よくある質問

How do I extract text from an image?

Drop a PNG, JPG, or WebP into the box above (or choose a file). The tool reads the words in the image right in your browser and lists them as text you can copy or download as a .txt. Nothing is uploaded to a server.

Is my image uploaded anywhere?

No. Unlike most image-to-text tools, the recognition runs entirely in your browser using on-device OCR. Your image never leaves your computer or phone — it is not sent to Captioner or anyone else.

What image formats can I use?

PNG, JPG, and WebP. Screenshots and photos both work; the clearer and higher-contrast the text, the better the result.

Can it extract text from a screenshot or a photo?

Yes — screenshots, photos of signs or documents, slides, and social posts all work. High-contrast, roughly horizontal text reads best; very stylized, rotated, or handwritten text may come out imperfect.

Can it pull captions or subtitles out of an image?

It reads burned-in captions along with everything else visible in the image. Note that it extracts all visible text, so handles, timestamps, and watermarks can show up too — caption-only filtering is on the way. To create or edit real subtitle files for a video, use the Captioner editor.

What languages does it support?

It recognizes English and many other Latin-script languages, plus Chinese and several more. Accuracy is strongest for clear printed English; other scripts and low-quality images vary. (Japanese is not supported in this version.)

Is it really free?

Yes. No signup, no watermark, no upload — extract text from as many images as you like, free.
