How to copy text from terminal screenshots on Mac
Terminal screenshots are common in bug reports, chats, and incident threads. They are also painful when you need the exact command, path, or stack trace. GlassCopy lets you recover terminal text without retyping long lines by hand.
Why copy fails here
Once terminal output is shared as an image, the commands and logs become unselectable pixels even though they still look like live shell text.

Try the cleanest source first
Native copy check
Use raw logs or terminal scrollback when you have access. Use GlassCopy when the terminal content is only available as a screenshot, shared image, or remote screen.
Why GlassCopy helps
GlassCopy turns a terminal screenshot into reviewable text on your clipboard, but it keeps you in control: always inspect OCR output before running or sharing commands.
How to do it with GlassCopy
Terminal content often includes monospace text, prompts, stack traces, and file paths, so the best workflow is to capture one command block or error section at a time.
Terminal screenshots often contain small glyphs and dense lines. Enlarging the image before OCR helps preserve punctuation and case.
Use GlassCopy on a tight region such as one command, one traceback segment, or one log cluster rather than the whole screenshot.
A monospaced editor makes it easier to verify spacing, punctuation, flags, and file paths before you reuse the text.
Commands, hashes, and flags are sensitive to even one wrong character, so review the output before executing it.
What to capture, what to leave out
Select
The command, first meaningful error lines, file path, or stack frame needed for debugging.
Leave Out
Prompt decorations, shell history, access tokens, internal hosts, and unrelated output above or below the failure.
Best Conditions
Zoom monospace text until punctuation is clear and capture one command/output block at a time.
Tips that improve results
Helpful habits
- Split wide stack traces into smaller OCR passes so symbols and file paths stay readable.
- Capture prompts and commands separately if the prompt styling is visually noisy.
- Look closely at characters like 0, O, 1, l, and punctuation in flags or paths.
Avoid these mistakes
- Do not execute OCR output blindly if it came from a screenshot of a shell command.
- Avoid including terminal tabs, sidebars, or surrounding chat UI in the selection.
When not to use this workflow
If the raw log or command is available in the ticket, repo, or terminal history, use that source instead of OCR output.
Clean up and verify
After OCR
- Review every flag, quote, slash, dash, and path before using the text.
- Wrap copied output in code formatting when sending it to teammates or an assistant.
- Remove secrets, tokens, customer IDs, and internal URLs before sharing.
Accuracy watchlist
- OCR can confuse hyphens, underscores, slashes, pipes, and quotes.
- Long stack traces lose value when captured without the top exception or failing command.
- Colorized terminal output can reduce contrast for warnings and paths.
Privacy boundary
Terminal output can expose secrets. Redact tokens, keys, internal hosts, and customer identifiers before pasting copied text anywhere.

Questions people ask
Can I copy commands or stack traces from terminal screenshots?
Yes, but review the copied text carefully. OCR can change symbols that matter in commands and paths.
Should I run an OCR-derived terminal command directly?
No. Paste into a scratch area first and verify every flag, quote, slash, dash, and path before running anything.
What terminal text should I capture?
Capture the command, the first meaningful error lines, and the relevant file path or stack frame, not the entire shell history.
