Text QR code generator
A text QR code holds plain words, with no link, and a phone camera shows them on screen when scanned. Opo Codes makes it for free in your browser, with no account, and reads the code back to check the text comes out the same before you print.

How to do it
- Open the generator with Text already selected.
- Type or paste the text. Line breaks are kept.
- Wait for the VERIFIED stamp and check that the preview matches what you meant.
- Download the code and print it where the words are needed.
What is inside the code
The code holds your text exactly as you typed it, with no prefix and no wrapping. Phone cameras show it as text. If the text happens to look like a web address, a phone may offer to open it as one.
Worked example: a shop notice written in two languages, শুক্রবার বন্ধ। Closed on Fridays. The text is stored as it is, Bangla included, and the scan check reads it back to confirm that it comes out the same. Use the check, not an assumption, for any language other than English.
Good uses and bad uses
Text suits things that should not need the internet: an opening-hours notice, a serial number, a short instruction, a code word. For anything longer than a few lines, a link to a page is a better choice, because a smaller code scans from further away.
A blank field gives no code. Text that is too long for one QR code gets an error that names the field, and a shorter text is the fix.
Make it readable
Error correction decides how much damage a code survives. A higher level makes a denser code. The Design tab lets you pick L, M, Q or H, with M as the default. Keep the quiet zone at 4 modules.
Questions
How much text fits?
There is a limit that depends on the characters used and the error-correction level. The generator tells you when the text is too long for one code instead of cutting it.
Does it work in Bangla?
Yes, and the scan check reads the code back so you can see the Bangla comes out unchanged. A phone camera must be able to show Bangla text, which current phones do.
Will it open a link?
Not by itself. Use the URL type if you want a link, because it adds https:// when you leave it out.
Can I edit the text later?
No, it is inside the picture. Print a new code.
