Which one should you pick?
Snagit (TechSmith)
The full-featured benchmark: scrolling capture, video, templates, a capture library.
Greenshot
Lightweight and fast. Obfuscate (blur/pixelate), step counters and highlight. Interface shows its age.
ShareX
Enormously capable, including recording, OCR and upload workflows; steep learning curve.
Lightshot
Very quick capture-and-mark flow. Basic tools only; the upload button makes images public.
Skitch (Evernote)
Loved for its bold arrows; little active development.
macOS Markup
Always there after ⌘⇧4. No blur or numbered steps.
Windows Snipping Tool
Win+Shift+S, pen, highlighter; shapes arrived in recent Windows 11 versions.
AnnotateFast
Paste and mark up in a tab; nothing uploaded. No capture or video: use your OS shortcut to capture.
Choose by situation
- You file bugs all day on your own Windows machine: Greenshot for speed, ShareX if you also want recording and automation.
- You’re on a Mac and only need arrows and text: the built-in Markup is enough.
- You need blur, numbered steps or a presentation frame without installing anything (a locked-down work laptop, a Chromebook, a client’s machine): AnnotateFast in the browser.
- You need scrolling capture, video and templates in one app: that’s what Snagit is for, and it’s worth paying for.
A note on screenshot privacy
Tools that upload for easy sharing turn a private screenshot into a public URL. Lightshot’s prnt.sc links are the best-known example: short IDs that can be guessed. If a screenshot contains customer data or credentials, keep it local, redact it, and share it inside your ticket tracker.
