Step-by-Step Guide
- Open imgresizr.com/image-to-text in any browser — works on desktop, tablet, and mobile.
- Upload the image containing the text you want to extract — JPG, PNG, GIF, and BMP are all supported.
- The OCR engine processes your image entirely in-browser using Tesseract — your image is never sent to a server.
- The extracted text appears in the output panel — review it for accuracy, particularly for handwritten or low-contrast text.
- Use the Copy All button to copy all extracted text to your clipboard in one click.
- If accuracy is low, try enhancing the image first — increasing contrast and sharpness improves OCR results significantly.
- Paste the extracted text into any document, spreadsheet, or content editor — saving you from retyping manually.
Pro Tips
- Process images in batches where possible — consistency across a set looks more professional than one-off adjustments
- Use the correct colour profile for your output — sRGB for web, Adobe RGB for print-ready files
- Check image dimensions against the platform specification each time you upload — requirements change without notice
- Remove EXIF data from photos before sharing online — GPS coordinates and camera data in the metadata can expose privacy information
- Name your image files with target keywords — it improves discoverability in Google Images and other search engines
Common Mistakes to Avoid
- Uploading images that are too small: Stretching a small image to fit a larger dimension reduces quality. Always start with an image at least as large as the target dimensions.
- Using the wrong file format: Using JPG for logos and graphics causes visible compression artefacts around edges. Use PNG for graphics, JPG for photography.
- Ignoring aspect ratio: Forcing an image into incorrect dimensions stretches or squashes it. Always maintain the correct aspect ratio for the platform.
- Over-compressing: Reducing quality too aggressively creates blocky artefacts. Aim for 75–85% JPG quality as a safe balance between file size and visual quality.
