Easy 128 Bulk Code Generator 제작자: Sirlukethegreat

Generate Code 128 barcodes in bulk without leaving the page you are on.
Click the toolbar button and a panel opens on the right. Paste your codes, one per line, and hit
Generate. There is no cap on how many you can do at once, and rendering happens in batches so a
large paste will not lock up the tab.
Features
Bulk generation, one code per line, no limit
Grab selection: pulls text you have highlighted on the page straight into the box
Auto-fit, which scales every barcode so the longest one fills the panel, and recalculates when
you resize
Ignore duplicates, so repeated lines only render once
Adjustable bar height and module width
Optional human readable text under the bars
Resizable panel, remembers your settings between sessions
Everything runs locally in your browser. No account, no server, no network requests, no tracking.
Your codes are never sent anywhere.
Code 128 details
Full auto mode switching between Code B and Code C, which roughly halves the barcode length for
numeric data. Mod 103 checksum. Standard 10 module quiet zones so the output actually scans.
Accepts any ASCII character from 32 to 126. Anything unsupported gets flagged on its own line
instead of silently failing.
Notes
The panel cannot open on Firefox internal pages such as about:newtab or about:debugging, or on
addons.mozilla.org. Firefox blocks extensions from running there.
