How do QR codes work?
QR codes store data in a grid of black and white squares. When scanned, a camera reads the pattern and decodes the information—URLs, text, contact info, etc.

Utility Tools & Calculators
The grab bag: QR generators, text formatters, JSON pretty-printers, password strength testers, resume ATS analyzers, unit converters, percentage helpers. Quiet, fast, and they don't sell your inputs to anyone. Most live here because they came up in our own work and we got tired of opening a different site every time.
Sometimes you just need a tool that does one thing well. Our utility tools are the digital equivalent of a well-stocked toolbox: reliable, ready when you need them, and completely free. From converting text case to generating QR codes, these tools solve everyday problems quickly.
Text manipulation is something everyone needs occasionally. Whether you're formatting code, cleaning up copy-pasted text, or generating placeholder content for a design, having these tools a click away saves time. Our text tools run entirely in your browser, so your content stays private.
Job seekers will find our resume ATS analyzer particularly valuable. With most companies using applicant tracking systems to filter resumes before humans ever see them, understanding how your resume matches a job description can make the difference between getting an interview and getting filtered out.

Utility Tips & Best Practices
**Keep your resume under 2 pages** unless you have 15+ years of highly relevant experience. **Use keywords from the job description** naturally throughout your resume—ATS systems are looking for matches. **QR codes should be tested** on multiple devices before printing. **Save your work frequently** when using any online tool, even browser-based ones—browsers can crash.
Frequently Asked Questions
What is an ATS system?
Applicant Tracking Systems scan resumes before humans see them. They look for keywords, proper formatting, and relevant experience to filter candidates.
Why does my resume get rejected by ATS?
Common issues: unusual formatting, images/graphics, fancy fonts, tables/columns, missing keywords, and non-standard section headings.
Are online text tools safe to use?
Tools that run in your browser (like ours) don't upload your text to servers. Your content stays private. Avoid tools that require accounts or don't specify data handling.
What's the difference between character count and word count?
Character count includes every letter, number, space, and symbol. Word count is the number of words separated by spaces. Both are important for different contexts.
What keywords should I use in my resume?
Use exact phrases from the job description. If they say "project management," use that phrase rather than "managed projects." ATS systems often look for exact matches.
How many keywords should my resume have?
Aim for a 60-80% match rate with the job description. Include the most important keywords multiple times naturally throughout your experience and skills sections.
What file format is best for ATS resumes?
Simple .docx or plain text works best. PDFs can cause parsing issues with some ATS systems. Avoid complex formatting, tables, text boxes, and graphics.
