A QUICK WALKTHROUGH
How to use this tool
- Choose a static JPEG, PNG or WebP.
- Inspect its pixel dimensions, detected format and byte counts.
- Use the related resizer or converter only if a requirement is not met.
How it works
File bytes come from the selected file. Dimensions and transparency come from decoded pixels, with display orientation applied. Decimal KB divides bytes by 1,000; binary KiB divides by 1,024. The aspect ratio is reduced using the greatest common divisor of width and height.
A practical example
Start with
400 × 300 pixels; 204,800 bytes
What to expect
Aspect ratio 4:3; decimal size 204.8 KB; binary size 200 KiB.
Important considerations
Pixel dimensions do not predict compressed size. The detected container may differ from a filename extension. This inspector does not enumerate EXIF tags or establish that GPS metadata is absent.
Static JPEG, PNG or WebP · 10 MiB · 16 megapixels. Input remains in page memory until you reset or leave. Copy and download actions are initiated by you. No tool input is sent to a processing service.
One more useful detail
Does DPI determine screen dimensions?
Screen pixel dimensions come from width and height. A print-resolution tag is a separate concern and is not changed by this inspector.
