Dubb Capture

Screenshot and mark up any tab, pick colors, copy tab URLs, or download a site's favicon. Nothing about you leaves your computer.

Dubb Capture turns a screenshot into an explanation. Take a shot of any browser tab, mark up what matters, and paste it straight into an email, a chat, a ticket, or a doc. It also picks colors off any page, copies the addresses of your open tabs, and downloads a site's favicon. No account, no upload, no watermark. CAPTURE Visible area: exactly what is on your screen. Alt+Shift+D Full page: scrolls from top to bottom and stitches it into one tall image. Alt+Shift+F Region: opens with the crop tool ready, so you can drag out just the part you need. The moment a capture opens, it is already on your clipboard. A quick grab is two steps: shortcut, then paste. MARK IT UP Arrows and lines, which you can curve by dragging the dot in the middle. Rectangles, circles, freehand drawing, and an X for flagging what needs to go. Text in eleven fonts from 12 to 96 pixels, with bold, italic, and an optional background plate that keeps a label readable over a busy screenshot. A highlighter, numbered steps for walking someone through a process, and blur for hiding email addresses, names, and account numbers before you share. An Add Video placeholder for marking where a video belongs when you hand a page to a designer or an AI assistant. Every mark stays editable until you export: move it, resize it, recolor it, copy and paste it. Full undo and redo, cropping, and zoom with a trackpad pinch. PICK A COLOR A magnifier centered on your pointer shows the pixels underneath up close. Click to copy the color as HEX, RGB, or HSL. It reads the color your screen actually shows, so it works on gradients, photos, and video, not just flat backgrounds. It stays open, so you can pick a whole palette in one go. COPY ALL URLS Alt+Shift+U lists every open tab in your window, or in all windows, one per line. Delete the ones you don't want and copy the rest. DOWNLOAD A FAVICON Alt+Shift+I finds every icon a site offers: the SVG, the Apple touch icon, the sizes in its web app manifest, and /favicon.ico. Download any of them in its original format. If a page has no favicon, it tells you. THEN SEND IT Copy to clipboard puts a real PNG on your clipboard, ready to paste anywhere that accepts an image. Download PNG saves a file named after the page you captured, so a folder of screenshots tells you what each one shows without opening it. PRIVACY Nothing about you leaves your computer. There is no account, no analytics, and no tracking. Your screenshots, colors, and tab lists never leave your machine. The only network requests Dubb Capture makes are for a website's own icon files when you use Download a Favicon, and those are sent with your cookies turned off. Copy all URLs asks permission to read your tab addresses the first time you use it, and reads them only when you open it. GOOD TO KNOW Chrome blocks extensions on its own pages, including settings and the Web Store. Dubb Capture tells you when that happens instead of failing quietly. Full page capture scrolls and stitches, so a header that stays pinned to the top of the screen can repeat down the image. Some sites serve their icons from a separate host that blocks extensions. Those icons open in a new tab, ready to save with a right click. Chrome allows four default shortcuts. Capture a region and Pick a color can each be given a key in one click from the menu. On a Mac, Alt+Shift is Option+Shift. Made by Dubb.
