ZapTools is a free collection of online utilities at zaptools.net. Writers, marketers, developers and students use it to clean text, check a certificate, build a meta tag or hash a string, without installing software and without creating an account.
Tools that stay in the browser
Most tools run on your device. The text, numbers and images you enter are not sent to ZapTools and are not stored. That covers word and character counters, case conversion, JSON and HTML formatters, hashes, passwords, QR codes, and SEO helpers such as the meta tag generator and the keyword density check.
What you can do
- Text — count words, sort and clean lines, encode a URL, test a regular expression, or turn a title into a slug.
- Calculators — VAT, percentages, dates between two days, and IPv4 subnets.
- Design — pick a color, preview a responsive page, or convert an image to Base64.
- Marketing and SEO — preview a Google ad, suggest keywords, write robots.txt, and generate meta tags.
- Utilities — check SSL, ping a host, shorten a URL, create a UUID, convert Unix time, decode a JWT, or explain a cron expression.
Eight languages
Every public page is available in English, Spanish, German, Portuguese, Italian, French, Hindi and Vietnamese. Use the language menu in the header. Each version has its own title, description and canonical URL on zaptools.net.
