Upload two images to spot every pixel difference. Use Verify Clean mode to confirm AI metadata removal — compare original vs. cleaned image with hash, size, and heatmap proof.
Image A — Original
Drop original or before image
JPG · PNG · WebP · AVIF · HEIC
Image B — Modified / Cleaned
Drop cleaned or after image
JPG · PNG · WebP · AVIF · HEIC
BlankAI's Image Diff Tool performs pixel-level comparison between two images entirely in your browser. Whether you're a designer checking revisions, a QA engineer running visual regression tests, or a photographer comparing edits, this tool instantly highlights every difference between two versions of an image.
Unlike screenshot comparison services that require accounts and uploads, everything runs locally using the HTML5 Canvas API. Your images never leave your device — there's nothing to upload and no privacy risk.
Side by Side
Classic split view. Both images displayed at full resolution for direct visual comparison.
Overlay
Changed pixels highlighted in red on top of the original image. Instantly spot modifications.
Slider
Drag the divider to reveal before/after. Perfect for subtle changes and metadata verification.
Heatmap
Color-coded intensity map. Brighter red = larger pixel delta. Reveals AI fingerprint modifications.
When you process an image with BlankAI's AI metadata remover, the tool strips EXIF, GPS, XMP, IPTC, and C2PA Content Credentials, then modifies the pixel fingerprint. The Image Diff tool lets you verify this removal by comparing the original and cleaned versions. A successful clean shows: (1) different SHA-256 hashes, (2) size reduction, (3) scattered pixel changes in the heatmap, and (4) zero metadata fields in Image B.
All formats processed locally in your browser. No server uploads. No account required.
Your images never leave your device. All comparison processing uses the HTML5 Canvas API and Web Crypto API — entirely client-side.
