01
Roll a batch
Choose alphanumeric, hex, or numeric, set the length and count, and build up to 100 unique tokens at once.
CSPRNG randomness, bulk output
Random QR Code Generator
Generate up to 100 unique random QR payloads at once. Choose a character set and length, build the batch, and download PNGs or one ZIP — free, no sign-up, and generated locally in your browser.

How to Generate Random QR Codes in Bulk
Roll a batch, style it, download it — three steps.
02
Match your design
Pick a size and colors that fit your labels, tickets, or test sheets — keep the contrast high.
03

Common projects
What Random QR Codes Are Good For
Anywhere you need unique, unguessable codes at scale.
Scanner and print testing
Fill test sheets with fresh codes to calibrate scanners, printers, and scan-distance without reusing the same payload.
Unique tokens and coupons
Generate one-time voucher codes, giveaway entries, or access tokens — each QR encodes a different unguessable string.
Raffles and games
Print a pile of unique codes for prize draws, scavenger hunts, and escape-room puzzles.
Design placeholders
Drop realistic random codes into mockups and proofs before the real content is ready.
Character sets
Pick the Right Random Format
Three character sets, three trade-offs between density and readability.
Alphanumeric, hex, or numeric
Alphanumeric is compact and avoids look-alike characters (no 0/O or 1/I); hex suits technical IDs; numeric-only scans fastest and works in numeric-only fields.
Optional file names
Use Name,Value on a line to give its PNG a useful file name, or keep automatic numbered names.
PNG and ZIP downloads
Download one PNG from its preview or package every generated PNG into one ZIP file.
Randomness comes from your browser's crypto-grade generator (crypto.getRandomValues) — codes never leave your device.
Before production
Check Your Random Codes Before Printing
Random codes are only useful if you can trace them back.
Keep the list
Save the generated token list alongside the QR codes — a random code with no record of what it was assigned to is just noise.
Test with real phones
Scan samples with more than one phone or camera app, especially after resizing or placing them in a layout.
Protect contrast and spacing
Keep a clear quiet zone around each code and use strong contrast between the foreground and background.
Match length to purpose
Longer tokens are harder to guess but make denser codes — 8-12 characters is plenty for most vouchers and test sets.
Frequently Asked Questions
Answers about what random QR codes are, uniqueness, security, use cases, batch limits, and expiration.
What is a random QR code?
A random QR code encodes a randomly generated text payload instead of a link you typed. The QR's visual pattern is simply the rendering of that payload; this page randomizes the content, not a decorative QR design.
Does random mean a random QR design?
No. Random QR codes here mean random payload tokens: the text inside each code changes. The visual design still follows the QR standard and your selected size and colors, so the code can be scanned.
Are the generated codes truly unique?
Each token is generated in your browser with crypto.getRandomValues, a cryptographically secure random number generator (CSPRNG), and duplicates are rejected within the batch. At the default 12-character alphanumeric length there are over 10^21 possible values, so accidental duplicates among 100 are extremely unlikely.
Is this random QR generator secure and private?
Everything runs locally in your browser using crypto.getRandomValues, a CSPRNG suitable for generating unpredictable tokens. No codes, inputs, or downloads are sent to a server. This tool does not save or validate tokens in a database, so keep your exported list if you need an assignment record.
What can I use random QR codes for?
Common uses: testing scanners and printers with fresh payloads, printing one-time coupon or voucher codes, running raffles and scavenger hunts, issuing unique access tokens, and filling design mockups with realistic codes.
How many random QR codes can I make at once?
The random-code builder accepts 1-100 tokens per batch, with token lengths from 4-64 characters. You can download individual PNGs or one ZIP. Need more? Build another batch; each roll is independent.
Do random QR codes expire?
No. They're static codes with the token baked in — they scan forever with no account or subscription. What the code means is up to your own system or record-keeping.
