11月2日的Image Comparator应用程序分析

Spot every difference between two images: before and after edits, two versions of a design, a RAW file and its export, or two shots of the same scene. Image Comparator puts two pictures on top of each other and gives you precise tools to see exactly what changed. It's built for photographers, retouchers, designers, developers and QA testers who need a real answer, not a guess. SIX WAYS TO COMPARE • Slider: drag a divider across both images, vertically or horizontally • Side by side: two panes with zoom and pan locked together • Overlay: fade image B over A with an opacity slider • Difference: highlight every changed pixel and count the changed regions • Blink (PRO): flip between A and B so changes jump out as motion • Lens (PRO): reveal image B through a round or square lens you drag around ZOOM TO THE PIXEL Pinch, double-tap or jump to 1:1. Pixel-perfect zoom keeps edges crisp, and an optional pixel grid appears at high zoom so you can inspect individual pixels. INSIGHTS • Similarity score with a plain-language verdict, from "Identical" to "Different images" • Overview of dimensions, megapixels, aspect ratio, file size and format • Camera metadata (EXIF) side by side: camera, lens, exposure, aperture, ISO, focal length and more • PRO metrics: SSIM, PSNR, mean ΔE 2000, changed pixels, MSE and perceptual-hash distance • PRO luma and RGB histograms with correlation, plus dominant color palettes ALIGN IMAGES Fit B onto A with Stretch, Contain, Cover or 1:1. PRO adds one-tap auto-align for handheld shots, plus offset, scale and rotation controls and 1-pixel nudges. SAVE & EXPORT • Save comparisons and reopen them later with all their settings • Export a side-by-side, stacked, split or current-view image as JPEG, PNG or WEBP • PRO exports: a difference map, a full comparison report, full-resolution output and extra label styles and fonts • Share straight to any app MAKE IT YOURS 8 hand-tuned themes, light and dark (4 included free), custom A/B labels, and 13 languages. PRIVATE BY DESIGN Your images are compared right on your device. The app never uploads them. Supports JPEG, PNG, WEBP, GIF, BMP, AVIF and SVG.
