Facebook Post Image Resizer
Fit any photo perfectly into your Facebook posts. Support for 1:1 square, 4:5 portrait, and 16:9 landscape. No cropping, no watermarks, no signup.
✦ Stop Losing Half Your Photo to Facebook's Crop
Facebook accepts three main aspect ratios for feed posts: 1:1 square (1080×1080px), 4:5 portrait (1080×1350px), and 16:9 landscape (1920×1080px). If you upload a 3:2 portrait from your camera or a 4:3 shot from your phone, Facebook forces a heavy crop that removes critical parts of the image.
Our Facebook post image resizer solves this by extending your photo's background using Dynamic Blur — so your entire image stays visible, framed beautifully in the correct ratio. No part of your photo is sacrificed.
✦ Facebook Post Image Sizes in 2026
| Format | Aspect Ratio | Dimensions | Best For |
|---|---|---|---|
| Square Post | 1:1 | 1080 × 1080 px | Consistent grid aesthetic, product shots |
| Portrait Post | 4:5 | 1080 × 1350 px | Maximum mobile feed coverage, tall subjects |
| Landscape Post | 16:9 | 1920 × 1080 px | Widescreen scenes, panoramic shots |
| Facebook Reels | 9:16 | 1080 × 1920 px | Reels, Stories, vertical video |
| Carousel Post | 1:1 | 1080 × 1080 px | Multi-image posts, product showcases |
Facebook's recommended minimum is 1200×630px. Our tool exports at 1200px width (or 1920px for 16:9) to ensure maximum display quality after Facebook's compression.
✦ Dynamic Blur vs. Solid Color for Facebook Posts
- Dynamic Blur — Extracts the edge colors of your photo and creates a blurred natural extension of the scene. Best for travel photos, portraits, event photography, and any image where the background context matters.
- Solid Color — Fills the padding with a chosen color. Best for product photography, brand-consistent content, screenshots, and professional graphics where a clean edge is preferred.
✦ Frequently Asked Questions
What is the best size for Facebook post images?
1200×630px minimum. For the best quality, upload at 2048×2048px or wider. The 4:5 ratio (1080×1350px) gives the most visual impact in the mobile feed.
How do I post a full photo on Facebook without cropping?
Use our Dynamic Blur feature. Upload your photo, select your target ratio, and the tool extends the background naturally — preserving your entire image.
Will my Facebook post image lose quality?
Facebook always recompresses images. Starting with a 1200px-wide file at the correct aspect ratio minimizes the impact.
Can I use this for Facebook Reels covers?
Yes. Select Custom Size and enter 1080×1920px for the 9:16 Facebook Reels format.
