Notes on turning a post into a picture — the device shortcuts, the export sizes that survive a platform’s re-compression, and the decisions behind the tool itself.
Three kinds of thing get written about here. The first is mechanical: which key does what on which device, and which number belongs in which field. The second is what happens to an image after you upload it — platforms crop and re-encode, and most of the reason a tweet card looks bad in a feed was decided before you pressed post. The third is the tool itself: what it does, what it deliberately refuses to do, and why.
Everything here is written against the editor on the home page, so the numbers are the real numbers — a 598px card, a 2× export at 1196px, 3:4 and 9:16 crops that centre the card vertically. If you want the setting-by-setting reference rather than the essays, the guide has it.

How to Screenshot a Tweet on Any Device
The gesture takes two seconds; making the result publishable is the part nobody writes about. Here is the exact shortcut on every device, the browser trick that captures a single tweet at any resolution you like, and the six things that make a raw screenshot look wrong in a slide or a feed.

Tweet Screenshots for Instagram: Sizes, Crops and a Workflow That Scales
Instagram displays at 1080px wide, crops the feed to 4:5, and re-encodes everything you upload as JPEG. That is three constraints a phone screenshot of a tweet fails all at once. Here are the numbers that work, why a 2× export is exactly the right size, and how to keep a twelve-slide carousel looking like one set.

Why I Built Tweet to Image — and the Detail That Almost Killed It
I needed one tweet in one slide and spent forty minutes not getting it. What followed was four wrong numbers, a font I could never match, and a week where the honest answer looked like “there is no product here”. The fix turned out to be changing the claim rather than the code.

The tool is on the home page and needs no account — paste the text, fill in the numbers, export a PNG. The guide covers every setting one by one, and the about page explains how the card is rendered and where the resemblance to X stops.
