Image cropper
Drop an image, drag a rectangle, hit crop. Your image never leaves the browser.
How tight should the crop be?
Tight enough that the subject is unmistakable, loose enough that the reader can locate it on the page if needed. A few hundred pixels of surrounding UI usually buys enough context for a bug report or design note. See crop screenshot for the longer answer.
Cropping in the capture flow vs after
Cropping after the capture (this tool, plus most desktop screenshot apps) is flexible: you can keep the full screenshot and crop different regions out of it. Cropping during the capture is faster when you already know what you want. Cobalt Capture does it during, with dictation attached, so the crop and the explanation get published together as a single document.
Want cropping plus dictation plus markdown export in one tool?
Cobalt Capture lets you grab a region of your screen, talk through what's wrong, and publish it as a markdown document an AI coding agent can read. Free, no install.
