About QR Reader

QR Reader decodes the QR code in an image and hands back the embedded data plus where the code was found in the picture. Use it when someone sends you a screenshot of a QR code and you need the underlying URL or text without pointing a phone at the screen. Decoding runs in your browser, so the image you drop in is never uploaded.

Common uses

  • Pull the link out of a QR code screenshot a colleague pasted into chat, without reaching for your phone
  • Read the Wi-Fi credentials encoded in a QR image saved from a router setup page
  • Recover the URL behind a QR code on a flyer photo before clicking through on a trusted machine
  • Extract a one-time-password setup secret (otpauth URI) from a 2FA QR screenshot
  • Verify what a QR code you generated actually encodes by decoding the exported PNG
  • Get the bounding-box location of a code in a busy image to confirm it scanned the right one

Frequently asked questions

Which image formats can I decode?

It reads QR codes from PNG, JPEG, and WebP images. Drop in a screenshot or photo containing the code.

What does it return?

It returns the decoded data (such as a URL or text) and the code's location within the image, as JSON.

Does my image get uploaded?

No. The decode happens locally in your browser, so the image and whatever the QR code contains stay on your device.

Will it open or follow the link inside the code?

No. It only extracts and shows you the data. You decide whether to act on a URL, which is safer than auto-scanning an unknown code with your phone.

What if the code is blurry or partly cropped?

QR codes include error correction, so mild blur or a small obstruction often still decodes. A heavily cropped or very low-resolution image may fail; a sharper capture helps.

Extract PDF Tables
export

Extract tabular data from a PDF as JSON or CSV. Works well for simple tables with aligned columns and no merged cells. Complex tables, rotated text, and scanned PDFs (images) will not extract cleanly.
