Read the QR codes in an image and get the decoded text.

Questions people ask

How many QR codes can one image hold?: As many as fit. The tool reports up to 100 codes in reading order, top left to bottom right, and says so when the cap binds. Each code is reported on its own, with the full values written verbatim to the downloadable text file.
My photo is sideways. Does that matter?: Usually not. EXIF orientation is applied first, the scanner itself tries turned and inverted readings, and the image is retried at the 90, 180 and 270 degree positions if the upright scan finds nothing. The report says which orientation produced the result.
What about barcodes that are not QR codes?: They are found and counted, and their type is named in the report, but they are not decoded: this tool reads QR Codes only. If the image holds a Code 128 strip and nothing else, the tool refuses with that fact stated rather than returning something the page cannot carry.
Why is no QR code found in my image?: The usual reasons are a code that is too small in the frame, blur, low contrast or a missing quiet zone (the empty border around the code). The refusal says this rather than inventing a cause. Try a sharper crop or a larger capture, and keep some white space around the code.
Is a QR code's content safe to open?: Not necessarily. Decoded content is untrusted text. The tool never opens, visits or executes it, and neither should you blindly: a QR code is just text carrying, and attackers use them to hide phishing links. Read the value first.
What happens to my image and the decoded text?: The upload is deleted as soon as processing finishes; the decoded values and the report stay downloadable for about 10 minutes, then are deleted automatically.

About this tool

A QR reader with its boundaries stated plainly. Only regular QR Codes are decoded; other barcode symbologies are counted and named, never returned, so the page never carries data the tool did not promise. Results come in reading order with a counted cap, and the full values are written verbatim to a text file. Decoded content is untrusted text that is never opened, visited or executed by the tool. Technical details: the image is opened with Pillow, EXIF rotation claims are applied, and the scan runs with the zxing barcode library, which tries turned, inverted and downscaled readings by itself. When the upright scan finds no QR Code, the image is retried at the 90, 180 and 270 degree positions and the first successful orientation is recorded. Found codes are ordered by scanner position, top left to bottom right. Honest limits: the tool does not recover codes from deliberate damage (torn, scribbled or mostly missing codes), does not read Micro QR or other symbologies, and does not judge whether decoded content is safe or real. A blurry photo of a distant code is a refusal with the reason named, never a guess.
