Tips for better results
Double-check that your input matches what barcode generator expects — for example the correct file type for uploads, or well-formed text for formatters and validators. If something fails, read the error message, fix the input, and try again.
For document workflows, keep an original master copy when compressing or converting for email. For text tools, paste only what you need and clear sensitive snippets from your clipboard afterward when working on a shared machine.

FAQ
Which format should I use?
Code 128 works for most general text. Use EAN-13/UPC for retail products that need those standards.
Why did generation fail?
EAN and UPC need the correct number of digits. Check the hint under the value field.
