How to Extract Text from an Image Online — Free OCR, No Upload (2026)
Getting text out of an image — a screenshot, a scanned document, a photo of a sign — normally means uploading to a service that logs your file, charges after a daily cap, or handles only one image at a time. This guide covers how to do bulk OCR in your browser using the Tesseract engine, with no upload required and support for 19 languages.

When you need image OCR
Screenshots of text
Error messages, code snippets, WhatsApp exports, ticket screenshots — any text displayed on screen that cannot be copy-pasted.
Scanned documents
Old reports, printed invoices, physical contracts, or any paper document that was scanned to an image rather than a searchable PDF.
Product labels and signs
Photographed ingredient lists, warning labels, foreign-language signs, or menu items. Select the correct language and extract the text.
Batch digitization
Process a folder of scanned pages at once. Drop up to 50 images and download all results as a ZIP — no clicking through one by one.
Step-by-step guide
Open the Image to Text tool
Go to simpletool.co/image-to-text. On first use, the Tesseract language pack downloads (5–15 MB) and caches locally. English is the default; switch to another language before processing if needed.
Drop up to 50 images
Drag and drop JPG, PNG, WebP, BMP, GIF, or TIFF files — up to 50 at once. Images are queued and processed sequentially in the browser. Results appear as each image finishes.
Select the language
Choose the language of text in your images. If you have a mixed-language batch, process each language group separately. The engine performs best when the selected language matches the text in the image.
Wait for OCR
Processing takes 2–30 seconds per image depending on image size and complexity. A progress indicator shows each image as it completes. The browser tab stays responsive throughout.
Copy or download results
Copy text from individual image results with one click, or download all results as a ZIP archive of .txt files. Each file is named to match the source image filename.

Open Image to Text Tool →Tips to get the best OCR accuracy
- →Use high-resolution images: 200+ DPI gives Tesseract enough detail to distinguish similar characters. Low-DPI images — especially JPEG screenshots saved at low quality — produce significantly more errors.
- →Ensure the image is upright: Tesseract expects horizontally-aligned text. Rotated or skewed images produce poor results. Most image editors have a straighten or deskew function — apply it before OCR.
- →Select the correct language: The language setting controls which character set and word dictionary the engine uses. Mismatched language and text content is a common source of errors on otherwise clean images.
- →Avoid overly compressed JPEGs: JPEG compression artifacts blur character edges. If you are scanning documents, save as PNG or TIFF instead of JPEG for input to OCR.
Frequently asked questions
How accurate is browser-based OCR?
On clean, high-contrast images at 200+ DPI — printed documents, clear screenshots, scanned books — character accuracy is 95%+. Accuracy drops on handwriting, low-DPI or blurry images, unusual fonts, colored backgrounds with low contrast, and photos taken at an angle. The engine handles typed text best; handwriting accuracy is limited and should be treated as a rough draft requiring human review.
What languages are supported?
Nineteen languages: English, Spanish, French, German, Russian, Portuguese, Italian, Dutch, Polish, Turkish, Arabic, Hindi, Japanese, Korean, Chinese Simplified, Chinese Traditional, Thai, Vietnamese, and Ukrainian. Each language uses a separate model pack (5–15 MB) that downloads on first use and caches locally — subsequent uses load instantly without re-downloading.
Can I extract text from screenshots?
Yes, and this is one of the strongest use cases. Screenshots of error messages, code, receipts, product listings, or any text-heavy UI tend to be high-contrast and consistent fonts — exactly what Tesseract handles best. Paste or drag a screenshot directly and the text is extracted in seconds. One limitation: multi-column layouts (like two-column articles or side-by-side UI panels) may merge columns into a single text stream.
Can I process multiple images at once?
Yes — up to 50 images per batch. Drop all files at once and each is queued and processed individually. Results appear as each image completes. You can copy text from individual results or download all extracted text as a ZIP archive of .txt files — one file per image.
Does it work on scanned documents?
Yes. Scanned PDFs should be converted to images (JPG or PNG) first — most PDF viewers have a Save As Image option. The scan quality matters significantly: a 300 DPI scan from a flatbed scanner transcribes very accurately; a smartphone photo of a document held at an angle transcribes poorly. Flatten and deskew scans before processing if accuracy is critical.
Why does it struggle with code in screenshots?
Tesseract is trained primarily on natural language text. Programming syntax characters — brackets, underscores, semicolons, angle brackets — look similar to other characters in many fonts and get misread. For code screenshots, the extracted text is useful as a starting point but will likely need manual correction. Alternatively, use the interactive clickable transcript if you can access the source.
How is this different from Google Lens or built-in phone OCR?
Google Lens sends your image to Google servers for processing. Phone camera apps (iOS Live Text, Google Lens) are convenient for one-off needs but have no batch capability. This tool processes up to 50 images at once entirely in your browser — useful when you have a stack of scanned pages, a folder of screenshots, or any situation where server uploads are inconvenient or a privacy concern.
Does the image get uploaded to a server?
No. The Tesseract OCR engine runs as a WebAssembly module in your browser tab. Your images stay in device RAM and are released when you close the tab. Many free OCR services explicitly reserve the right to retain or scan uploaded images — this tool has no such policy because nothing is uploaded.
