Quick answer
Keep complete characters, readable text size, even lighting, and straight text lines. Choose the main language in the image. Compare names, totals, dates, codes, and punctuation with the original before copying them into another document. A confidence percentage does not verify each character.
The Image to Text OCR Tool accepts one still PNG, JPEG, or WebP at a time. It has no crop, rotate, contrast, or sharpening controls. Prepare a copy in your image editor, or retake the photograph, before selecting it here.
Fix the source image before applying filters
If a bright reflection covers a price or account code, move the camera, document, or light and take another image. Sharpening cannot recover characters that the photo never captured. Keep the original so you can compare it with any edited copy.
For tiny text, use a larger original or a closer, focused photo. Enlarging an existing image may help recognition, but it cannot restore missing detail. Change one condition at a time, then compare the same line of output. That makes it easier to see whether the edit helped.
Tesseract.js's worker APIrecommends sufficiently high-resolution input and notes that upscaling can improve results.
Keep a border, and straighten the lines
Crop unnecessary surroundings without cutting through letters. Leave a small margin around the text. Rotate a tilted image until its lines are horizontal. Check the first and last character after saving: a neat crop can still remove part of a reference number.
Tesseract's quality guide covers uneven backgrounds, noise, rotation, borders, and resolution. Its 300 dpi recommendation is scan guidance, not a pass threshold for this browser tool. The tool checks image dimensions and byte size; it does not judge whether your text is readable. A heavy filter can erase punctuation, so compare edited and original images closely.

Choose the language, then check the words
This tool offers English, Spanish, French, German, Italian, and Portuguese. Select the main language yourself; it does not automatically detect it. For a Spanish document, choose Spanish and check accented words, names, and any foreign-language text in the result. A matching language file is not a guarantee that every accent or proper noun will be right.
Keep a short checklist of fields that matter. On a receipt, compare the currency sign, decimal separator, total, date, and reference number. On a form, compare names and identifiers. Keep leading zeros in codes. If the output and image disagree, correct the text from the image; do not use a high confidence percentage to settle the disagreement.
Try one checked English example
Download the synthetic English sample. It is a 1,200 by 220 pixel PNG with black 64px Arial text on a white background. Its reference line is ACCESS FREE TOOLS 12345. This simple image helps you check the image selection, recognition, and copy controls without using a private document.
- Open the OCR tool and select the downloaded PNG.
- Choose English, then press Read text.
- Compare the result with
ACCESS FREE TOOLS 12345. - Press Copy result and paste it into a text editor to check the copied line.
An automated Chromium check on October 5, 2026 used the real tool component and its local Tesseract.js 7.0.0 assets. It recognized that exact line and copied the same line to the browser clipboard. The check blocked external requests. It establishes this one simple English workflow, not a measured accuracy result for blur, glare, receipts, Spanish, or other devices.
For your own document, keep the source image and compare the text before and after an edit. Record the selected language and any changes to the image. A few successful lines are useful checks; they do not establish a general OCR accuracy rate.
What the browser downloads and processes
The current OCR component prepares the selected image and sends it to a worker inside the browser for recognition. Access Free Tools serves the worker, WebAssembly core, and selected language files from its own model directory after you press Read text. The recognition path does not upload the image to the site server.
Tesseract.js supports explicit worker, core, and language-file paths. This tool uses those local paths rather than the default external downloads. The page still makes support-file requests, and the site has separate analytics and session replay. A tool-usage event is not the image or extracted text, but local recognition alone does not establish anonymity for the whole page. Read the Privacy Policy before handling sensitive documents.

When the result needs another check
The current input limit is 10 MiB, with at most eight million pixels and neither side above 8,192 pixels. Resize a copy if needed. This is a one-image text extractor, not a multipage PDF reader, layout-preserving converter, or verified handwriting service.
A different font, camera, language, browser, or Tesseract version can change recognition. Verify important financial, medical, legal, or identity text directly against its source. The full OCR guide explains the supported inputs and controls. Use the OCR tool to save typing, then check the draft before it becomes a record you rely on.
