Social Media Image Size Guide (2026)
Each social platform has specific image dimension requirements. Using the wrong size results in cropping, blurriness, or poor display. Vizua's dedicated resizers automatically apply the correct dimensions.
Platform Dimensions

Why Correct Dimensions Matter
Social media platforms compress and crop images that don't match their expected dimensions. An Instagram post uploaded at the wrong aspect ratio gets auto-cropped, potentially cutting off important content. By resizing to the exact dimensions first, you control exactly what your audience sees.
How It Works
Select the platform and post type, drop your image, and Vizua resizes it to the exact pixel dimensions. The tool preserves aspect ratio and lets you reposition the crop area before downloading. Everything runs in your browser — your images stay private.
