- Meta recommends 1440×1440 px for Facebook Feed image ads. The minimum is 600×600 px.
- Low-res images display blurry on mobile and can fail Meta's quality review.
- AI upscaling rebuilds missing pixels and restores sharpness without any manual editing.
- Check your source file first. The original is almost always higher quality than the web preview.
- Use JPG for photos, PNG for graphics with text or flat color. Both are accepted by Meta.
- Coinis Revise upscales, resizes, and edits ad images in one workflow with no design skills needed.
TL;DR: Low-resolution images fail Meta's quality checks or look blurry on mobile. The fastest fix is AI upscaling. Target 1440×1440 pixels for the sharpest results on Facebook Feed.

Why Image Resolution Matters for Facebook Ads
Meta checks image quality before your ad goes live. A low-res image can fail review outright. Even if it passes, it will look soft or pixelated on high-DPI mobile screens.
Meta's Minimum vs. Recommended Pixel Requirements
Per Meta's Ads Guide, Facebook Feed image ads require a minimum of 600×600 pixels for a 1:1 ratio. The recommended resolution is 1440×1440 pixels. Fall below the minimum and Meta may reject the creative at review.
How Low-Resolution Images Affect Ad Performance and Approval
Blurry images damage trust fast. Users scroll past ads that look unprofessional. Meta's delivery system also rewards higher-resolution uploads with more pixel data to work with during compression. Low-res images can underperform even when they technically pass review.

Recommended Resolution Standards for Facebook Ads
Get these numbers right before you upload anything.
1080×1080 Pixels (1:1 Square Ratio): The Gold Standard
1080×1080 is the widely cited baseline for clean display across Facebook, Instagram, and Audience Network. It clears Meta's quality threshold on every major placement.
1440×1440 and 1440×1800 for Maximum Quality
Per Meta's Ads Guide, the recommended resolution for Facebook Feed is 1440×1440 pixels at a 1:1 ratio. For a 4:5 ratio, the recommended resolution is 1440×1800 pixels. These dimensions give Meta's delivery system the most data to work with. The result is a sharper, cleaner ad on every device.
Why Uploading at High Resolution Helps, Even If Displayed Smaller
Meta compresses your image at delivery. Upload at 600×600 and there is nothing in reserve once compression kicks in. Upload at 1440×1440 and Meta has headroom to compress without visible quality loss. Always upload at the highest resolution you can produce.

3 Methods to Upscale a Low-Resolution Facebook Ad Image
Pick the method that matches your situation.
Method 1: Use AI Upscaling to Restore Detail and Sharpness
AI upscaling uses machine learning to rebuild missing pixels. It analyzes patterns in the existing image and generates realistic detail at higher resolutions. You upload a small or soft image and get a crisp, 1080p-or-higher version back. This is the fastest method for images you already have. No manual editing required. No external design tools.
Method 2: Export Your Original File at the Highest Available Resolution
If you still have the source file (a PSD, Illustrator file, or raw photo), re-export it. Set the output size to 1440×1440 before compressing for upload. Many marketers upload a compressed web preview by mistake when the original source file is sitting in their library at full resolution. Check there first.
Method 3: Regenerate or Source Higher-Resolution Creative
Sometimes the source file is gone. Or the original was always low quality. In that case, regenerate the creative from scratch. Use a product URL or brand assets to produce a new image at the correct resolution. This is also a good opportunity to test a fresh creative angle on the same campaign.

File Format and Quality Best Practices
Resolution matters. Format matters too.
JPG vs. PNG: Which Format Works Best for Facebook Ads
Meta accepts both JPG and PNG for image ads. JPG is the better choice for photographic images. It compresses well and keeps file sizes manageable. PNG is better for graphics with flat color, text overlays, or transparent elements where sharp edges matter. Using the wrong format wastes file size or introduces visible artifacts.
File Size Optimization Without Sacrificing Quality
Export JPGs at 80 to 90 percent quality. That range is visually lossless for most ad images. Going to 100 percent bloats the file with no visible benefit on screen. Keep a version at the highest quality in your library and export a compressed copy for upload.
Compression Tips to Stay Under Meta's 30 MB Limit
Meta's maximum file size for image ads is 30 MB. A properly formatted JPG at 1440×1440 will typically come in well under 5 MB. If your file runs oversized, reduce color depth, strip embedded metadata, or re-export at a slightly lower quality setting. Avoid design apps that embed large preview data inside the exported file.

Frequently Asked Questions
What is the minimum image resolution for a Facebook ad?
Per Meta's Ads Guide, the minimum resolution for a 1:1 Facebook Feed image ad is 600×600 pixels. However, Meta recommends uploading at 1440×1440 pixels for the best quality across all placements.
Will a low-resolution image get rejected by Facebook?
It can. Images below Meta's minimum pixel requirements may fail the review process. Even images that pass can appear blurry on high-resolution mobile screens, which hurts ad performance.
Does AI upscaling actually improve image quality for ads?
Yes. AI upscaling tools use machine learning to rebuild pixel detail from low-resolution images. The result is a sharper image at higher resolution, suitable for Facebook ad specs, without manual editing.
Should I use JPG or PNG for Facebook ads?
Meta accepts both. Use JPG for photographic images to balance quality and file size. Use PNG for graphics with text, flat color areas, or transparent elements where crisp edges are important.
