> Quick answer: iPhone photos shoot at a 3:4 ratio. Instagram Feed ads need 4:5. Crop to 1440×1800 pixels, export as JPG, and upload to Ads Manager. Or use Coinis Revise to resize, sharpen, and add text in one place.

Why iPhone Photos Need Adaptation for Instagram Ads
Your iPhone takes excellent photos. The problem is shape, not quality.
iPhone camera resolution vs. Instagram ad specs
iPhones shoot at 12 megapixels or higher. That produces images around 3000×4000 pixels. More than enough resolution for any Instagram ad format.
Aspect ratio mismatch: native photos are typically 3:4
3000×4000 pixels works out to a 3:4 ratio. Instagram Feed ads require 4:5. They look similar, but they are not the same. Upload a 3:4 photo without adjusting and Instagram auto-crops it. You lose control of the frame entirely.

Instagram Feed Ad Image Specifications (Meta Official)
Per Meta's Ads Guide, Instagram Feed image ads have clear technical requirements. Match them and your creative renders cleanly on every device.
Recommended size: 1440×1800 pixels (4:5 aspect ratio)
The recommended dimensions are 1440×1800 pixels at a 4:5 ratio. Build every ad toward that spec.
Minimum requirements: 500px width, 30MB max file size
The technical floor is 500px wide. Maximum file size is 30MB. iPhone photos clear both requirements without any effort.
File format: JPG or PNG
Meta accepts JPG and PNG only. iPhones save images in HEIC by default. Export as JPG from your camera app or photo editor before uploading to Ads Manager.
Why 4:5 fills mobile screens better than square
A 4:5 image claims more vertical screen space than a 1:1 square. More screen space means more attention. Square (1:1) still works in Instagram Feed, but 4:5 takes up significantly more of the mobile viewport.

Option 1: Manual Adaptation
This route works. It just takes more steps.
Step 1: Open your photo and crop to 4:5
Open in any photo editor. Set the crop ratio to 4:5. Reframe so your subject stays centered and nothing important gets cut off.
Step 2: Resize to 1440×1800 pixels
After cropping, resize to exactly 1440×1800 pixels. This matches Meta's recommended spec.
Step 3: Optimize brightness, contrast, and saturation
Instagram Feed is competitive. Boost contrast so your product pops. Flat, low-contrast images get scrolled past fast.
Step 4: Add headline or CTA text
Add text if needed. Keep it short. Meta removed the old 20% text-on-image rule, but lighter text overlays still receive better delivery.
Step 5: Export as JPG
Export at high quality. JPG at 85–90% quality keeps file size well under 30MB while preserving sharpness.

Pro Tips for iPhone Photos as Instagram Ads
Leave the safe zones clear
Keep the top 250 pixels and bottom 340 pixels free of text and logos. Instagram's mobile UI overlaps those areas. Text placed there gets covered by the caption field or profile UI. Keep your headline and CTA in the middle third.
Make your subject stand out
Avoid busy backgrounds. Your product needs to catch attention in the first half-second. High contrast works. Cluttered, muted backgrounds do not.
Limit text overlay
Aim for a headline and a CTA. That is it. Per the Meta Business Help Center, Meta removed the 20% text rule, but the algorithm still favors cleaner, more visual images. Less text generally means better reach.
Test two crops
Run a 4:5 vertical and a 1:1 square version simultaneously. Both fit Instagram Feed. Real performance data will show which shape your audience responds to.

Frequently Asked Questions
What size should an iPhone photo be for an Instagram Feed ad?
Crop and resize your photo to 1440×1800 pixels at a 4:5 aspect ratio. That is Meta's recommended size for Instagram Feed image ads. Minimum width is 500px, maximum file size is 30MB, and JPG or PNG format is required.
Do I need to convert my iPhone photo before uploading it to Instagram ads?
