From PPT to fully editable, in three steps
Skip the desktop install. Open and edit any PowerPoint file directly in your browser.
Upload your PowerPoint
Drag and drop your .pptx file or click to browse. Files up to 100 MB are supported.
We open it in the editor
Your file is imported into the SlideSpeak editor automatically — slides, text, images, and layouts are all kept intact and ready to edit.
Edit and download
Tweak text, restyle slides, add new content, or use AI to redesign a slide. Download the result back as .pptx or PDF when you're done.
The easiest way to edit a PowerPoint online
No Microsoft Office license, no software install, no waiting on a download. Open your .pptx in the browser and start editing in seconds.
No sign-up required to start
Drop your file, open the editor, and start editing. You only need an account when you're ready to save or download — every other step is free and instant.
Safe and secure
Your PowerPoint is uploaded over an encrypted connection and never shared or used to train models. Your slides stay yours.
Why edit PowerPoint files online with SlideSpeak?

Layouts stay pixel-perfect
Slides, fonts, shapes, and images are imported faithfully so your deck looks the same in the editor as it did in PowerPoint.
AI-powered editing
Once you're in, redesign a slide, rewrite text, translate to another language, or generate brand-new slides with built-in AI.
