About ScreenshotCalculator

Last updated: November 14, 2026

ScreenshotCalculator is a browser-based utility for checking arithmetic found in screenshots. It is designed for everyday tasks such as reading a receipt total, checking a sum, or working through a written numeric expression.

How it works

Choose or paste a PNG, JPG, or WEBP image. Optical character recognition runs in your browser, then the page looks for readable numeric expressions and calculates supported arithmetic locally. You can inspect the recognized text and edit the expression. Results need your review because text recognition can misread an image.

Our approach

The product aims to make simple calculations easier to inspect. The current static site does not connect to an AI service or upload images to a ScreenshotCalculator server. OCR software is loaded from a third-party content delivery network when you request image analysis.
