SUB&SUB Tools

SUB&SUB desktop toolbox: full-page scrolling screenshots, badge stamping, expiring share links. More tools on the way.

SUB&SUB Tools is the desktop companion extension for tools.subnsub.com. It ships with its first tool — full-page long screenshots — and more tools will join over time. [Full-page long screenshots] • Finds what actually scrolls: surveys every scrollable container, test-scrolls each candidate, and captures the region with the longest real travel — consoles and doc sites where the document stands still while an inner panel scrolls come out complete • Expands up to 3 independently scrolling panes (such as a right-hand parameter rail), each scrolled to its own bottom and merged into the same stitched image • Fixed navigation, sticky toolbars and back-to-top buttons are handled automatically — no repeated tiling down the image — and restored untouched afterwards • Lazy-loaded images are warmed up first, so no blank slots • Native-resolution output: the stitching scale is measured from the first frame, so HiDPI screens, browser zoom and fractional DPI all stay sharp • Three modes: full page (Alt+Shift+S), visible area (Alt+Shift+V), pick an element — press Esc during capture to cancel [Export & share] • Download PNG / save JPG / one-click copy to the clipboard • Optional subnsub corner badge: position, size and tone adjustable, composited only at the moment of export — the original stays untouched • Upload to get a share link that expires after 5/10/15/30 minutes — it cannot be extended or revoked, and stops working the moment time is up • The link is copied automatically once the upload lands [Privacy] Screenshots are produced entirely inside your browser. Only when you press "Share link" does that one image upload to tools.subnsub.com as a guest; the link becomes inaccessible at the chosen time, and the underlying file is physically cleared by the storage lifecycle within about a day. No analytics, no ads, no tracking — the same principle as the site itself.
