A collection of fast, reliable, and privacy-focused utilities. Generate QR codes, shorten URLs, format text, validate JSON, and more — all directly in your browser.
Create custom QR codes for URLs, plain text, vCard contacts, WiFi credentials, and email addresses. Download in PNG or SVG format with adjustable size and error correction levels.
Convert long URLs into compact, shareable links. Track click statistics, set expiration dates, and manage all your shortened links from a single dashboard.
Transform text with case conversion (upper, lower, title, sentence), remove duplicate lines, sort alphabetically, trim whitespace, and count characters, words, or sentences.
Pretty-print JSON with syntax highlighting, validate structure and identify errors with helpful messages, minify for production use, and convert between JSON and YAML formats.
Encode text or files to Base64 strings for safe embedding. Decode Base64 back to original format. Supports UTF-8 text, images, and binary file conversion.
Generate cryptographic hashes including MD5, SHA-1, SHA-256, and SHA-512 from text input. Useful for data integrity verification, password hashing, and checksum validation.
Write Markdown in a live editor with real-time HTML preview. Supports headings, lists, tables, code blocks, images, links, and GitHub-flavored Markdown extensions.
Convert colors between HEX, RGB, HSL, and HSV formats. Pick colors with a visual palette, generate complementary and analogous color schemes, and preview accessibility contrast ratios.
Convert Unix timestamps to human-readable dates and vice versa. Supports multiple time zones, relative time display (e.g., "3 hours ago"), and batch conversion of multiple values.
All processing happens in your browser. No server round-trips needed.
Your data never leaves your device. Zero tracking, zero analytics.
Use all tools instantly. No sign-up, no email, no account required.

QuickTools was built with a simple philosophy: useful tools should be free, fast, and respectful of your privacy. Every utility on this site runs entirely in your browser using client-side JavaScript, which means your data is never uploaded to any server.
Whether you're a developer debugging JSON, a designer picking colors, a marketer generating QR codes, or just someone who needs to quickly convert a timestamp, QuickTools has you covered. We add new tools regularly based on user feedback.
All tools are open for use without any limitations. No hidden paywalls, no watermarks, no daily quotas. Just straightforward utilities that work.
