Pixels to Megapixels Calculator
Convert image width and height into total pixels and megapixels. Check photo resolution for web, print, and upload requirements.
Calculate the target first, then convert, compress, resize, or clean the image with AI when needed.
Calculate Megapixels
Calculate dimensions, compression, file size, print size, and web image budget from one set of inputs.

Current estimate is 3.54 MB for 8 images against a 1,000 KB budget.
Convert dimensions into megapixels
Megapixels help compare image resolution across cameras, uploads, and print workflows. This calculator turns width and height into total pixels and MP.
It also shows related planning data such as aspect ratio, estimated file size, and print dimensions.

Frequently asked questions
How do I calculate megapixels?
Multiply width by height, then divide by 1,000,000. A 4000 x 3000 image is 12 megapixels.
Do more megapixels mean better quality?
Not always. More pixels can capture more detail, but sharpness, lighting, compression, and editing also matter.
How many megapixels do I need for websites?
Most website images need far fewer pixels than camera originals. Resize to the display need before uploading.
Plan the image, then improve it
Use free calculators for sizing and compression decisions, then use Photo Cut tools when the image needs AI cleanup, watermark removal, logo removal, or smarter compression.
