What This Tool Does
This tool adjusts the width and height of your image so it fits neatly into a Facebook post. It works directly in your browser, so there is no need to install any software before sharing a photo, graphic or promotional image.
Facebook automatically compresses and reframes images that do not match its preferred proportions. Resizing beforehand gives you more control over how the final post appears in the feed.
Recommended Dimensions for Facebook Posts
Facebook commonly displays feed images at around 1200 by 630 pixels, which creates a landscape shape close to a 1.91:1 aspect ratio. This size works well for shared links, photos and promotional graphics.
Square images around 1200 by 1200 pixels also display cleanly in the feed. The best choice depends on whether your image is a standalone photo or part of a link preview.
| Post Type | Suggested Size |
|---|---|
| Standard feed image | 1200 x 630 px |
| Square photo post | 1200 x 1200 px |
Aspect Ratio Considerations
Keeping the correct aspect ratio prevents Facebook from cropping important parts of your image, such as faces, logos or text overlays near the edges.
If your original photo does not match a typical feed ratio, consider which areas of the image are least important, since those edges are more likely to be trimmed during display.
How to Resize an Image for a Facebook Post
- Upload the photo or graphic you want to share.
- Enter the width and height you want, such as 1200 by 630 pixels.
- Choose whether to lock the aspect ratio.
- Preview how the resized image looks.
- Download the resized file to your device.
- Upload the file directly to your Facebook post.
Best Practices
- Keep important details away from the outer edges in case of cropping.
- Match the aspect ratio to the type of post you are creating.
- Check the preview before downloading to confirm nothing looks stretched.
- Save a copy of the original image before resizing.
- Compress the resized image afterward if the file feels too large.
Common Mistakes
- Uploading an oversized image and letting Facebook crop it automatically, which can cut off key content.
- Ignoring aspect ratio, which causes faces or text to appear stretched or squeezed.
- Resizing text-heavy graphics too small, making captions hard to read on mobile screens.
- Skipping a preview step, then discovering the layout looks different after publishing.
Conclusion
Resizing an image before posting helps it appear the way you intended, without unexpected cropping or distortion. Set the dimensions that match your post type, preview the result, then upload it to Facebook with confidence.
Frequently Asked Questions
What size should an image be for a Facebook post?
A common choice is around 1200 by 630 pixels for standard feed images, or 1200 by 1200 pixels for square photos. The right size depends on your post type.
Will resizing reduce image quality?
Resizing to a smaller size usually keeps quality intact. Enlarging a small image beyond its original resolution can make it appear softer or less sharp.
Does Facebook automatically resize images?
Yes, Facebook adjusts uploaded images to fit its layout. Resizing beforehand gives you more control over cropping and framing than letting Facebook do it automatically.
Should I keep the aspect ratio when resizing?
Keeping the original aspect ratio prevents stretching or squeezing. Only change it intentionally if you need a specific shape, such as a square post.
Can I resize an image without changing its format?
Yes, resizing only changes the width and height. The image format stays the same unless you choose to convert it separately.
What happens if my image is too large for Facebook?
Facebook will compress and resize oversized images automatically, which can lower visual quality. Resizing first helps you control the final appearance.
