About Image Resolution Checker
A free, privacy-first image analyzer that works entirely in your browser.
Image Resolution Checker is a free online image analyzer built to help photographers, designers, print professionals, and developers instantly inspect the technical details of any image — without uploading a single byte to any server.
Why We Built This Tool
Checking image resolution should be simple. Yet most methods require you to install software, dig through file properties on different operating systems, or upload your files to questionable third-party servers. We believe you should be able to check resolution, DPI, print size, EXIF metadata, color profiles, and aspect ratios — all in seconds, all in your browser, all for free.
That's why we built Image Resolution Checker — a lightweight, blazing-fast image resolution checker that runs 100% client-side using the File API and Canvas API. No server processing. No uploads. No privacy compromises.
How It Works
Every analysis happens locally in your browser. When you drag and drop an image onto the tool, your browser reads the file's raw bytes — extracting pixel dimensions, EXIF metadata (including DPI, camera make/model, GPS, and more), ICC color profiles, and aspect ratio data. The results appear instantly. Your images never leave your device.
Who Is This For?
- Photographers — Check if your images meet resolution requirements for prints, clients, or stock submissions.
- Graphic Designers — Verify DPI, color profiles (sRGB, Adobe RGB, Display P3), and print size compatibility before sending files to print.
- Print Professionals — Quickly assess whether an image has sufficient resolution for specific print sizes (4x6, 8x10, A4, posters, and more).
- Web Developers — Check image dimensions and file sizes to optimize web performance and responsive images.
- Anyone — If you've ever asked "how to check resolution of image" or "how to check DPI of an image," this tool is for you.
