Work smarter with one compact toolkit

Free Digital Utilities is a free, all-in-one web toolkit that provides essential digital tools in one convenient location. All tools run entirely in your browser, ensuring privacy and security. No sign-ups, no data collection, and no server-side processing for most features.

Yes, all tools are completely free to use. There are no hidden fees, subscriptions, or premium tiers. Simply visit the website and start using any tool immediately.

Absolutely! All tools process data locally in your browser. We don't collect, store, or transmit your personal information, files, or generated content to our servers. Your privacy is our top priority.

No account creation is required. You can use all tools immediately without any registration. Just open the tool you need and start using it right away.

The signature tool provides a canvas where you can draw your signature using your mouse, touchpad, or touchscreen. You can customize the stroke color and width. Once drawn, you can export your signature as PNG, JPG, or PDF format. All processing happens in your browser - your signature is never uploaded to any server.

You can export your signature in three formats: PNG (for web use), JPG (compressed image), and PDF (for documents). The PDF format maintains the exact dimensions of your signature canvas.

Yes! Once you download your signature, you can insert it into any document, email, or form. The PNG and JPG formats work well for digital documents, while PDF format is ideal for official documents that require precise formatting.

Simply enter any text or URL you want to encode into a QR code. You can adjust the size (100-600 pixels). The tool generates a QR code that can be scanned by any QR code reader. The generator uses reliable encoding algorithms to ensure your QR codes scan correctly every time.

You can encode URLs, text messages, contact information, WiFi credentials, or any plain text. QR codes are commonly used for sharing website links, but they can store any text-based information.

Yes! Once generated, you can download your QR code as a PNG image file. The downloaded QR code maintains high quality and can be printed or shared digitally.

The converter allows you to select one or more image files (JPG, PNG, etc.) and merge them into a single PDF document. All processing happens in your browser - your images are never uploaded to any server. The converter processes images at 72 DPI, which is standard for screen viewing.

The converter supports all standard image formats including JPG, JPEG, PNG, GIF, BMP, and WebP. You can select multiple images and they will be combined into a single PDF in the order you selected them.

Yes! All image processing happens entirely in your browser using JavaScript. Your images never leave your device and are never transmitted over the internet. Once you close the page, the images are cleared from memory.

The password generator creates cryptographically strong random passwords based on your preferences. You can customize the length (8-64 characters) and choose which character sets to include: uppercase letters, lowercase letters, numbers, and symbols. The tool includes a strength indicator to help you create secure passwords.

The passwords are generated using the browser's built-in cryptographically secure random number generator. This ensures that passwords are truly random and unpredictable. The strength indicator helps you understand how secure your password is based on length and character variety.

No! Passwords are generated entirely in your browser and displayed only on your screen. They are never stored, logged, or transmitted over the internet. You can copy them to your clipboard or regenerate new ones as needed.

The tool integrates with Mailinator, a public email service. You can create a temporary email address with a custom alias (or use the auto-generate feature). Any emails sent to this address will appear in the Mailinator inbox, which you can access directly from our tool. Perfect for sign-ups, testing, or protecting your real email address.

Mailinator inboxes are public and temporary. Emails typically remain accessible for a limited time (usually a few hours to a day). These emails are ideal for one-time verifications or testing, not for long-term use or sensitive communications.

Temporary emails via Mailinator are public inboxes, meaning anyone with the email address can view the messages. They're great for public sign-ups and testing, but should not be used for sensitive or private information. Always use your regular email for important communications.

The speed checker sends a request to the URL you specify and measures the response time. It uses a public proxy service to avoid CORS (Cross-Origin Resource Sharing) restrictions. The tool displays response time, file size, server information, content type, and cache headers to help you understand website performance.

The test measures the time it takes for a website to respond to a request (in milliseconds), the size of the response, server type, content type, and cache settings. This gives you a quick overview of basic performance metrics.

Many websites have CORS policies that prevent direct requests from other domains. The proxy allows us to make the request on your behalf, enabling you to test any URL regardless of its CORS settings.

All modern browsers are supported including Chrome, Firefox, Safari, Edge, and Opera. The tools use standard web technologies and work on desktop, tablet, and mobile devices. Some features may require JavaScript to be enabled.

Most tools work offline after the initial page load. The Digital Signature Generator, Password Generator, and PDF Converter can work completely offline. However, the QR Code Generator (remote API mode), Temporary Email, and Speed Checker require an internet connection.

File size limits depend on your browser's memory capacity. For the PDF converter, we recommend keeping individual images under 10MB for optimal performance. The signature generator works best with canvas sizes up to 900x320 pixels. Very large files may cause performance issues.
