QR Code Generator

A static QR code stores its final content directly in the QR symbol. Olivez does not replace your URL with an Olivez short link, create a hosted landing page, require an account, add a watermark, start a subscription, or put the code behind a scan counter.

That direct encoding is why there is no Olivez expiry date or Olivez scan limit. The downloaded image does not need to return to Olivez when someone scans it. A website QR still depends on the destination website remaining available, and a Wi-Fi or contact code becomes outdated when the information encoded inside it changes.

Static codes are a good fit when the destination or data is meant to stay fixed. If you need to change a destination after printing, track scans, manage campaigns, or disable a code remotely, you need a dynamic QR service instead.

Choose the content type that matches what the scanner should do. URL mode accepts HTTP and HTTPS addresses and adds HTTPS when a valid web address is entered without a scheme. Plain-text mode stores the entered text directly.

Wi-Fi mode builds a structured payload for WPA-family networks, WEP, open networks, and hidden networks. Contact mode creates a vCard 3.0 record with a name plus optional organization, job title, phone, email, website, and address. Email, phone, SMS, and location modes use mailto, tel, sms, and geo payloads.

Structured QR actions depend on the scanning device and application. One phone may offer to join a network or save a contact while another may show a preview first or ignore a field it does not understand. Check the entered data and test the finished code on the devices you expect people to use.

Change the foreground and background colors, choose square, rounded, or dot-style modules, change the corner style, set the margin, select error correction, and add an optional border, caption, or badge frame. Caption and badge text can contain up to 32 characters.

You can place a PNG or JPEG logo up to 1 MB in the center. When a logo is added, Olivez automatically switches the QR code to error-correction level H and hides modules behind the logo image. The three large finder patterns remain outside the centered logo area.

Customization should make the code easier to recognize without making it harder to scan. Olivez does not offer gradients, transparent colors, free-positioned logos, SVG logo uploads, or automatic brand extraction. Those limits are intentional parts of the current generator, not features hidden behind an account.

Start with a dark QR pattern on a light background and preserve clear space around the entire symbol. DENSO WAVE specifies a four-module quiet zone on every side of a QR code. Olivez warns when the selected margin is below four modules.

The built-in contrast warning uses a 4.5:1 relative-luminance ratio as a conservative screening check. That number is not an official QR Code pass threshold and it cannot certify a design. Module shape, data density, logo coverage, physical size, camera quality, glare, blur, distortion, print surface, and viewing distance all affect real scans.

Treat the live preview as a design preview, not a final scan test. Download the actual PNG or SVG, place it at the size and on the background you intend to use, then scan it with more than one phone before publishing, printing, packaging, signage, or a large production run.

QR Code provides four error-correction levels: L, M, Q, and H. DENSO WAVE describes approximate restoration rates of 7%, 15%, 25%, and 30% of total codewords. Higher correction adds redundancy, which can make the symbol denser for the same payload.

Olivez uses M as the default for an unmodified code and automatically selects H when you add a center logo. Q or H can also be useful when extra damage tolerance is more important than keeping the symbol as simple as possible.

The percentages do not mean that you can safely cover the same percentage of the visible QR image with a logo or decoration. Error correction operates on codewords, and scan success also depends on where damage or obstruction occurs. Keep logos modest and test the final exported code.

PNG downloads are available at 512, 1,024, and 2,048 pixels. PNG is convenient for documents, presentations, social graphics, websites, office software, and systems that expect a raster image.

SVG is the better choice when a designer needs to resize the QR code for a business card, label, menu, poster, package, or sign without raster pixelation. The current SVG export includes the selected colors, module and corner styling, logo, and optional frame.

Olivez does not add a watermark to either format. The current generator does not export PDF, EPS, JPEG, WebP, transparent-background files, or prebuilt print sheets, so check the required format before building a print workflow around the code.

QR Code versions run from Version 1 at 21 by 21 modules to Version 40 at 177 by 177 modules, with four modules added per side at each higher version. The amount and type of data plus the selected error-correction level determine how much capacity is required.

Long URLs, large vCards, long messages, and multilingual text can produce denser symbols. If a payload becomes too large to encode, shorten the content or reduce error correction when it is safe to do so. Shorter payloads are also easier to reproduce cleanly at small physical sizes.

There is no single minimum print size that is correct for every QR code. DENSO WAVE determines the required area from the symbol's module count, the physical size of each module, and the four-module quiet zone. Print a sample at the intended size and test it from the real scanning distance instead of relying on one universal centimeter or inch rule.

For print, preserve the quiet zone and avoid stretching the QR code out of proportion. Do not place finder patterns across folds, seams, die cuts, reflective areas, or edges where part of the symbol can be hidden or distorted.

A short website QR on a clean card can work at a smaller size than a dense contact code viewed from farther away. Printing resolution, ink spread, surface texture, lighting, camera distance, and the final material all matter. SVG avoids raster scaling problems, but vector output does not make an otherwise poor design automatically scannable.

Test the actual production artwork, not only the browser preview. If a code will be printed in quantity, test a physical proof with the same size, material, colors, and expected viewing distance before ordering the full run.

QR payloads, logo files, styling, previews, and PNG or SVG exports are prepared in the current browser. The entered QR content is not sent to an Olivez QR redirect, analytics system, or QR-storage service for generation.

Local generation does not make the QR image secret. Anyone who can see or photograph a QR code may be able to decode the information inside it. Be especially careful with Wi-Fi credentials, private contact details, access tokens, recovery codes, or other sensitive text.

For public codes, make the expected action clear near the symbol and use a recognizable destination when possible. People should still review a detected website or action before opening a link, joining a network, sending a message, or sharing information.
