Why do you need a Facebook post resizer online?
You’ve spent time creating a beautiful image for your Facebook page. You upload it, and Facebook crops it weirdly. Or it looks blurry. Or the text gets cut off. Frustrating, right?
That happens because Facebook uses different dimensions for different post types. If your image doesn’t match, Facebook automatically stretches or crops it – and you lose control.
That’s where a Facebook post resizer online comes in. You resize your image to the exact recommended size before uploading. Then what you see is exactly what your audience gets.
How to resize images for Facebook in 3 simple steps
- Upload your image: Drag any photo from your computer or phone into the box above. Or click to browse. We support JPG, PNG, WebP, GIF, BMP, HEIC – basically any image format.
- Pick the right size: Choose from our presets: Link post (1200x630), Square (1080x1080), Portrait (1080x1350), Story (1080x1920). Or enter a custom width and height.
- Click Resize and download: The tool instantly creates a new image with your chosen dimensions. Click the download button – it’s ready to post on Facebook.
That’s it. No sign‑up, no hidden fees, and your image never leaves your device.
What image formats can you resize?
Our Facebook post resizer online works with all major formats:
- JPG / JPEG – best for photos, small file size.
- PNG – supports transparency, good for logos and graphics.
- WebP – modern format with great compression.
- GIF – animated images (the first frame will be resized).
- BMP, TIFF, HEIC – and many more.
No matter what format you upload, the resized image is saved as a high‑quality JPG, which is perfect for Facebook.
Does resizing affect image quality?
It can, but our tool does its best to keep quality high. When you make an image smaller, it usually stays sharp. When you enlarge it, it may become blurry because we have to guess new pixels.
For best results:
- Start with an image that’s larger than your target size.
- If you need to enlarge, try to keep the same aspect ratio to avoid distortion.
- Use high‑resolution originals (e.g., photos from a camera or high‑res downloads).
Our tool uses smooth scaling algorithms to preserve clarity as much as possible.
Who should use a Facebook post resizer online?

- Social media managers – quickly prepare images for multiple clients.
- Content creators – ensure your memes, quotes, and graphics fit perfectly.

Troubleshooting common issues
My image looks stretched after resizing
That happens when your original aspect ratio (width ÷ height) is different from the target size. For example, a square image resized to a rectangle will stretch. To avoid this, use a preset that matches your original shape, or choose “Custom size” and enter dimensions that keep the same ratio. You can also crop your image first.
The resized image is blurry
If you’re enlarging a small image, it will blur. Try using a larger original. Also, avoid excessive upscaling – if you need a 1200px wide image, start with at least 1200px.
My file won’t upload
Make sure it’s an image file (JPG, PNG, etc.). If it’s very large (over 100MB), it might take a moment – be patient. Still not working? Try a different browser or compress the file first.
The download button doesn’t appear
You need to click “Resize Image” first. After resizing, the download link shows up.
