QR Generator API

Generate professional, styled QR codes with a single GET request. Free, no API key, open CORS — the same engine behind this site.

Quick Start

One URL is all you need. Open it in a browser, an <img> tag, or curl:

GET https://qr.diqitech.com/api/qr?data=https://diqitech.com

Basic Parameters

Parameter	Values	Default	Description
datarequired	text, max 2000 chars	—	Text or URL to encode.
format	png · svg	png	Output image format.
size	64–1024	320	Image width & height in px.
margin	0–10	2	Quiet zone around the QR, in modules.
ecc	L · M · Q · H	M	Error correction level. Auto H when a logo is set.

Styling Parameters

Parameter	Values	Default	Description
style	square · dots · rounded · classy	square	Dot / module style.
corners	square · extra-rounded	square	Corner eye (finder) style.
dark	hex, with/without #	000000	Pattern color.
light	hex (8-digit = alpha)	ffffff	Background color.
cornercolor	hex	= dark	Corner eye color.

Dot Styles

Live renders straight from the API — combine any style with the styling parameters above.

Logo Parameters (SVG only)

Parameter	Values	Default	Description
logo	https URL, max 512 KB	—	Logo image (png/jpeg/webp/gif/svg).
logoshape	circle · square	circle	Canvas & masking shape.
logosize	10–50 (%)	30 / 25	Logo width relative to the QR (default 30 circle, 25 square).
logopad	0–40 (px)	12	Padding ring around the logo.
logobg	hex	ffffff	Logo canvas color.
logoborder	hex	= dark	Canvas border color.
logoborderw	0–12 (px)	3	Border width (0 = none).

The logo is fetched server-side, scaled to cover its canvas shape, and the QR modules behind it are cleared. Error correction is raised to H automatically. Keep logosize at its default when possible — oversized logos can make the QR unscannable.

Responses & Errors

Successful requests return the image directly. Invalid input returns JSON:

{ "error": "Parameter \"size\" harus bilangan bulat 64-1024." }

400	Invalid or missing parameter — the error message states which one.
422	QR could not be generated (data too long, logo unreachable, etc).
405	Method not allowed — only GET is supported.

Good to Know

Open CORS (Access-Control-Allow-Origin: *) — call it from any website.
Responses are immutable and cached at the CDN edge: identical URLs are served from cache and count as a single generation.
Output is deterministic — the same URL always produces the exact same image.
Free to use. QR codes are generated on the fly; nothing is stored.
