Supported formats: Any Image · Processing: 100% browser-local HTML5 Canvas & Blob APIs
How to use Image Dimension Checker
- Drop or select any image file to view instant source telemetry right below the preview.
- Review exact pixel width × height, simplified aspect ratio, megapixels, orientation, and byte size.
- Optionally adjust output format and quality to test how much file size can be saved, then click Analyze & Export.
Practical use cases
- Verifying whether an image meets exact pixel width, height, and KB requirements before uploading to a strict portal.
- Checking aspect ratios (such as 16:9, 4:3, or 35:45) and bits-per-pixel compression efficiency.
Common problems & solutions
Problem: My file meets the KB limit, but a form still rejects its dimensions.
Solution: Check the "Source dimensions" readout—many portals require an exact pixel width and height (e.g., 413 × 531 px) in addition to a KB limit.
