Make a WiFi code that scales to any sign
An SVG WiFi code stores the network pattern as vector shapes, so one file prints crisply on a small table tent and a large wall sign alike — no blur, no re-exporting for each size. Scanning it still hands the phone your SSID and password; the vector format only changes how sharp it stays in print.
For a WiFi code this pays off because it usually becomes long-lived signage shown at more than one size — a counter card, a decal, a poster. One SVG covers all of them and opens in Illustrator for a brand colour. The one thing vector won't fix is a wrong encryption setting.
Vector output for signage at any size
A PNG is locked to its pixel grid, so a WiFi card exported small turns fuzzy when enlarged for a wall. SVG stores the modules as shapes with no fixed resolution, so the same file is sharp from a 3 cm table tent to a metre-wide poster, and a print shop can output it at full device resolution.
Because a WiFi code is displayed rather than handed over, that scalability is genuinely useful — you design the sign once and reuse the code everywhere.
- One vector for table tents, decals and posters.
- Sharp edges at any print size, no blur.
- Small file for a simple black-white pattern.
- Editable in Illustrator, Inkscape, Figma.
Recolouring to match the venue
Open the SVG in a vector editor and the modules are shapes you can tint to a café or brand colour, set on a transparent background, or drop into a menu layout. This is why venues prefer vector for WiFi signage that has to look designed, not bolted on.
Keep the code darker than its background after recolouring. A light code on a dark sign loses the contrast the camera needs, and a WiFi scan that fails leaves guests stuck asking for the password anyway.
Get the encryption right before exporting
Vector quality is irrelevant if the network details are wrong, so set the encryption field to WPA for a standard router before you generate. A mismatch makes a code that scans perfectly but refuses to connect — and once it is on printed signage, that is a costly fix.
If the password contains a semicolon, colon or backslash, those are structural in the WiFi format and must be escaped; a plain alphanumeric password is safest for unattended signage guests scan on their own.
Export a WiFi code as SVG
- Enter SSID and password exactly. Match the network name's capitalisation precisely; a mismatch produces a code that scans but never joins.
- Set encryption to WPA. Confirm the encryption field before export — a wrong value is the top reason a WiFi sign fails to connect.
- Choose SVG on download. Select vector so the sign stays sharp whether it is a small table tent or a large poster.
- Recolour with contrast in mind. If you tint it in Illustrator, keep the code darker than the background so guests' cameras still lock on.
Technical details
- Maximum characters: 4296
- Recommended error correction: M (medium) — the default suits a clean vector sign; raise it to Q if the printed WiFi code will be handled or scuffed over long counter use.
- SVG stores the WiFi pattern as scalable shapes, so one file prints sharp from a table tent to a poster.
- The encoded SSID, password and encryption are identical to a PNG — verify encryption before export, as vector can't fix a wrong setting.
Frequently asked questions
- Why export a WiFi code as SVG?
- Because WiFi codes usually become signage shown at several sizes — table tents, decals, posters. SVG is vector, so one file stays razor-sharp at every size with no re-export. PNG locks you to one resolution and blurs when enlarged, which fails on a bigger sign.
- Can I recolour a WiFi SVG to match my café?
- Yes. Open it in Illustrator or Inkscape and the modules are editable shapes you can tint to a brand colour or set on a transparent background. Just keep the code darker than its background, or the drop in contrast will stop phones from scanning it.
- Does SVG change how the WiFi code scans?
- No. The encoded data — SSID, password and encryption — is identical to a PNG, so a phone joins the network the same way. SVG only affects how the image is stored and printed, guaranteeing the pattern stays crisp at whatever size the sign is output.
- Why does my WiFi code scan but not connect?
- The encryption type in the code does not match your router, so the phone reads a valid code but refuses to join. Set the encryption field to WPA for a standard router and test on a real device before committing the vector to printed signage.
- Will an SVG WiFi sign work without an app?
- Yes, on modern phones. iPhones from iOS 11 and Androids from version 10 read a WiFi code with the built-in camera and show a join prompt. The SVG format does not change that — it only keeps the printed sign sharp at any size.
- Is an SVG file smaller than a printed-quality PNG?
- Usually. A WiFi code is a simple black-and-white pattern, and as vector it is often far smaller than a PNG rendered large enough to print a sign sharply. That keeps your signage artwork light and quick to hand to a printer.
