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.
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.
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.
