convert it first with the PowerPoint Converter. A .ppsx "slide show" file is the same OOXML package, just saved to open in show mode.
