Libre Barcode Project
Points and comments are a snapshot, not live.
Libre Barcode fonts let users write Code 39, Code 128, and EAN/UPC barcodes via typeface.
The project provides free fonts for generating barcodes in Code 39, Code 128, and EAN/UPC formats. A hosted encoder computes start, stop, and checksum characters for scannable output. The Code 128 Encoder page includes an optimizing encoder that switches between Code Sets A, B, and C to produce the shortest barcode. Fonts render with or without human-readable text below the code.
What commenters are saying
Two camps emerged: one celebrating the technical cleverness (citing prior work like Bad Apple and llama.ttf), the other warning against barcode fonts due to scanner compatibility issues and the ease of generating vector barcodes directly. A commenter noted the EAN13 checksum is computed automatically by the font using OpenType features, though Code 128 requires an external encoder. Several recommended using printer-native barcode support or libraries like Zint instead.
