About this category

About Generators

FindUtils provides generator tools for QR codes, barcodes, UUIDs, digital signatures, email signatures, social media content, lorem ipsum text, placeholder images, and JSON-driven cards, charts, invoices, and resumes. Popular generators include the QR Code Generator with PNG and SVG output, the Barcode Generator with five formats (Code 128, Code 39, EAN-13, EAN-8, UPC-A), the UUID Generator with v4, v7, v1, and nil, and the Email Signature Generator with HTML export. Every generator on this page runs in your browser. FindUtils.com is not the GNU findutils package.

Frequently Asked Questions

Can I customize the generated QR codes?

Yes, within what the tool offers. You can set the foreground and background colors, the size from 100 to 1000 pixels, and the quiet-zone margin. The generator encodes five content types: a URL, plain text, an email address, Wi-Fi credentials, and a vCard contact. Error correction is fixed at level M, which survives about 15 percent damage. There is no logo embedding, and no phone or SMS type. Output formats are PNG and SVG.

Can I use the generated output commercially?

Yes. Everything generated by FindUtils tools is yours to use for any purpose, including commercial use, without attribution, licensing fees, or restrictions. QR codes, barcodes, UUIDs, email signatures, lorem ipsum text, invoices, social media cards, and all other generated content are available for commercial projects, client work, marketing materials, product packaging, business cards, and any other use case. FindUtils does not claim any intellectual property rights over generated content. You can use the tools to create assets for your business, generate content for clients, produce materials for resale, or any other commercial application. There are no hidden terms and no premium commercial license.

Can I generate content from my own data?

Yes. Several FindUtils generators turn your own data into formatted output. The JSON-to-card generators turn JSON into product, profile, social and testimonial cards. JSON to Invoice turns line items into an invoice you download as PNG or copy as HTML; the Finance hub's Invoice Generator makes PDFs. JSON to Resume turns your career details into a resume layout, and the Email Signature Generator turns your contact details into an HTML signature. Spreadsheet data is handled under Converters (findutils.com/convert/), for example CSV Viewer and JSON to CSV. On these pages your input is processed in your browser and not uploaded; like the rest of FindUtils, the pages also load analytics and ad scripts.

Do the generators save my data?

No. Every generator on this page processes your input in your browser with client-side JavaScript. The tool code does not send what you type to a server, and nothing you enter is stored in a database. Some tools keep your preferences or recent items in your browser's local storage on your device, and a reset button or your browser settings clear it. The pages do load analytics and ad scripts, as most websites do, so a network monitor shows requests from those scripts. They are separate from the tool code. If you handle confidential material, open the page in a private window with a content blocker, and every generator still works.
