> Quick answer: Facebook Feed ads need at least 1440×1440 px (square) or 1440×1800 px (vertical). Use AI Upscale in Coinis Revise to hit that target from almost any starting image. Export as JPG or PNG and you're done.

Why Low-Res Images Don't Work on Facebook
Bad resolution kills ad performance before your audience reads a single word of copy.
The 600-pixel minimum isn't enough
Per the Facebook Ads Guide, Meta sets a minimum width of 600 pixels for Feed ads. That bar is low. Images at or near 600px look soft on modern high-density screens. Passing the minimum does not mean looking sharp.
Pixelation and blurriness hurt ad performance
Low DPI and heavy compression create jagged edges, blurry text, and lost detail. These problems appear even when an image technically clears the minimum width. Poor visuals erode trust. Clicks drop.
Meta's recommended spec: 1440×1440 or 1440×1800
The Facebook Ads Guide recommends 1440×1440 pixels for square (1:1) ads and 1440×1800 pixels for vertical (4:5) ads on Facebook Feed. Those numbers deliver sharp visuals on every device. That is the real target.

The Upscaling Solution
Upscaling is the fastest path from a small image to a Facebook-ready creative.
What upscaling does (adds detail, recovers sharpness)
Upscaling increases pixel count. But the method matters. Simple resizing just stretches existing pixels. You get the same blur, only larger. AI-powered upscaling is different. It analyzes the image content and generates new detail, rebuilding sharpness rather than expanding softness.
AI-powered upscaling vs. simple resizing
A basic resize in a standard photo editor creates visible artifacts and soft edges. AI Upscale in Coinis Revise uses cutting-edge AI models trained on image data. It rebuilds edges, recovers texture, and sharpens fine detail. The result looks like a higher-quality original, not a stretched copy.
How much to upscale: aiming for 1440 pixels on the long edge
Target 1440 pixels on the long edge for Facebook Feed. A 2x to 4x upscale hits that range for most starting images. Beyond 4x, quality gains plateau fast. At that point, regenerating the creative makes more sense.

Step-by-Step: Upscale Your Image for Facebook
Four steps. No design tools required.
Step 1: Assess your starting image resolution
Check your image dimensions before doing anything. Right-click the file and view properties, or open it in any image viewer. Note width and height in pixels. If the long edge is 300px or above, AI Upscale can do the job. Below 300px, skip to the regenerate section at the bottom.
Step 2: Use AI Upscale to enhance to 1440px minimum
Open Coinis Revise and upload your image. Select AI Upscale. Set your target output size to reach 1440px on the long edge. Coinis applies cutting-edge AI models to add detail and sharpen the result. One click.
Step 3: Verify aspect ratio (1.91:1 to 4:5)
Per Meta's Best Practices for Aspect Ratios, Facebook tolerates a ±3% deviation from the declared ratio. Upscaling preserves your original aspect ratio. Confirm the final image lands between 1.91:1 (wide landscape) and 4:5 (vertical mobile). Crop lightly if needed.
Step 4: Export as JPG or PNG and upload
Facebook Feed ads accept JPG and PNG files up to 30MB. Export from Coinis Revise in either format. Upload in Ads Manager. Your image now meets Meta's recommended spec.

Pro Tips for Best Results
Start with the highest-quality source available
Find the original file before upscaling. A 900px source upscaled to 1440px beats a 400px source every time. A better input always improves output quality.
Avoid excessive upscaling (2-4x is the sweet spot)
2x to 4x produces the best results for most images. Higher multipliers deliver diminishing returns. The AI cannot invent detail that was never there.
Check the preview before uploading to Facebook
Zoom into the upscaled image at 100% before exporting. Look for soft edges or artifacts around text and fine lines. If quality is not clean, try a lower multiplier or regenerate the creative.
Use Coinis Image Ads to auto-generate from product URLs if starting from scratch
No usable source image. Skip upscaling entirely. Coinis Image Ads generates Facebook-ready creatives from a product URL. No starting image required.

When to Regenerate Instead of Upscale
Some images are too far gone. Knowing when to stop saves time.
Extremely low resolution (<300px on long edge)
Below 300px, AI upscaling cannot recover enough detail to hit Facebook's recommended spec cleanly. The starting information simply is not there. Regenerate instead.
Severely compressed or degraded images
Heavy JPEG compression creates blocky artifacts throughout the image. AI Upscale can sharpen edges, but it cannot remove compression blocks reliably. If your image has been saved at low quality multiple times, start fresh.
Using Coinis Image Ads or Ad Clone for faster creative refresh
Coinis Image Ads generates new, Facebook-ready creatives from a product URL. Ad Clone recreates an existing ad concept from scratch. Both deliver output at the correct resolution and aspect ratio with no upscaling step needed.

Frequently Asked Questions
What resolution does Facebook recommend for Feed ad images?
Meta recommends 1440×1440 pixels for square (1:1) ads and 1440×1800 pixels for vertical (4:5) ads on Facebook Feed. The minimum width is 600 pixels, but images at that size often look soft on high-density screens.
Will upscaling a low-res image actually improve quality?
AI-powered upscaling recovers sharpness and rebuilds edge detail rather than just stretching pixels. A 2x to 4x upscale with AI Upscale in Coinis Revise typically produces a clean result. Simple resizing in a standard photo editor does not, as it only expands the existing blur.
When should I regenerate instead of upscale?
Regenerate when your source image is below 300px on the long edge or has heavy compression artifacts. AI upscaling cannot create detail that was never in the original file. Coinis Image Ads or Ad Clone can generate a fresh, Facebook-ready creative from a product URL.
What file formats does Facebook accept for image ads?
Facebook Feed ads accept JPG and PNG files with a maximum file size of 30MB. Coinis Revise exports in both formats after upscaling.
