Pixel Fixer: Design Review

Overlay designs on web pages, measure layout differences, and save review notes.

Compare your website with the design — right on the page. Pixel Fixer: Design Review helps designers, frontend developers, and QA teams spot visual differences, measure layouts, and turn findings into clear feedback. OVERLAY AND COMPARE • Place design images over a live web page. • Adjust position, scale, rotation, and opacity. • Work with multiple layers and organize them into folders. • Use Difference and other blending modes to reveal misalignment. INSPECT AND MEASURE • Check element dimensions, spacing, typography, and colors. • Use rulers, guides, and a grid to review alignment. • Inspect a page even without a design file. KEEP FEEDBACK IN CONTEXT • Attach comments to page elements or selected areas. • Add screenshots, priorities, and issue statuses. • Organize your work into projects and pages. EXPORT A CLEAR HANDOFF • Preview and export selected review notes as Markdown, JSON, or ZIP. • Include screenshots and relevant layout details. • Prepare actionable feedback for a developer or an AI coding assistant. CHECK RESOURCE LOADING • Start diagnostics manually to inspect loading errors. • Test how a layout behaves without images, web fonts, or a selected resource. OPTIONAL AI REVIEW • Request an AI review with or without a design image. • Run basic local checks before sending. • AI review sends the selected review context to the service only when you explicitly start it. Your projects, design images, and regular review notes are stored locally in your Chrome installation. Visual comparison and export do not require an account or an AI service. Free to use. No registration or personal API key required.
