About the PowerPoint to JPG (Slides to Images)

Choose a PowerPoint presentation (.pptx, .ppsx or .potx) and get every slide, or the slides you pick, as a JPG or PNG picture — for Instagram carousels, WhatsApp, a website, a thumbnail or a video editor. Pick 720p, 1080p, 1440p or 4K (the shorter side of the picture, so a 16:9 slide at 1080p is 1,920 × 1,080 pixels) or type any width, and the pictures keep the shape of your slides.

The slides are laid out on your device with the same reader as our Office Document Viewer: theme colours and fonts, layouts and masters, pictures cropped as in the deck, tables, charts redrawn from the values saved in the file, and SmartArt as PowerPoint saved it. Nothing is uploaded. Without a pass, the free preview shows the first slide pictures at reduced size with a MySmartCoPilot watermark, and the size of every picture; with a pass, or after unlocking this result, you get each full picture or one ZIP named slide-01, slide-02 and so on.

Common uses

• Posting a presentation as an image carousel on Instagram or LinkedIn, or slide by slide on WhatsApp.
• Putting slides into a video editor, a document or a website that does not take .pptx files.
• Making thumbnails or cover pictures from a title slide.
• Saving a diagram drawn in PowerPoint as a transparent PNG.

Sizes in pixels

The presets name the shorter side of the picture, as video sizes do: 720p, 1080p, 1440p and 2160p (4K). A widescreen 16:9 slide becomes 1,280 × 720, 1,920 × 1,080, 2,560 × 1,440 or 3,840 × 2,160 pixels; a 4:3 slide at 1080p is 1,440 × 1,080. With Custom width you type the width and the height follows the slide shape.

Browsers limit how large one picture may be, so each picture is kept within what yours can make: about 16.7 megapixels and 8,192 pixels a side in Safari and on phones and tablets, and 50 megapixels in other browsers on computers. A size above that is made at the largest size allowed, and the page tells you which.

How the slides are drawn

A .pptx file is a ZIP archive of XML parts (Office Open XML, ECMA-376). Each slide is read with what it inherits from its layout and master, laid out as a web page at the slide’s own size, and painted into a picture at the size you chose — so text stays sharp at 4K. The file never leaves your device, and nothing in it runs: macros and embedded objects are only noted.

Limitations

• Fonts that are not on your device are replaced with look-alikes (Calibri with Carlito or another sans-serif), so a line can break differently than in PowerPoint; the page lists the fonts it could not find.
• Animations, transitions, audio and video are left out: video shows its poster picture, and every shape is drawn where it sits on the slide.
• Pictures in EMF or WMF format (common in decks made with older Office versions) can’t be drawn by browsers and appear as labelled boxes; charts are redrawn from their saved values in a simpler style; 3-D effects and shadows are drawn flat.
• Legacy PowerPoint 97–2003 (.ppt) files and password-protected presentations are not opened: save them as an unprotected .pptx first. Some versions of Safari on iPhone and iPad can’t make pictures from slides; the page then offers PowerPoint to PDF followed by PDF to JPG.
