Heads-up
If you have the reputation, Stack Overflow's native upload is the most-frictionless option for askers. swiftimg is the bypass when you don't.
Step by step
1. Upload anonymously
Drop the screenshot at /upload — no swiftimg account or Stack Overflow rep required.
2. Paste the Markdown into your question
Stack Overflow's editor renders standard Markdown image syntax.
Markdown 3. Crop before uploading
Crop in the screenshot tool first — the cleaner the screenshot, the less editing reviewers need to do, and the better the answer you get.
Stack Overflow — FAQ
Will moderators reject an external image link?
No. Stack Overflow renders external Markdown image links the same way as native uploads. Just describe the image in the alt text so readers without images loaded still get context.
What if the screenshot has secrets?
Redact in the screenshot tool before uploading. Once it's on a public URL it's effectively published.
How long does the link stay live?
Indefinitely. Anonymous uploads don't expire; keep the delete token if you ever want to remove the image.
