> Quick answer: Open Meta Ads Manager, start a campaign, choose your objective, select the Slideshow format, upload 2-15 images (PNG or JPG, minimum 1080x1080px), set duration between 5 and 15 seconds, add your headline and CTA, then publish.
What Is a Facebook Slideshow Ad?
A slideshow ad turns a series of still images into a video-like ad unit. It plays like a video but loads faster, costs less to produce, and reaches people even on slow connections.
Why use slideshow ads over static images
Static images tell one story. Slideshow ads tell several. Show product features across multiple frames, walk through a step-by-step sequence, or highlight multiple products in a single ad unit. The format gives you more storytelling room without the production cost of video.
Per Meta's Ads Guide, slideshow ads are specifically designed to reach people with limited data connections. That reach advantage matters in mobile-first markets where video ads struggle to load.
Lightweight video-like format advantage
Slideshow ads are smaller in file size than traditional video. They stream faster on low bandwidth and cost far less to produce. You only need still images. No camera, no editing software, no video team.
Image Requirements & Specifications
Getting specs right prevents auto-cropping and quality loss before you ever hit publish.
Recommended image size and resolution
Use a minimum of 1,080 x 1,080 pixels. Larger images stay sharp across all placements, from mobile feed to desktop.
Aspect ratio requirements
Facebook supports 1:1 (square) and 16:9 (landscape) for slideshow ads. Upload images at mixed sizes and Ads Manager will auto-crop everything to 1:1. Pick one ratio upfront and stay consistent across all frames.
File types and number of images
Accepted formats are PNG and JPG. You can include between 2 and 15 images per slideshow.
Step-by-Step: How to Create a Slideshow Ad
Per Meta's documentation on slideshow ad creation in Ads Manager, the full process runs through seven steps.
Step 1: Open Ads Manager and start a new campaign
Go to Meta Ads Manager. Click + Create to begin a new campaign.
Step 2: Choose your campaign objective
Select an objective that supports the slideshow format. Awareness, Traffic, Engagement, and Conversions all work. Not every objective enables every format, so confirm slideshow is available in the ad step.
Step 3: Select slideshow as your ad format
In the ad creation section, under Ad Format, choose Slideshow. This unlocks the image upload panel and timing controls.
Step 4: Upload your images
Upload between 2 and 15 images. PNG or JPG only. Keep all images at the same aspect ratio to avoid automatic cropping by Ads Manager.
Step 5: Set slideshow duration and add optional audio
Total duration runs from 5 to 15 seconds. Adjust the timing per slide to control pacing. Add audio from Facebook's free music library if your creative calls for it. Any custom audio must comply with Meta's copyright policies.
Step 6: Add headline, copy, and CTA
Write a short, direct headline. Add primary text that reinforces the visual message. Choose a CTA button that fits your objective: Shop Now, Learn More, Sign Up, or similar.
Step 7: Review and publish
Preview the ad across placements. Check the mobile preview closely since most impressions happen there. When everything looks right, click Publish.
Best Practices for Slideshow Ads
Image quality and consistency
Use consistent lighting, color grading, and visual style across all frames. Jarring visual jumps between slides hurt retention. Keep your brand palette and composition style tight throughout.
Duration and pacing recommendations
Shorter performs better for most goals. Aim for 5-8 seconds total if your message fits that window. Reserve the 10-15 second range for complex stories that need more room. Meta's creative guidance recommends leading with the brand or core offer in the very first frame.
Text overlay and copy strategy
Keep text overlays minimal. Heavy text on images can reduce delivery across placements. Let the headline and primary text fields carry the message. One clear idea per frame is enough.
