anyscan.download is a free browser-native web tool for creating, scanning, validating, batching and printing QR codes, barcodes and other machine-readable codes. There is no account, no watermark and no upload — the codes are built on your device, so whatever you encode stays there.
Paste text, a link or Wi-Fi details and the code appears as you type. Download PNG for screens or SVG for lossless resizing, while keeping printed modules or bars above the physical-size guidance.
Paste a list or upload TXT, CSV, TSV or XLSX. Map value, label, quantity, filename and format columns, then export safe PNG or SVG ZIPs with a row-level CSV report.
Read a QR code or barcode from PNG, JPEG, WebP, GIF, AVIF, BMP, SVG, HEIC/HEIF or TIFF, a pasted screenshot or your camera. Images up to 12 MB are decoded locally; the image and decoded value are not uploaded by anyscan.download.
Build A4, US Letter, custom or manufacturer-dimension-based Avery PDF sheets, correct measured printer scaling, or create local Zebra-compatible ZPL jobs using 203, 300, 600 or custom printer DPI.
Verify check digits and character rules, or assemble GTIN, expiry, batch or lot and serial fields into locally verified GS1-128 or GS1 Data Matrix output.
- Supported inputs
- Text, URLs, email addresses, phone numbers, Wi-Fi details, product identifiers, lists, spreadsheet columns, numbered sequences, and images containing existing codes.
- QR code inputs
- Plain text, links and Wi-Fi network credentials — WPA/WPA2, WPA3 (SAE), WEP or open, including hidden networks.
- QR code capacity
- For byte-mode data, up to 2,953 bytes at error-correction level L or 2,331 bytes at level M. Unicode characters may use more than one byte. Error correction is selectable: L, M, Q or H.
- Barcode formats
- Code 128, Code 39, EAN-13, EAN-8, UPC-A and ITF.
- GS1 output
- The guided builder creates GS1-128 and GS1 Data Matrix from GTIN (01), batch or lot (10), expiry date (17) and serial number (21), including required FNC1 separators.
- Check digits
- EAN-13, EAN-8 and UPC-A check digits are calculated for you from a 12-, 7- or 11-digit number, and verified when you supply the full code.
- Appearance
- Foreground and background colours, quiet zone from none to 8 modules, bar width and bar height are all adjustable.
- What “Verified scannable” means
- The tool renders the code, decodes that generated output locally, and compares the decoded value with the intended payload. It also checks contrast and quiet-zone guidance. This verifies the current digital output; printers, materials, lighting and scanners can still change the result, so test important physical runs.
- Download formats
- PNG and SVG for a single code; ZIP and CSV reports for batches; PDF for physical label sheets; and combined ZPL or individual ZPL ZIPs for supported Zebra printers.
- Batch limits
- Up to 50,000 rows and 50,000 quantity-expanded labels are validated per browser job. Image ZIP exports run in groups of up to 5,000 codes, and uploads may be up to 10 MB.
- Saved settings
- Batch mappings and label/printer presets can be stored in this browser or exported as JSON. Code values, spreadsheet rows and decoded content are deliberately excluded.
- Printer calibration
- Download a 100 mm A4 or US Letter reference, print at Actual size, measure both axes and apply uniform X/Y correction to generated PDF sheets. Skew and nonlinear printer distortion still require hardware or driver correction.
- Offline use
- After a successful online load, the site caches its static files for later offline use. Browser storage policies may remove cached files; advertising and other external scripts are not required for the tools.
- Where processing happens
- In your browser. Detection, generation, scanning and export all run on your device — the text you encode, the spreadsheets you upload and the values you decode are never sent to a server. The page still loads its own files and, when enabled, advertising from the network; the privacy page sets out exactly what that involves.
