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
- Upload at 2× the display size where possible — extra pixels buffer against platform compression artefacts
- Always check your profile photo at thumbnail size (40px) — a face that looks fine at full size can become unrecognisable miniaturised
- Use PNG for graphics with text overlays — JPG compression degrades text edges at smaller sizes
- Avoid placing critical content in the outer 10% of any image — platforms may crop or overlay edges
- Back up processed images in cloud storage — losing a batch of correctly sized images means starting over
Common Mistakes to Avoid
- Not checking on mobile: Images that look correct on desktop often appear differently on mobile devices. Always preview on multiple screen sizes before publishing.
- Overwriting originals: Always save processed files with a new name or in a new folder. If you make a mistake, you need the original to start again.
- Skipping alt text: Every image on a website should have descriptive alt text. Missing alt text harms accessibility and reduces search engine visibility.
- Uploading without compressing first: Social platforms compress all uploaded images automatically. Starting with an already-compressed image compounds the quality loss.
Frequently Asked Questions
How do I get the best quality results?
Always start with the highest-resolution original image available. The tool works best when downsampling (making images smaller) rather than upsampling (making images larger). If you need to enlarge an image, use the Image Enlarger tool which uses AI to add detail rather than simply stretching pixels.
Can I use this tool on my phone?
Yes. imgresizr.com works on any modern smartphone browser including Safari on iPhone and Chrome on Android. The interface adapts to smaller screens automatically. All processing happens on the device, so you do not need a fast internet connection to process images once the page has loaded.
Is there a limit on how many images I can process?
No — imgresizr.com has no limits on the number of images you can process. You can process one image or hundreds in a single session without creating an account. The only practical limit is your device's available memory, which typically allows files up to 50 MB to be processed without issues.
