How to Convert Long Images to PowerPoint
Uploading a tall image here works the same as on the PDF version of this tool, but every detected panel lands on its own slide instead of its own page — sized to fit the deck's fixed 960×540 widescreen canvas rather than taking on the panel's original proportions. PNG, JPEG, and WebP sources all work; a crisp export with solid, evenly toned gutters gives the split-point detector cleaner material to work with than a blurry photo or a noisy, over-compressed capture. A file that runs to tens of thousands of pixels can take a while to finish scanning, and on the largest images the browser may seem to freeze for a few seconds mid-detection — leave it alone until the panel count settles rather than refreshing, which would throw away any lines you've already nudged into place by hand.
Because every output slide keeps the same 16:9 shape, adjusting a split line here does something a page-based export doesn't: it changes how much blank margin surrounds that panel once it's centered on the canvas, rather than changing the page's own dimensions. Drag a line to move it, click an empty stretch of gutter to add one, or clear one with its X handle, then hit Convert once the slide-by-slide breakdown in the live preview looks right. In a section with many small panels stacked tightly, the space between two candidate lines can shrink to just a few pixels, leaving little room for error — zoom in before dragging a line so you can see exactly where one gutter ends and the next panel begins, rather than judging it from a smaller preview.
Perfect for Presentations
Converting webtoons and webcomics to PowerPoint is ideal for classroom discussions, art reviews, or sharing content in meetings. Each panel becomes a 16:9 slide, perfectly sized for projectors and screens while maintaining the original image quality. The same slide-per-panel structure works well for pitch decks that reference comic or storyboard art, competitive research decks comparing panel layouts across titles, or a walkthrough where each slide gets its own speaker notes and talking points added afterward in PowerPoint or Google Slides.
Screenshots to Slides
A scrolling screenshot — an onboarding flow, a checkout funnel, a bug reproduced across several app states — turns into one slide per screen here, each one already sized to drop into a walkthrough deck. That's a different job than the PDF version of this tool, which is built for reading a long capture top to bottom rather than presenting it screen by screen; use slides when you plan to add callouts, arrows, or speaker notes to individual steps in PowerPoint or Google Slides afterward. A screenshot packed with small, closely spaced elements — a long chat thread or a dense table — can produce many more candidate lines than an ordinary scrolling capture, because each narrow gap between rows can look like a break point; review the detected lines and clear out any that don't mark a genuine boundary, otherwise the deck ends up with far more slides than the content actually needs.
Output Format
The PowerPoint file uses standard 16:9 (widescreen) slides at 960×540 pixels. Each panel is scaled to fit within the slide while maintaining its aspect ratio, centered on the slide. Compatible with Microsoft PowerPoint, Google Slides, and LibreOffice Impress. A panel with a very different aspect ratio than 16:9 is letterboxed rather than stretched, so proportions stay correct but you'll see margin bars above and below it; keep that in mind if you're mixing tall vertical panels with wider ones in the same deck. Slide order follows the image from top to bottom, matching the original reading order. Before deleting the source, scroll through the finished deck once and pay closest attention to the panels that were nearly full-height or a very different shape from the rest — those are the ones most likely to end up heavily letterboxed or missing a hair's width along one edge if the detected boundary sat a fraction off, and nudging the split line and re-converting is simpler than cropping a slide by hand afterward.
