Auto-fit to 1200×630px for Facebook
The Facebook Post Image size is 1200×630 pixels, an aspect ratio of 1.91:1. This is the recommended dimension for Feed and link posts on Facebook. 1.91:1 matches the link-preview ratio too. This tool resizes any image to exactly 1200×630px in your browser — you can zoom, reposition, and choose whether to fill the frame (cropping edges) or fit the whole image (adding whitespace), then download a perfectly-sized PNG.
To resize an image for Facebook: upload your image above, use the zoom and position sliders to frame it inside the 1200×630px area, choose Fill (to crop and fill the whole frame) or Fit (to keep the entire image with white padding), and download. The result is exactly 1200×630px — the correct Facebook Post Image size — so it uploads to Facebook without any awkward cropping. Everything happens in your browser, so your image is never uploaded to a server.
For the best Facebook Post Image: start with a high-resolution image so it stays sharp at 1200×630px, keep important content (faces, text, logos) in the center safe zone, and export as PNG for crisp edges or JPEG for smaller file size. 1.91:1 matches the link-preview ratio too. Using the exact 1.91:1 ratio prevents Facebook from auto-cropping your image in unexpected ways, which is the most common reason posts look wrong after uploading.
The Facebook Post Image should be 1200×630 pixels with a 1.91:1 aspect ratio.
A Facebook Post Image uses a 1.91:1 aspect ratio (1200×630 pixels).
Use the Fit mode in this tool to keep your entire image with white padding, or Fill mode with the position sliders to control exactly what gets cropped to the 1.91:1 frame.
