About Image DPI Checker
We built imagedpichecker.com to solve a persistent frustration: checking the DPI and print size of an image should be instant, simple, and 100% private.
The Problem with Traditional DPI Tools
Before creating this website, anyone wanting to check an image's DPI faced two frustrating options:
1. Heavy Desktop Software
Opening Photoshop or InDesign just to verify a single photo's print resolution takes minutes, consumes gigabytes of RAM, and requires costly software licenses.
2. Insecure Online Converters
Most online DPI checkers secretly upload your personal or client photos to unverified third-party servers, bombard you with spammy popups, and force you to click "Check" buttons through artificial delays.
We believed there had to be a better way: an engineered, minimalist tool inspired by developer-first design systems like Vercel that runs entirely on the user's computer.
Our Solution: 100% Client-Side Engine
By leveraging modern browser standards—including the HTML5 FileReader, binary ArrayBuffer, and DataView decoders—we built a parser that extracts EXIF, JFIF, PNG pHYs, and TIFF headers in sub-millisecond speeds directly inside your browser.
Because no network transfer occurs, your images never leave your hardware. You can even paste images directly from your clipboard (Ctrl+V / ⌘V) and receive instant physical print calculations in Inches, Centimeters, and Millimeters at both Current DPI and 300 DPI.
Our Core Principles
Your confidential images, client proofs, and family photos are strictly your property. We have zero access to your uploaded files.
No artificial loading spinners, no "uploading pictures" waiting times, and no server queue delays. Results appear instantly.
Knowing raw DPI is only half the battle. We instantly show you the maximum crisp print size in Inches, CM, and MM so you never waste paper.
No hidden fees, no subscriptions, and no feature gating. A clean, beautiful utility open for everyone.
