QR codes as a product feature

After signing in, customize QR colors, frames, captions, logo text and element placement, add a background or contact card, and export SVG, PNG or PDF. In link mode, changing the destination does not require reprinting the QR code. In vCard mode, contacts are embedded in the code: a printed code cannot be updated and its scans are not recorded by the service.

QR codes, contact cards and printing

Dynamic link and embedded vCard

In link mode, the QR contains the click address on the link /qr/{code}. The crawl accesses the service, so the target URL can be changed without retyping as long as the domain and ID are preserved. Terms, limits, access restrictions and link routing apply. Crawls are counted separately from regular link clicks.

In vCard mode, the QR contains contact information directly inside the image. The phone prompts you to save the contact. Already printed contact information cannot be updated by changing the record in the service: you need to create and distribute a new QR. Reading the built-in vCard does not access the /qr/{code}, so you cannot expect statistics on its scans on the site.

Visual business card and QR content are separate settings. Contacts printed next to a QR do not automatically become the content of the code. Always check the selected content mode.

Working with the editor

• Open the link card → QR.

• Choose your original layout: square, poster, or business card.

• Adjust the canvas width and height, QR size and position.

• Specify the QR, background, and accent colors. The color of the QR itself and the background should be different; Maintain strong contrast for easy scanning.

• Select a frame: solid, dotted or no frame; adjust the indentation, thickness and rounding.

• Add frame text, signature and text logo. If necessary, adjust their size and position.

• Drag and drop objects in the preview; use resizing handles. Exact coordinates are also specified in the form fields.

• Add decorative blocks, select the one you want from the list and change its position, size, rotation, fill, stroke and transparency. Delete the unnecessary block.

• Turn on Preview mode to see the layout without editing elements. Clicking on the layout returns editing.

• Save the design, then download the desired format and check the finished file.

Available block shapes: rectangle, circle, ellipse, triangle, diamond, rounded block, hexagon, star and line. Up to 40 blocks are supported. Objects can overlap each other: to drag, select a free part of the desired object or use its coordinate fields. Do not cover the service squares and the white field around the QR with decorative elements.

Canvas sizes are limited to 240–2000 pixels on each side; values ​​that are too large or small are normalized by the service. The QR must fit on the canvas. Frame text is limited to 80 characters, signature - 160, logo text - 32. For long text, check the downloaded file, especially before printing.

Background and contact information

For background images, PNG, JPEG and WebP are supported, up to 3,000,000 bytes. Image size - no more than 4096x4096, no more than 16 million pixels. Choose fill with clipping, fit entirely, or stretch, then adjust the opacity from 0 to 100%. To remove, use the separate background removal checkbox and save the form.

In business card mode, name, organization, position, phone, email, website and address are available, as well as design layouts, alignment and text options. For vCard, fill in at least one of the fields: name, organization, phone or email. The email must be correct, the website must be an HTTP/HTTPS address.

Download and print

• SVG is suitable for scaling and vector layout.

• PNG is convenient for inserting into documents and publishing in raster form.

• PDF is convenient for transferring layout and printing.

• The print page offers business card, flyer, menu, and packaging layouts; use the print button and check the options in the browser dialog.

Scan exactly the exported file or proof print on a real device. Check the target URL, sharpness, margins and readability at the intended size. The monitor preview does not guarantee the quality of a particular printer or camera.

If only the target URL of a dynamic link is updated, the old QR is retained. If the domain, ID, content mode, or embedded vCard changes, prepare and distribute a new QR. Expiration or deletion of a link affects old dynamic QRs in the same way as a regular short URL.

Cancel changes and check readability

The «Undo change» and «Redo change» buttons work with the history of the current editor: up to 59 steps are available. Loading a new background file starts the history over; after reloading, the saved layout is used. During vCard data changes, the preview rebuilds the code. If the data does not pass verification or the request fails, correct the fields; do not use an unfinished preview for publishing.

First, save the layout, then open «Checking QR readability». The service tries to read the finished PNG and compares its data with the expected one. The report shows the image size, module size, and contrast. Warnings help identify pale colors, overly small codes, inverted colors, and overlaps with logos, text, or shapes. Values of 4 pixels per module and a contrast of 4.5:1 are practical guidelines for this check, not a guarantee that all cameras will read it.

Download the JSON report if necessary. Changes not yet saved in the editor are not included in the report or export. The check does not create clicks on links. Before running a print run, scan the final file with different devices and perform a test print at the actual size. If the limit for layout size, background file, or number of shapes is reached, reduce the corresponding value. Limits account for the availability of the feature for both the owner and collaborators.

How to apply this section

Each topic explains a feature, the user decision behind it, and how to use it without making the link harder to manage. Read the checklist before changing a link that is already shared.

Before you publish or update

  • Start from the visitor experience: who opens the link, from where, on which device, and what should happen next.
  • Check that the destination is correct, opens quickly, and shows the expected page for the intended audience.
  • Choose only the controls that match the goal, such as expiration, password, referrer, QR design, UTM, routing, or analytics sharing.
  • Save a short note for important changes so future review, rollback, or teamwork stays clear.
  • Open the short link in a private browser session and, when relevant, test mobile, desktop, QR scan, and protected access paths.
  • Review analytics after sharing to confirm real visitors, source quality, device mix, and campaign performance.

Practical example

Example: create a test link for an internal page, add a clear slug, set a short expiration, enable preview if the destination is sensitive, scan the QR code from a phone, then check whether the visit appears in the link statistics.

Next step

After this topic is clear, combine it with one adjacent feature. For example, pair UTM with campaigns, QR with print layouts, targeting with fallback, or webhooks with conversion tracking.
