Extract Text from Image (OCR)

That text you just can't copy — a list in a legacy app, an error in a dialog, a table in a scanned PDF or a WhatsApp screenshot? Take a screenshot, paste it here with Ctrl+V and get the text ready to edit and copy. Optical character recognition (OCR) runs entirely in your browser, and if you upload two screenshots, one click sends both texts straight to the Compare Lists tool.

Language of the text in the image:

Upload two screenshots and compare the text extracted from each with one click.

Recognition happens in your browser — images never leave your device. On first use, a language pack is downloaded.

How to verify the result

A useful tool should let you verify its output. Start with a small test, keep the original and only then use the result in production. The scenario below helps catch problems before you copy, download or share anything.

Practical check

Use a straight, well-lit image with readable type; compare accents, numbers and line breaks with the original.

What this tool does not replace

Models and filters can lose hair strands, transparency, text or fine detail. Output varies with resolution, lighting, compression and contrast; inspect at full size before publishing.

Data handling

The browser may download processing model files, but the selected image is handled locally. Performance and memory use vary by device.

What is OCR?

OCR (Optical Character Recognition) is the technology that "reads" the text present in an image and converts it into real text — selectable, editable and copyable. It's the same principle used by document scanners and camera translation apps.

Paste the screenshot and you're done

The fastest flow is the classic screenshot + Ctrl+V: capture the screen (PrtScn on Windows, Cmd+Shift+4 on Mac), come to this page and paste. The image joins the queue, progress shows in real time and the extracted text appears in an editable field — because OCR isn't perfect, and sometimes you'll want to fix a letter or two before copying.

Built for comparing lists from screenshots

This tool was born from a real problem: comparing two lists that couldn't be copied, only screenshotted. So when you extract text from two images, a "Compare both lists" button appears — it sends both texts straight to our Compare Lists tool, which shows what exists only in the first, only in the second and in both.

Your images never leave your device

All recognition happens locally, in your browser — screenshots are never uploaded to servers. On first use, a language pack for the chosen language is downloaded (a few megabytes); after that, the process gets faster.

Tips for best results

OCR works best with sharp, reasonably sized text: prefer captures at 100% zoom, avoid blurry photos and crop to the area of interest before pasting. Very small text, decorative fonts and heavily compressed images increase reading errors — which is why the result is always editable.

How to use

Pick the language of the text in the image (Portuguese, English or Spanish). Paste the screenshot with Ctrl+V, drag the file in or click to select — multiple images are fine. Wait for the reading, review the extracted text in the editable field and hit "Copy". With two processed images, click "Compare both lists" to see the differences in the Compare Lists tool.

Frequently asked questions

Are my images uploaded to any server?

No. Recognition runs entirely in your browser — images never leave your device. Only the language pack is downloaded, once.

Does OCR always get it right?

No OCR is perfect. With sharp screen captures (menus, lists, error messages) accuracy is very high; blurry photos, tiny text or decorative fonts reduce quality. The result field is editable precisely for fine-tuning.

Which languages are supported?

Portuguese, English and Spanish — you choose before uploading, and the right language noticeably improves accuracy (accents, ç, ñ).

Does it work with photos of paper documents?

Yes, as long as the photo is sharp, well lit and not heavily tilted. For important documents, review the extracted text carefully.

How do I compare the text of two screenshots?

Upload both images; once both are processed, the "Compare both lists" button appears and sends both texts straight to the Compare Lists tool.
