Practical examples and limitations
When to use this tool
Use actual pixel dimensions when choosing an image for a website, document or print. Megapixels count the total pixels, and aspect ratio describes the shape. Neither tells you whether the photo is sharp or whether a larger copy contains genuinely more detail.
Worked example
A 4000 × 3000 image contains 12,000,000 pixels, or 12 MP, with a 4:3 ratio. A 2000 × 1500 copy has 3 MP: halving each dimension leaves one quarter of the pixels. Compare the exported copy with the original to catch unexpected resizing in your workflow.
What to check before using the result
An EXIF orientation value can swap the displayed width and height. Judge landscape and portrait by the visible orientation, not solely by the stored pixel rows. An editor may upscale a file without restoring detail. For printing, use the print planner to account for cropping and the target paper ratio.
FAQ
Frequently asked questions
Is a higher resolution always better?+
More pixels allow larger output or more cropping, but suitability also depends on sharpness, compression, viewing distance, and the target screen or print size.
