This app is only available on the App Store for iOS devices.


PixelCalc-HD is a very convenient tool for anyone working with digital images, whether from a Camera, scanner or other input device. It is especially useful for graphic designers who work with both Web and Print media. Either of these areas of media frequently require conversions from Pixels to Inches and Inches to Pixels along with a desired Resolution (i.e. hi-res, medium-res or low-res). Want to know the approximate file size? PixelCal-HD will display file size estimates for both 8-bit and 16-bit color for any selected size and resolution.

More Stuff!
There is also a Proportional Calculator that will instantly calculate enlargements or reductions of images, photos, artwork, layouts, or any kind of design. Basically, anything that needs to be resized accurately while maintaining perfect proportions, the Proportional Calculator will do it.

Contains the following handy reference charts:
-Maximum Print Size per Megapixels (with different resolutions)
-Maximum Print Sizes (in inches) by Megapixels @ 300ppi
-Shutter Speed Chart (Useful camera tool for perfect shots!)

PixelCalc-HD is super easy to use and allows you to switch instantly from one function to the other.
