How to use Image Resizer
Use the Image Resizer to change image dimensions for websites, ecommerce uploads, profile photos, thumbnails, banners, and social graphics. Resize before compression to avoid oversized assets and keep images closer to the dimensions where they will actually be displayed.
Step 1: Upload the source image
Start from a larger original when possible so downscales stay sharp.
Step 2: Set width and height
Enter exact pixel dimensions for avatars, product tiles, or social crops. Lock aspect ratio when you must avoid distortion.
Step 3: Download the resized file
Export and place the image in your CMS or design handoff with the size your layout expects.

Practical tips
- Upscaling small images cannot invent detail—start from a larger file when quality matters.
- Match platform specs (for example square profile vs landscape OG images).
- Compress after resize for the best size-to-quality tradeoff.
