50+ free developer tools including PDF tools, QR scanner, OCR, converters, text tools, math calculators, hash generators and more. All tools run locally in your browser.
Empowering developers, students, and everyday users with free, fast, and privacy-friendly online tools.
ProToolsHub is a comprehensive online platform offering more than 50 free tools designed to help people accomplish everyday digital tasks quickly, accurately, and securely. From PDF conversion and QR code generation to mathematical calculators, unit converters, text utilities, and security tools, everything on this website works instantly in your browser — with no installation, no registration, and no cost. Our mission is simple: make powerful, professional-grade tools accessible to everyone, everywhere, for free.
ProToolsHub was created with a simple observation: most online tools are either locked behind paywalls, require unnecessary sign-ups, upload your files to unknown servers, or bombard you with intrusive ads and slow loading times. We believed there had to be a better way. So we built a platform where every single tool runs entirely on the client side — inside your own browser — using modern web technologies. This approach eliminates server delays, protects your privacy by design, and makes our tools lightning fast. What started as a small collection of developer utilities has grown into a complete toolbox serving thousands of users who need reliable tools for work, study, and personal projects.
Our toolbox covers eight major categories. PDF & Document Tools: PDF to Text, Image to PDF, PDF to JPG, Word to PDF, HTML to PDF, Text to PDF, and Batch Image to Text (OCR). Text & Encoding Tools: JSON Formatter, Base64 Encode/Decode, URL Encode/Decode, HTML Encode/Decode, Word Counter, Text Reverser, Slug Generator, and Morse Code Encoder/Decoder. Math & Calculators: BMI, Discount, Age, Simple Interest, Compound Interest, GCD & LCM, Prime Checker, Factorial, and Average Calculator. Unit Converters: Length, Weight, Temperature, Speed, Data Storage, Currency (30+ world currencies), Area, and Volume. Date & Time: Unix Timestamp, Date Difference, and Leap Year Checker. Security Tools: SHA-256 Hash, MD5 Hash, Password Generator, and Password Strength Checker. CSS & Design Tools: Color Converter, Border Radius Generator, and CSS Gradient Generator. Data Tools: CSV to JSON and JSON to CSV converters, plus QR Code Generator and QR Code Scanner.
Developers use our tools for formatting JSON, generating hashes, encoding data, and creating CSS snippets. Students rely on our calculators for math homework, unit conversions for science projects, and text tools for assignments. Teachers use our tools to prepare learning materials and verify calculations. Content writers and SEO professionals count words, generate URL-friendly slugs, and optimize their content. Business professionals convert documents, generate QR codes for marketing, and calculate interest for financial planning. Designers convert colors between formats and generate gradient and border-radius CSS. Whatever your role, there is something here for you.
Your privacy is our top priority. Unlike many online tools that upload your files to remote servers where they may be stored, logged, or analyzed, every tool on ProToolsHub processes your input directly in your browser using JavaScript. This means your PDF documents, images, passwords, text, and personal data never leave your device and never touch our servers. We believe you should never have to trade your privacy for convenience, and our entire platform is built around that principle.
We use proven, industry-standard open-source libraries to power our tools, including PDF.js for document parsing, jsPDF for PDF creation, Tesseract.js for optical character recognition, and the Web Crypto API for cryptographic operations. These libraries run in your browser, which is why our tools are both fast and private. Our website is lightweight, mobile-friendly, and optimized for performance so it loads quickly even on slow connections.
We are continuously improving ProToolsHub based on user feedback. New tools are added regularly, existing tools are refined, and the overall experience is constantly being polished. If there is a tool you would love to see on our platform, we would genuinely love to hear from you — your suggestions directly shape our roadmap.
Have a question, suggestion, or feedback? We would love to hear from you. Email us anytime at support@protoolshub.online and we will get back to you as soon as possible.
We love hearing from our users! Whether you have a question about one of our tools, want to report a bug, have a suggestion for a new feature, need help with something that is not working as expected, or just want to share feedback about your experience — our inbox is always open and every message is read personally.
Before you write: many common questions are already answered in the FAQ section below and in the detailed guides available on every tool page. If your question is about how a specific tool works, open that tool and scroll down to the step-by-step instructions — chances are the answer is already there.
