DLEncoder

什麼是 DLEncoder？

DLEncoder generates AAMVA-compliant PDF417 barcodes — the data on the back of US driver licenses and IDs — for engineering and QA testing. Unlike other tools, it requires no signup and gives full control over every field and jurisdiction subfile. Covers both the v10 and the new v11 (2025 CDS) standards. It also decodes and diagnoses real scans, flagging preamble, CRLF, and length issues. Runs entirely in your browser — nothing uploads. Free.
