How to turn images into a PowerPoint presentation

How to turn images into a PowerPoint: the short answer

To turn images into a PowerPoint, upload the photos or screenshots (JPG, PNG, WebP or GIF) all at once, put them in the right order with the arrows in the list and click "Build and download". You get a single .pptx file with one image per slide, centered and whole, with the original size and quality preserved. The deck opens in PowerPoint, Google Slides or Keynote, ready for you to add titles and text.

1. Open the images to PowerPoint tool.
2. Select the images, JPG, PNG, WebP or GIF, all at once.
3. Put them in the order they should appear: with two or more images, each row in the list gets ↑ and ↓ arrows to move the file up or down. The first in the list becomes the first slide and sets the presentation's format.
4. Click "Build and download" (or "Build PPTX from N images" when there are several). You get a single file: with one image, it takes that image's name; with several, it is called atlasdocs-apresentacao.pptx.

What the tool does (and what it doesn't)

• One image per slide, whole and centered, with the proportions preserved: nothing is cropped or stretched.
• JPG, PNG and GIF go in exactly as they are, with no recompression: the original quality and resolution stay in the file.
• WebP is turned into PNG before going in (with no loss of detail), because PowerPoint does not open WebP.
• The slide size follows the first image, up to a limit of 13.33 × 10 inches (PowerPoint's widescreen width). Images with a different proportion get empty bands on the sides or at the top and bottom.
• Slides come out blank, with no title, text, numbering or transition: just the image.
• There are no options in the panel: no choice of slide size, background or caption. That is done afterwards, in PowerPoint.

When this shortcut is worth it

It is handy when the content is already in image form and you just need it as a presentation. Common cases: building a deck from screenshots for a tutorial, turning event photos into a recap, gathering charts exported as images, collecting scanned pages to project in a meeting, or converting comic panels. Instead of pasting image by image by hand, you do it all at once and get an editable file. If the destination is a PDF rather than slides, the guide is how to combine images into a PDF.

Tips for a well-built deck

• Put an image with the proportion you want for the presentation first: usually a horizontal one. If the first is vertical, every slide comes out vertical, and the horizontal images look small, with bands above and below.
• Prefer images of the same size and proportion: that way none gets bands and the deck looks carefully put together.
• Use images with good resolution, but do not overdo it: since JPG, PNG and GIF go in without recompression, dozens of phone photos make a heavy .pptx. If the file is too big to send, compress the photos before building.
• Check the order in the list before clicking: after downloading, reordering means working in PowerPoint.
• After downloading, open it in PowerPoint (or Google Slides) to add titles, text, numbering or transitions.

Common mistakes

• Renaming the files 01, 02, 03 and expecting the order to sort itself: the order is the one in the on-screen list. Use the arrows.
• Uploading a vertical image first by accident: the whole deck comes out vertical. Move a horizontal one to the top of the list and build again.
• Uploading PDF, HEIC, BMP or SVG: the tool accepts only JPG, PNG, WebP and GIF. Convert first with each format's own tool.
• Expecting slides with titles: they come out blank, with just the image. Text is added afterwards, in the editor.

Everything happens in your browser: your images are assembled into the .pptx on your own device and are never sent to any server.

Limit: up to 2 GB per file, with no limit on how many. With many large photos, what can run out is the browser's memory: in that case, build the deck in parts or compress the images first.

In short: turning images into a PowerPoint here means select, order with the arrows and click "Build and download". The first image sets the slide format, JPG, PNG and GIF go in untouched, and the result is an editable .pptx, with no titles, ready for your text.
