Hello Tools is a simple and helpful website made for people who want fast online tools without confusion. It offers many free tools for converting files, compressing images and PDFs, and improving SEO work. The best part is that everything works directly in your browser. Your files never leave your device, which means better privacy and better speed.

What Is Hello Tools and Who Is It For

Hello Tools is designed for bloggers, developers, designers, marketers, students, and everyday users. If you need to resize an image, convert it to WEBP, compress a PDF, or generate SEO items like UTM links and slugs, Hello Tools makes it easy. You do not need to sign up, install software, or upload files to a server.

Image Conversion and Compression Made Easy

One of the most popular features of Hello Tools is image conversion. You can convert images to WEBP, resize them in pixels, and reduce file size without losing quality. This is very useful for websites because smaller images load faster and improve user experience. Faster loading also helps your website rank better in search engines.

Why WEBP Is a Smart Choice

WEBP is a modern image format created to make images smaller while keeping good quality. Compared to JPEG and PNG, WEBP files are lighter and faster to load. This helps your website performance and improves Core Web Vitals. Hello Tools supports both lossy and lossless WEBP compression. It also supports transparency and animation, which makes it perfect for modern web design. Most browsers today fully support WEBP, so it is safe to use.

PDF Compression and SEO Utilities

Hello Tools also allows you to compress PDF files quickly. This is helpful when you need to share documents by email or upload them online. Smaller PDFs are easier to download and store. For SEO work, Hello Tools includes generators for UTM links, slugs, UUIDs, and more. These tools help you track marketing campaigns and keep your URLs clean and readable.

Powerful Hash Calculator for Everyday Use

Another strong feature of Hello Tools is its hash calculator. This hash calculator allows you to compute MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes for both text and files. Many users look for a hash value calculator to verify file integrity, and Hello Tools makes this process simple.

You can use this hash calculator online without worrying about privacy because it works fully offline in your browser. This online hash value calculator also supports optional HMAC, HEX, and Base64 output formats. For advanced users, bulk file hashing is available, saving time when checking multiple files.

Understanding Hashing in Simple Words

Hashing means converting data into a fixed-length value called a hash. A hash value calculator is often used to check if a file has been changed or damaged. Developers and security professionals also use hashing for authentication through HMAC. For new projects, it is always better to use strong algorithms like SHA-256 or higher. Hello Tools makes this process easy even for beginners.

Privacy First: Your Data Stays With You

Many people worry about uploading files to unknown websites. Hello Tools solves this problem by running everything locally in your browser using HTML Canvas and modern web technology. Your images, PDFs, and text are never uploaded or stored. Nothing leaves your device, which means full privacy and peace of mind.

File Size Limits and Performance Tips

There is no strict file size limit, but for best performance, Hello Tools recommends using images under 50MB. Larger files can still work, depending on your device power and browser. Keeping files smaller will always give you faster results.

Future Updates and More Formats

Hello Tools is constantly improving. If you need a new format or feature, you can request it. New tools and formats can be added easily, and the grid updates without breaking existing tools.
