Free Utility Tools — QR, Passwords & Resumes

The Utility category at TaimurTools collects six everyday helpers that don't fit neatly into the image, PDF, AI, or media buckets. The QR Code Generator turns any URL or text into a high-resolution PNG ready for print. The Social Media Cropper resizes any image to the exact aspect ratio for Instagram, Twitter/X, LinkedIn, Facebook, or YouTube. The Password Checker scores password strength locally without sending anything to a server. The Resume Builder produces a clean ATS-friendly markdown-based resume you can export to PDF. The LinkedIn Optimizer rewrites your headline and About section for higher recruiter visibility.

Three of the six (QR Code, Cropper, Password Checker) run entirely in your browser with no network calls. Resume Builder stores your draft in browser localStorage so you can come back later, and only contacts the AI inference API when you click Generate. LinkedIn Optimizer is AI-powered end to end. All six are free with no signup, no watermark, and no daily limit. Below you will find every tool with a short description and a launch link, then five FAQs covering the questions users ask most often about this category.

All Utility tools

QR Code Generator

Create QR codes for URLs and text. Paste any link, message, contact card, or Wi-Fi credential, click Generate, and download a high-resolution PNG. The output supports print up to A2 size with no quality loss. Choose foreground and background colours, error correction level, and embedded logo if needed. Codes work in every QR scanner including the camera apps on iOS and Android. Generation runs locally in your browser — your input never leaves the page, which matters when the QR encodes private content like Wi-Fi passwords or contact details.

Social Media Cropper

Crop images for Instagram, Twitter, etc. Drop in any image and the tool offers presets for every major platform: Instagram square (1:1), Instagram portrait (4:5), Instagram Story (9:16), Twitter/X header (3:1), LinkedIn cover (4:1), Facebook post (1.91:1), YouTube thumbnail (16:9), TikTok (9:16). Drag the crop frame to reposition, then export as PNG or JPG. Output dimensions match each platform's recommended size exactly so your image fills the frame without algorithmic re-cropping. Processing runs in-browser via the Canvas API; the original file never gets uploaded.

Password Checker

Check password strength and security. Type a candidate password and the tool returns an instant strength score from Very Weak to Very Strong, an estimated time to crack via brute force, and a checklist of weaknesses (too short, common dictionary word, no special character, contains personal information patterns). Analysis runs 100% in your browser with zero network calls — the password is never logged, transmitted, or compared against a remote breach database. For breach checking specifically, use HaveIBeenPwned, which uses a privacy-preserving k-anonymity API.

Resume Builder

Build a professional resume in minutes. Fill in sections — contact, summary, experience, education, skills, projects — and the tool renders a clean ATS-friendly resume in real time. Export to PDF for emailing or to plain markdown for editing in any tool. Drafts auto-save to browser localStorage so you can come back later without losing work. The optional AI assist rewrites bullet points to be more impact-focused (replaces "responsible for managing team" with "led 8-person team to deliver project two weeks ahead of schedule"). No signup, no daily limit, no template watermark.

LinkedIn Optimizer

Optimize your LinkedIn profile with AI. Paste your current headline, About section, and a few experience bullets; the AI rewrites each piece for higher recruiter visibility and more keyword relevance. Output includes three headline variants, a rewritten 200-word About paragraph, and 5 keyword suggestions for your skills section. The tool follows current LinkedIn algorithm preferences (concrete numbers, role-specific keywords, first-person voice, soft hooks at the start of long posts). Free, no signup. Your existing profile content is sent to the AI for rewriting; nothing is stored on TaimurTools' servers.

Smart Image-to-UI Component

Turn a UI screenshot or sketch into React or Tailwind CSS code. Upload a design mockup, a screenshot of a layout you like, or a hand-drawn wireframe, and a free AI vision model maps it to production-ready component code you can paste straight into a project. Output covers structure, spacing, and Tailwind utility classes, so front-end work starts from a working component instead of a blank file. The image is sent to a free AI vision API for analysis, so avoid screenshots containing confidential data. Free, no signup, no daily limit.

Frequently asked — Utility tools

Are these utility tools really free?

Yes. All six utility tools are free with no signup and no daily limit. The QR code generator, social media cropper, and password checker run entirely in your browser. Resume Builder, LinkedIn Optimizer, and Smart Image-to-UI Component use a free AI inference API for content generation.

Are my passwords or resume data sent anywhere?

Passwords entered into the password checker never leave your browser — strength analysis runs locally with zero network calls. Resume Builder keeps the document in browser localStorage; only the AI generation step sends content to the inference API and only for the prompt you submit.

Can I use the QR codes commercially?

Yes. QR codes are an open standard, not subject to licensing. You can print them on packaging, business cards, posters, menus, or product labels. Output is high-resolution PNG with transparent or solid background, which is suitable for print up to A2 size.

Which browsers are supported?

Any modern browser: Chrome 90+, Edge 90+, Firefox 88+, Safari 14+, including their mobile versions. The tools use standard Web APIs that have been stable for years, so even older browsers usually work.

Can I save my resume draft and come back later?

Yes. The Resume Builder auto-saves your draft to browser localStorage every few seconds. As long as you return to the tool from the same browser without clearing site data, your work persists indefinitely. For permanent backup, export to PDF or copy the markdown source into a personal note.
