Short Answer: Yes — With Normal Caution
Capture2Text is free, open-source (GPLv3) software by Christopher Brochtrup, distributed as a plain zip archive with no installer. It holds a 4.7/5 rating from 89 votes on SourceForge. There is no bundled adware (there is no installer to bundle it into), and the source code is public for anyone to inspect. That is a strong safety profile for a desktop utility.
Why It Scores Well on Safety
- Open source (GPLv3). The code is public on SourceForge — no black box. Anyone can verify what it does.
- No installer, no bundling. You get a zip of program files. The classic “decline the toolbar offer” problem cannot exist.
- OCR is fully offline. The Tesseract engine runs locally. The only feature that touches the network is the optional Google Translate integration, which you must explicitly enable in Settings → Translate — and which honestly requires internet by design.
- Long track record. Years of public releases on SourceForge with a solid user rating.
The Honest Caveat: No Updates Since 2022
v4.6.3 (2022-03-19) is the latest release. Maintenance stalling is worth knowing about, but keep it in perspective:
- An offline OCR tool has a tiny attack surface — there is no server, no auto-updater phoning home, no account system to breach.
- What you actually miss is new features and compatibility polish, not security patches for a network service.
- It still runs on Windows 10 and (per widespread user reports) Windows 11.
If you need actively developed software with support, that is a legitimate reason to look at alternatives — not a safety reason to fear this one.
Staying Safe: Practical Tips
- Download from the official source — the SourceForge project page (linked from our download page), not random re-upload sites.
- Scan the zip with Windows Defender or your antivirus before extracting. A clean scan of the official zip is the expected result.
- Expect a possible heuristic flag. Small unsigned utilities that register global hotkeys sometimes trip generic AV heuristics. A vague “suspicious” verdict on the official zip is usually a false positive — check the detection name rather than panicking.
- Keep translation off if screen privacy matters to you — remember it sends text to Google Translate.

Frequently Asked Questions
Is Capture2Text safe to download and use?
Yes, with normal caution. It is GPLv3 open-source software with publicly available source code, distributed as a plain zip with no installer and no bundled software, and it holds a 4.7/5 rating from 89 votes on SourceForge. Download it from the official SourceForge page (or our download page) and scan the zip with your antivirus if you want extra assurance.
Is Capture2Text still maintained? The last release was 2022.
Correct — v4.6.3 (2022-03-19) is the latest release and there has been no newer version since. The software still works on Windows 10/11. Stalled maintenance is not the same as unsafe: Capture2Text’s OCR runs fully offline, so there is no server component to be compromised; the main thing you miss out on is new features.
Does Capture2Text contain malware or adware?
No. There is no installer at all — just a zip of program files — so there is nothing to bundle adware into. The source code is public on SourceForge under GPLv3, which means anyone can inspect exactly what it does.
Does Capture2Text send my screen content to the internet?
The OCR itself is 100% offline (Tesseract runs locally). The only network feature is optional translation via Google Translate, which by definition sends the captured text to Google — and it requires you to enable it in Settings → Translate. If you never enable translation, nothing leaves your PC.
Why does my antivirus flag Capture2Text?
Some antivirus products heuristically flag small, unsigned, niche utilities — especially ones that register global hotkeys (which Capture2Text does by design). If your AV quarantines it, check the detection name: a generic “suspicious”/heuristic flag on the official zip is typically a false positive. You can also build from the public source yourself for full certainty.
Is Capture2Text really free and open source?
Yes. It is free of charge and licensed under the GNU General Public License v3 (GPLv3), by author Christopher Brochtrup. Free here means both gratis and libre — you can use, study, and modify it.
