結果概要
Add both images to unlock local pixel scores.
選擇模式
圖片比較滑桿, 並排圖片比較, 疊加圖片比較, and 高亮差異 stay in one workflow.結果概要
高亮差異 creates local pixel metrics after the visual 圖片比較 review.模式
圖片比較: slider, side-by-side, overlay, and local diff
圖片比較工具 separates visual review from computed pixel results so scores stay pending until you run 高亮差異.
圖片比較滑桿
圖片比較滑桿 helps before/after review for 圖片比較 and 比較照片.
並排圖片比較
並排圖片比較 keeps both files visible for 照片比較 and layout checks.
疊加圖片比較
疊加圖片比較 helps inspect alignment, color, crop, and spacing changes.
高亮差異
高亮差異 calculates browser-local pixel differences only after you run the local diff.
用途
圖片比較 for visual reviews that need clarity
Use the same workflow for 照片比較, AI 圖片比較, JPEG PNG 圖片壓縮比較, 臉部比較, screenshots, and product edits.
What you can do
圖片比較工具 selects two files, previews them locally, and compares them in the browser without upload, accounts, or share links.
AI 圖片比較
AI 圖片比較 means comparing generated image variants visually; this page does not claim automated AI analysis.
照片比較
照片比較 works for retouching, color edits, crops, cleanup, and before/after checks.
JPEG PNG 圖片壓縮比較
JPEG PNG 圖片壓縮比較 is supported as a review workflow for exported files, not as a compression service.
比較照片
比較照片 examples can include products, screenshots, scans, design revisions, and generated variants.
並排圖片比較
並排圖片比較 is useful for UI screenshots, visual QA, and product image revisions.
臉部比較
臉部比較 is limited to visual portrait comparison; it is not identity verification or biometric matching.
Methods
圖片比較 with visual inspection and local pixel checks
圖片比較滑桿, 疊加圖片比較, and 並排圖片比較 support human review; 高亮差異 runs local metrics only on request.
圖片比較 visual review
Use 圖片比較滑桿, 疊加圖片比較, and 並排圖片比較 when human inspection is the clearest path.
高亮差異 local metrics
高亮差異 runs after both images load, so local pixel metrics come from browser APIs.
PNG, JPG, JPEG, WebP workflow
圖片比較工具 currently accepts PNG, JPG, JPEG, WebP; unsupported image formats are not claimed.
Guide
比較圖片 and 比較照片 review in one page
Whether the task starts as 圖片比較, 比較圖片, or 比較照片, the page keeps selected files local.
比較圖片
比較圖片 can be a product edit, UI screenshot, generated variant, scan cleanup, or retouch pair.
線上圖片比較
線上圖片比較 runs in the page while selected files remain in the local browser session.
比較照片
比較照片 checks help decide whether visual inspection is enough or 高亮差異 should run.
臉部比較
臉部比較 is described as portrait image review only, with no identity or biometric claim.
Examples
圖片比較 examples
Preview before/after edits, product images, portraits, interiors, and landscape variants as 圖片比較 and 比較照片 examples.
Workflow
圖片比較 from local files to review
Choose two images, pick a mode, inspect the visible difference, and reset when the 圖片比較 check is done.
選擇圖片
Select the original and changed image from your device for 圖片比較.
選擇模式
Switch between 圖片比較滑桿, 並排圖片比較, 疊加圖片比較, and 高亮差異.
結果概要
Read file details first; pixel metrics are calculated locally after 高亮差異.
隱私
瀏覽器本機 圖片比較
圖片比較工具 is designed for browser-local checks that keep selected files in the active page session.
How image files are handled
- No server upload route for selected images.
