Barcode Generator
Type a value, barcode updates live
Code128 accepts any text. EAN13/EAN8/UPC/ISBN13 require specific digit counts.
What Is a Barcode Generator?
A barcode generator turns a piece of text or a number into a scannable barcode image. Type a value above and pick a barcode type — the image updates live, no button to press.
How to Create a Barcode
Type the value you want to encode.
Pick a barcode type from the dropdown.
Press "Download PNG" to save it.
Is This Barcode Generator Free?
Yes — there's no paywall, no watermark, and no sign-up required.
Which Barcode Type Should I Use?
Use Code128 if you just need to encode any text or number with no format restrictions. Use EAN13, EAN8, UPC, or ISBN13 only if you specifically need a barcode that matches one of those real product or book numbering standards.
Code128: The Flexible Barcode
Code128 accepts almost any text — letters, numbers, and most symbols — with no fixed length. It's the right default when you're labeling something internal, like inventory or asset tags, rather than encoding a standardized retail number.
EAN, UPC, and ISBN Barcode Requirements
- EAN13 — 12 or 13 digits
- EAN8 — 7 or 8 digits
- UPC — 11 or 12 digits
- ISBN13 — a 13-digit ISBN
These formats are strict about length because real-world scanners expect an exact digit count — enter the wrong number of digits and generation fails with an error telling you what's expected.
Downloading Your Barcode
Press "Download PNG" once a barcode is showing — it saves as a plain image with the human-readable value printed underneath the bars, ready to print or drop into a label.
Can I Generate Barcodes in Bulk?
Not on this tool — it generates one barcode at a time as you type. For a batch of many different values, you'd need to generate and download each one individually, or use a dedicated bulk tool.
Is It Safe to Use This Barcode Generator?
Yes — the value you enter is used to generate the image for that request and isn't saved anywhere. No account or sign-up is required to use it.

Frequently Asked Questions About Barcodes
Is this barcode generator actually free?
Yes — there's no paywall, no watermark, and no sign-up required.
Which barcode type should I use?
Code128 if you just need to encode any text or number with no format restrictions. EAN13, EAN8, UPC, or ISBN13 if you need a barcode that matches a real product or book numbering standard.
Why does it say my input is invalid?
EAN13, EAN8, UPC, and ISBN13 require an exact digit count (for example, EAN13 needs 12-13 digits). Code128 and Code39 accept flexible text, so switch to one of those if your value doesn't fit a strict format.
Can I generate barcodes in bulk?
Not on this tool — it generates one barcode at a time. For a batch, you'd need to generate and download each value individually.
Does the barcode include readable text?
Yes, the human-readable value always prints underneath the bars.
Do you store what I encode?
No. The value you enter is used to generate the image for that request and isn't saved anywhere.
