Slides

Slide 1 of 6

Tip: best results with 1080×1350 (4:5 portrait) or square images. Landscape photos get cropped heavily. Plain backgrounds (gradients, textures, abstract shots) work better than busy photos because the text overlays on top.
Accepts JPG, PNG, WebP up to 15MB. Auto-resized to 1080px wide JPEG.

How to design LinkedIn carousels that actually get saved

4:5 portrait outperforms square

LinkedIn's mobile feed is vertical-first. A 4:5 (1080x1350) carousel takes 25% more screen real estate than a 1:1 square, which means more scroll-stopping power and more dwell time per slide. This tool exports at 4:5 by default.

Make the cover slide do 80% of the work

Slide 1 has to stop the scroll on its own. Punchy title, clear promise, and a hint of what's inside. If the cover doesn't land, the rest of the slides never get viewed.

One idea per slide

Cramming three ideas onto a slide is the most common carousel mistake. Each slide should fit a single thought that takes 3-5 seconds to absorb. If you have more to say, make more slides.

End with a clear CTA

Save, share, follow, or comment — pick one and ask for it directly on the last slide. Carousels that ask for the save get 2-3x more saves, which is one of LinkedIn's strongest engagement signals.

Aim for 8-12 slides

Shorter than 6 slides feels thin. Longer than 12 loses people. 8-10 is the sweet spot for completion rate and engagement.

Frequently asked questions

What's the best LinkedIn carousel size in 2026?+
1080 x 1350 pixels (4:5 portrait) is the highest-performing aspect ratio on LinkedIn in 2026 because it takes up more vertical screen real estate on mobile. Square (1080 x 1080) still works but loses about 25% of the visible area on mobile. This tool exports at 4:5 by default.
How do I post a carousel on LinkedIn?+
Export the carousel as a PDF from this tool, then on LinkedIn click 'Add a document' (the paperclip / document icon) in the post composer. Upload the PDF, give it a title (this also acts as the post's accessible label), and publish. LinkedIn natively renders multi-page PDFs as swipeable carousels.
How many slides should a LinkedIn carousel have?+
8-10 slides is the sweet spot for engagement and completion rate. Anything under 6 feels thin; anything over 12 loses readers. Lead with a punchy cover slide that promises a payoff, deliver the payoff across the middle slides (one idea per slide), and close with a clear CTA on the last slide.
Does this tool add a watermark?+
No. The PDF you download is yours, no watermark, no Postbeam branding. We don't track your slides or save them — everything runs in your browser.
Can I add images to my carousel slides?+
Yes. Each slide has an optional background image upload. Drop in any JPG, PNG, or WebP and the tool automatically resizes it to 1080px wide, places it behind your slide content, and adds a readability overlay so the text stays legible. Use it for product screenshots, charts, or photos. If you want full graphic-design control beyond a background image, Figma or Canva is still the better tool.
Can I use my own brand colors?+
Yes. Pick the 'Custom' theme and you get three color pickers (background, text, accent). Paste any hex code, or use the native color swatch. The accent's text color auto-flips between white and dark for contrast as you change it. Your custom colors persist across all slides in the carousel — they're a theme, not a per-slide setting.
Why are carousels so effective on LinkedIn?+
Carousels rack up dwell time — every swipe is a signal that the algorithm treats as engagement. They also drive higher save rates than single posts, and saves are one of LinkedIn's strongest engagement signals. The result: carousels typically get 2-3x more reach than text posts in the same account.
