CleanFrame Chrome extension security report

CleanFrame is a screenshot extension for Chrome that captures full-page screenshots, scrolling screenshots, and viewport screenshots of any webpage. Save webpages as PNG, WebP, or PDF with one click. Perfect for capturing long pages, entire articles, and complete web designs. Unlike basic screen capture tools, CleanFrame uses scroll-and-stitch technology to capture entire webpages from top to bottom without gaps, duplicate headers, or missing content. The extension automatically handles sticky navigation bars, floating elements, and fixed footers that typically cause problems in full-page captures. FEATURES - Full-Page Screenshot Capture Capture entire webpages regardless of length. CleanFrame scrolls through the page, captures each section with overlapping regions, and stitches them into one seamless image. No gaps, no missing content. - Viewport Screenshot Capture only what's visible in your browser window. Ideal for quick screenshots and sharing specific sections of a page. - Scrolling Screenshot Automatically scroll and capture long pages, articles, social media feeds, and infinite scroll content. The extension handles the scrolling and stitching automatically. - Multiple Export Formats Save screenshots as PNG (lossless quality), WebP (smaller file size), or PDF (document format for printing and archiving). - Smart Fixed Element Detection Automatically detects and temporarily hides sticky headers, floating navigation, and fixed footers during capture to prevent duplicate elements appearing throughout your screenshot. - One-Click Capture Click the extension icon, select your options, and capture. Your screenshot downloads automatically with a descriptive filename including the website, dimensions, and timestamp. - Retina and HiDPI Support Screenshots are captured at your display's native resolution for sharp results on high-resolution screens. - Privacy Focused All processing happens locally in your browser.

This is a standard Chrome API. The warning appears briefly during capture and disappears when complete. Can I capture pages behind a login? Yes. CleanFrame captures whatever is visible in your browser, including authenticated pages and password-protected content. Why are sticky headers not in my full-page screenshot? CleanFrame temporarily hides fixed and sticky elements during full-page captures to prevent them from appearing multiple times throughout the image. This creates cleaner results. Is there a page length limit? CleanFrame can capture pages of virtually any length. The practical limit depends on available system memory. When should I use PDF format? PDF is ideal for printing webpages or archiving them as documents. PDFs maintain layout and are viewable on any device. What's the difference between PNG and WebP? PNG offers lossless quality with larger file sizes. WebP provides excellent quality with significantly smaller files. Choose PNG for maximum quality or WebP for easier sharing. WHY CLEANFRAME Standard screenshot tools fail on long pages. They either capture only the visible viewport or produce full-page screenshots with: - Gaps between sections - Duplicate headers and navigation bars - Missing or cut-off content - Blurry or compressed output CleanFrame solves these problems with intelligent capture technology designed specifically for modern webpages with complex layouts, sticky elements, and dynamic content. Capture clean, complete screenshots of any webpage with a single click.
