Web tools
11 toolsBuild and pick apart URLs, generate QR codes and barcodes, look up MIME types and HTTP status codes, and plan IP subnets. The small lookups and encoders you need mid-task, without opening yet another platform.
Like everything on loot.tools, these run entirely in your browser. Free, no account, and nothing you enter leaves the tab.
Which one do you need?
The URL tools split by task. URL Builder & Parser assembles a URL from its parts or breaks a pasted one apart, with every query parameter in its own row. URL Encoder/Decoder percent-encodes and decodes strings, and Slug Generator turns a headline into a clean, hyphenated path segment.
Two generators make scannable codes: QR Code Generator for links, text, and Wi-Fi credentials, and Barcode Generator for retail and logistics formats like EAN-13 and Code 128. Meta Tag Generator belongs with them as the page-facing one, writing the Open Graph and Twitter tags that decide how a link previews when shared.
The lookups earn their keep mid-debugging. HTTP Status Codes explains every status code with causes and fixes, MIME Type Lookup maps file extensions to content types and back, and User-Agent Parser decodes a browser's user-agent string. For networks, IP Subnet Calculator does the CIDR math and IP Address Converter rewrites an IPv4 address as integer, hex, binary, or IPv6.
