Image Dimensions Checker — Free Online Tool | GadgetSurge

About Image Dimensions Checker

Knowing an image's exact dimensions, file size, and format is essential before uploading to platforms with specific requirements, adding to a website, or including in a document.

This tool instantly displays all key technical properties of any uploaded image: pixel dimensions (width × height), file size, format (PNG, JPG, WebP, etc.), aspect ratio, and colour depth.

All inspection runs in your browser — images are never uploaded to any server.

How to Use Image Dimensions Checker

1. Upload your image by clicking "Upload Image".
2. The width, height, file size, format, and resolution are displayed instantly.
3. No download needed — just upload to inspect.

Common Use Cases

• Platform upload compliance: Check that images meet the dimension and file size requirements of specific platforms before uploading.
• Web performance auditing: Identify oversized images that need to be resized or compressed before use on a website.
• Design asset verification: Confirm that exported design assets have the expected dimensions and file size.
• Email attachment checking: Check image file sizes before attaching to emails to stay within size limits.

Frequently Asked Questions

What information does the checker display?

Width and height in pixels, file size in KB/MB, image format (PNG, JPG, WebP, GIF etc.), aspect ratio, and colour depth (bits per pixel).

Can I check multiple images at once?

Currently the tool checks one image at a time. Upload each image separately to check its dimensions and properties.

Is my image uploaded to a server?

No. All inspection uses browser APIs (FileReader and Canvas) and runs entirely on your device. Images never leave your browser.
