BlooSnap 作者: Blooshoo

Take a screenshot of an entire web page, however long, then mark it up before you share it. Free and open source (MIT).

Capture
~ One click (or Alt+Shift+S) scrolls the page and stitches it into a single image
~ Handles sticky headers, fixed footers, lazy-loaded images, scrollable panels (like email), and same-site iframes
~ Giant pages are split cleanly instead of failing

~!~!~!Edit~!~!~
~ Crop
~ Redact: black out or pixelate private info (it's flattened into the image, so it can't be undone)
~ Arrows, rectangles, highlights, text in several fonts, and searchable emoji
~ Click anything to move, resize, recolor, or delete it. Undo any time
Export
~ PNG, JPG, or PDF (A4, Letter, Legal) with page breaks placed in whitespace so text isn't sliced in half
~ Optional watermark with the page URL and capture date

Privacy
Everything happens on your computer. BlooSnap makes no network requests and collects no data. It only uses the "activeTab" and "scripting" permissions, so it only touches the tab you click it on. If you'd like to go out of your way to email me with your life story I'm all ears! :-)

PS:
don't forget to mash the worms.
