Avoid Distortion
Keep aspect ratio locked unless you intentionally need stretched artwork or fixed banner dimensions for ad placements.
Image Resizer
Resize PNG, JPG, GIF, and WebP images to exact dimensions while keeping the original file local to your browser.
Image Tools
Upload an image to preview the resized output and export it.
Use Presets as Starting Points
Use 1200x628 for social previews, small square sizes for avatars, and icon sizes only after exporting the main source cleanly.
Resize Before Uploading
For websites, resize first and then convert to the most efficient format instead of shipping oversized originals to the browser.
