Image Dimensions Checker

Drop any image and get its width, height, aspect ratio, DPI, color profile, and file size. Everything runs locally — your image is never uploaded.

Useful before resizing, generating a favicon, or uploading to a platform with strict dimension rules.

We detect PNG, JPG, WebP, AVIF, GIF, and SVG natively.
