Updated October 14, 2026. Written for DeckCraft 0.6.1 (what changed since).
Steps to open and re-save a .pptx
- Open the editor at easyruncraft.com/deckcraft/editor. The first visit downloads the app, about 6 MB compressed, and opens a sample deck; later visits load from the browser cache.
- Open your file. Click the Home icon and choose Open…, or drag the .pptx onto the window.
- Edit. Click into a text box to type, use the ribbon tabs as you would in PowerPoint, and add speaker notes in the area under the slide. Undo (Ctrl+Z, Cmd+Z on a Mac) steps back through your changes.
- Export a .pptx. Click the search icon at the top right, type Export and pick the Export… entry that opens a dialog. Choose PowerPoint Presentation (.pptx) and click Export. The browser downloads the file under the deck's title.
The search also lists a second Export… entry that only shows an error; ignore it. The Save icon at the top left downloads a .deckcraft file, DeckCraft's own format. It reopens here with nothing lost, but PowerPoint can't read it. The browser editor has no autosave, so export or save before you close the tab.
Which files open?
| File | Opens in DeckCraft? |
|---|---|
| .pptx presentation | Yes, and exports back as .pptx |
| .potx template, .ppsx slide show | Yes, as an ordinary presentation; the export is a plain .pptx |
| .ppt, .pot, .pps (PowerPoint 97-2003) | No |
| .pptm, .potm, .ppsm (macro-enabled) | No |
| .odp (OpenDocument) | No |
| Password-protected .pptx | No |
| .txt or .md outline | Yes, as new slides (see outline to slides) |
An old .ppt has to become a .pptx in another app first. LibreOffice Impress opens .ppt files and saves .pptx, and so does PowerPoint itself on any computer that has it. For other file types, which free app opens your file lists the extensions each Craft app reads.
What carries over from PowerPoint
DeckCraft reads and writes these parts of a .pptx, so they survive the trip in and back out:
- Slide masters, layouts and placeholders, themes with their color and font schemes, sections and speaker notes.
- About 150 preset shapes, custom shapes, groups and connectors; gradient, picture and pattern fills; outlines with dashes and arrowheads; shadows, glow, soft edges and reflections.
- Text with bullets, numbering, levels, autofit, columns, vertical and right-to-left text, fields and hyperlinks.
- Pictures with crop and color changes, tables with their styles, and charts.
- All 48 transition types, Morph and Vortex among them, and animations with their triggers and motion paths.
- Audio and video, which play when you present the deck in the browser.
What changes or gets lost
- The browser editor embeds two typefaces: Inter, in regular and bold, and BIZ UDPGothic for Japanese. Text set in Calibri, Aptos or any other font is drawn in Inter, so a title can wrap onto a second line or bullets can run past their box. Fonts embedded in the .pptx are ignored. The desktop app uses the fonts installed on your computer.
- EMF and WMF pictures, common in decks made on Windows (pasted charts, Visio drawings, logos), show as blank. For SVG icons you see the PNG copy PowerPoint stores alongside.
- The newer chart types (waterfall, funnel, treemap, sunburst, histogram, box and whisker) are not read. SmartArt opens as a group of shapes and is exported that way, so PowerPoint no longer treats it as SmartArt.
- Equations are not supported. 3-D effects and WordArt-style text warps stay in the file but are not drawn.
- The exported .pptx loses the replies and resolved state of modern comments, media playback options and the rewind setting of animations.
DeckCraft is in alpha. Its exported .pptx files open in PowerPoint without a repair prompt, but its PowerPoint support has so far been checked only on decks DeckCraft made itself, not on a collection of real-world decks. Corporate templates are where surprises turn up, so keep the original and open the export once before you send it.
Other ways to export
The same Export… dialog writes a PDF (full-page slides, notes pages, or handouts with 1, 2, 3, 4, 6 or 9 slides per page), a PNG or JPEG of the current slide, and an Outline (.txt) of every slide's title and text. The PowerPoint to PDF guide covers the print layouts. In the browser, "PNG images (all slides)" exports only the selected slide, so use the PDF to get the whole deck in one file.
To get speaker notes, a summary or a review of the deck you opened, export it as .pptx, open AI tools in the top bar and choose the Your deck tab. The AI presentation maker picks up the export and drafts notes for every slide, a review, likely audience questions or a shorter version, using EasyRunCraft credits.