Fill out the form below and we will do our best to respond within 24–48 hours on business days. Please include as much relevant detail as possible (for bug reports: the tool name, your browser and device, and what you expected versus what happened) so we can help you faster.

ProToolsHub ("we", "our", or "us") operates this website. This Privacy Policy explains what information we collect, how we use it, how we protect it, and what choices you have regarding your information when you use our website and tools. By using our website, you agree to the practices described in this policy. If you do not agree with this policy, please discontinue use of the website.
The most important thing to know about ProToolsHub is that all tools process your data locally in your browser. When you use our PDF converters, text tools, calculators, hash generators, or any other utility, your files and input are processed entirely on your own device using JavaScript. Your documents, images, passwords, and text are never uploaded to our servers, never stored by us, and never shared with anyone. This is not just a policy — it is how the website is technically designed.
When you contact us through our contact form or by email, you may provide us with personal information such as your name, email address, and the content of your message. We use this information solely to respond to your inquiry. Providing this information is entirely voluntary.
Like most websites, our servers and analytics tools may automatically collect limited technical information when you visit, including your IP address, browser type and version, device type, operating system, referring pages, pages visited, and the date and time of your visit. This information is used in aggregate form to understand how the website is used and to improve performance and content. It is not used to personally identify you.
We use cookies — small text files stored on your device — for the following purposes:
You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent. Most browsers allow you to manage cookies through their settings. Note that refusing essential cookies may affect how some parts of the website function.
The limited information we collect is used for the following purposes: providing, operating, and maintaining the website; responding to your messages and support requests; understanding how visitors use the website so we can improve tools and content; detecting, preventing, and addressing technical issues and abuse; and complying with legal obligations. We do not sell, rent, or trade your personal information to third parties for their marketing purposes.
We use Adsterra as our advertising partner to display ads on this website, which allows us to keep all tools free. Adsterra and its partners may use cookies, web beacons, and similar technologies to serve ads based on your prior visits to this website or other websites, and to measure advertising effectiveness. These technologies are governed by Adsterra's own privacy policy. Third-party ad servers or ad networks may automatically receive your IP address when ads are displayed. We do not control the cookies used by third-party advertisers. You can manage personalized advertising preferences through your browser settings or industry opt-out tools such as the Network Advertising Initiative opt-out page.
If Google Analytics is enabled on this site, it uses cookies to collect anonymous usage statistics such as page views, session duration, approximate geographic region, and device information. This data is processed by Google under its own privacy policy and is used by us only in aggregate form to improve the website. You can opt out of Google Analytics by installing the official Google Analytics Opt-out Browser Add-on.
Because tool inputs are processed locally in your browser, we do not retain the content you process with our tools. Contact form messages and emails are retained only as long as needed to respond to you and maintain records of our correspondence. Server logs are retained for a limited period for security and troubleshooting purposes and are then deleted.
We use commercially reasonable technical and organizational measures to protect the website and any information under our control, including HTTPS encryption for all traffic, secure session handling, CSRF protection, and rate limiting on sensitive endpoints. However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security. That said, our client-side architecture means the most sensitive data — your files and tool inputs — never leaves your device in the first place.
Our website is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will delete such information promptly.
Depending on your jurisdiction, you may have rights regarding your personal data, including the right to access, correct, delete, or restrict the processing of your personal information, and the right to object to certain processing. Because we collect very little personal data, most of these rights are exercised simply by contacting us. You may also: disable cookies through your browser settings; opt out of personalized advertising through industry opt-out tools; and stop using the website at any time. If you are located in the European Economic Area, you also have the right to lodge a complaint with your local data protection authority.
Our website may contain links to third-party websites or services that are not operated by us. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites or services. We encourage you to review the privacy policy of every site you visit.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this page periodically. Your continued use of the website after changes are posted constitutes your acceptance of the updated policy.
If you have any questions about this Privacy Policy or our data practices, please contact us at support@protoolshub.online.

Nothing on this website constitutes, or should be interpreted as, professional advice of any kind. Specifically:
Automated tools can produce unexpected results due to rounding, unusual input, browser differences, or limitations of the underlying libraries. File conversions may not perfectly preserve formatting. OCR results depend heavily on image quality. We recommend reviewing all outputs before using them for any important purpose, and verifying critical figures (measurements, dates, conversions, and calculations) independently.
