Got a photo of a receipt, a screenshot of an email, or a scanned document? Zipero reads the text for you with up to 99% accuracy — no retyping needed.
Just upload your image (JPG, PNG, or JPEG) and Zipero extracts all the text, ready to copy and paste wherever you need it.
Your image is processed securely in our cloud and permanently deleted within 24 hours. We never store or use your content for any other purpose.
Optical Character Recognition transforms pixels into text through a four-step pipeline. First, preprocessing: conversion to greyscale, contrast enhancement, deskewing (correcting tilt), and noise reduction. This is the most critical step — a poor-quality or heavily tilted image halves final accuracy even with the best engine. Next, segmentation: the engine identifies text zones in the image, then breaks them down into lines, words, and individual characters.
The third step is glyph recognition. For each isolated character, the engine compares the glyph's shape against its database of character models. Modern approaches use convolutional neural networks (CNN) and LSTM (Long Short-Term Memory) networks trained on millions of text images — this is what allows Tesseract 4+ to achieve over 99% accuracy on clean printed text under good conditions.
Finally, contextual correction: the raw recognition result often contains errors (an 'l' recognised as '1', an 'O' confused with '0'). Built-in language models analyse recognised character sequences to correct linguistically improbable errors. Zipero uses Tesseract.js, the WebAssembly port of Tesseract — recognition happens entirely inside your browser on your device. No extracted text ever passes through our servers.
What languages does Zipero's OCR engine support?
Zipero's OCR engine supports over 100 languages including French, English, Spanish, German, Italian, Portuguese, Dutch, Arabic, Chinese (Simplified and Traditional), Japanese, Korean, Russian, and many more. Language detection is automatic — you do not need to specify the language manually.
What image quality is needed for accurate text extraction?
For best results, use images where text is at least 12 pixels tall, reasonably well-lit, and in focus. Scanned documents at 200 DPI or above produce near-perfect extraction results. Blurry images, very low contrast between text and background, or extreme skew reduce accuracy — straightening and brightening photos before uploading improves results noticeably.
Can Zipero OCR recognise handwritten text?
The OCR engine is optimised for printed and digital text. Neat, clearly written block-capital handwriting is often recognised with acceptable accuracy. Cursive, connected, or highly stylised handwriting will produce errors — for reliable results, stick to printed, typed, or digitally rendered text sources.
