How to Get the Best OCR Results with Umiocr: A Complete Guide

Guide OCR Tips Tutorial

Getting accurate OCR results isn’t just about the tool — it’s also about how you prepare your input. Whether you’re digitizing scanned documents, extracting text from screenshots, or processing handwritten notes, this step-by-step guide will help you get the best results from Umiocr.

Step 1: Prepare Your Image for Best Results

Before uploading, make sure your image is optimized:

  • Resolution: Higher DPI images produce better results. For scanned documents, aim for 300 DPI or higher.
  • Contrast: Dark text on a light background is ideal. Avoid grey-on-grey or low contrast documents.
  • Orientation: Make sure text is horizontally aligned. Rotated or skewed text may reduce accuracy.
  • Cropping: Crop out irrelevant borders or margins to reduce noise in the recognition process.

Step 2: Preserve the Clearest Original

Umi OCR uses one multilingual recognition model, so there is no language selector to configure. The quality of the source file matters more than choosing a language setting:

  1. Keep the original file instead of sending a screenshot through chat apps that recompress it.
  2. Prefer PNG for screenshots with small UI text and sharp character edges.
  3. Use a high-quality JPG for photos when the source includes paper texture or a camera background.

Step 3: Review and Edit the Output

Even the best OCR tool makes occasional errors. After extraction:

  • Scan through the recognized text for common OCR mistakes (e.g., confusing 1 with l, 0 with O).
  • Pay special attention to numbers, punctuation, and rare characters.
  • For technical documents, manually verify formulas, code, or specialized terminology.

Step 4: Export Your Text

Once you’re happy with the result:

  • Copy to Clipboard: Instantly copy all recognized text for pasting into a document or editor.
  • Export as TXT: Save the result as a plain text file for archiving.

Use the dedicated image to text converter for photos and screenshots, or the PDF OCR tool for scanned multi-page documents.

Tips for Specific Use Cases

  • Scanned PDFs: Make sure pages are straight and high-resolution for the best client-side processing.
  • Screenshots: Ensure your monitor scaling is set to 100% before taking screenshots for cleaner captures.
  • Handwriting: OCR accuracy on handwritten text varies; block handwriting works better than cursive.

Have fun extracting text with Umiocr!
