How to resize images for social media
- Use the Image Resize Tool to set exact pixel dimensions.
- Keep aspect ratio locked to avoid distortion.
- Export as JPG or WebP for photos, or PNG for graphics with text or logos.
- If the image needs a specific crop, use the Image Cropper first.
- Run the result through the Image Compressor to reduce file size before uploading.
Tips for better social media images
- Start with the largest size you need. If you are posting the same image to Instagram, Twitter, and LinkedIn, resize it separately for each platform.
- Use high-density sources. Retina screens benefit from 2x source images. If a post appears at 600px wide, export a 1200px file for sharp display on high-resolution devices.
- Check text placement. Social platforms may overlay text, icons, or profile badges on your image. Keep important content away from the edges.
- Compress without visible loss. A large PNG might be unnecessarily heavy for a social post. Use the Image Compressor to export a lighter WebP or JPG version.
Before and after
Resizing an image from its original camera resolution (e.g., 4000x3000px) down to social media dimensions can reduce file size by 80-90% before compression even begins. This makes uploads faster, saves bandwidth, and helps your content appear quickly on feeds.
FAQ
What size should Instagram posts be?
A 1:1 square at 1080x1080px works for most feed posts. Portrait posts at 1080x1350px and stories at 1080x1920px are also common.

Do social platforms resize my images?
