All Tools
Every ZillaKit tool, grouped by category — free and running in your browser.
ZillaKit is a growing collection of free online tools that run entirely in your browser. From compressing images and merging PDFs to generating QR codes, transcribing audio, building printable puzzles and crunching everyday numbers, every tool works instantly — no sign-up, no watermarks and no upload, so your files stay on your device. This page is the complete directory: every tool we make, grouped by category so you can browse the whole toolkit at a glance. Use the search box to jump straight to what you need, or tap a category to leap down to its section. Teachers, developers, contractors, creators and curious minds all have a home here. Everything is free, and new tools land regularly.
🖼️ Image Tools 22 tools
Image tools cover the jobs that normally mean installing software: converting between PNG, JPG, WebP and HEIC, shrinking a photo so it fits an upload limit, cropping, resizing, adding text, removing a background or building a favicon pack. The work happens on the picture already open on your device, so a family photo or an unreleased product shot never leaves your machine. Anyone who posts, prints or emails pictures ends up needing one of these.
📁 PDF & Files 20 tools
PDF and file tools handle the paperwork side of owning a computer: merging several documents into one, splitting a long scan, rotating or deleting pages, adding a signature, stamping a watermark, compressing a file until it fits an email, and converting between PDF and common office formats. Most of it runs in the page itself. Small businesses, students, landlords and anyone dealing with forms use these more than any other group.
🧮 Calculators 9 tools
Calculators answer the questions people usually reach for a phone to work out: what percentage one number is of another, what a loan repayment comes to over its term, how many days sit between two dates, what a measurement is in other units, what a tip or a discount leaves you with. Each one shows the numbers it used rather than only the answer, so you can check the working before you rely on it.
🎬 Audio & Video 13 tools
Audio and video tools trim clips, convert between formats, compress a file that is too large to send, and pull the sound out of a video. Short edits run in your browser using the same media engine that plays video. Speech to text is the exception: that audio is processed on our server because recognition models are too heavy for a phone. Podcasters, students and anyone captioning a clip use these.
🧩 Puzzles 5 tools
Puzzle makers build printable word searches, crosswords, sudoku grids, cryptograms and mazes from your own word list. You choose grid size, difficulty and layout, then print the page or save a PDF with a separate answer key. Teachers, parents, activity coordinators in aged care, and people assembling puzzle books to sell are the regular users. Whatever you generate is yours to keep and use.
🍎 Teacher 12 tools
Teacher tools produce classroom material you can print the same morning: flashcards, bingo cards, handwriting practice sheets, name pickers, worksheet headers and award certificates. They are deliberately plain so they photocopy well, they need no login, and the words you type are not stored anywhere. Relief teachers, tutors, Sunday school volunteers and home educators tend to get the most out of them.
🚜 Business 12 tools
Business tools are aimed at one-person operations rather than corporations: measuring a block on a satellite map and pricing the job, working out material quantities, turning a spoken site note into a written quote, generating an invoice. They follow how a small trade or service business actually works, and they produce something you can print, email or hand straight to a customer.
🔳 QR Codes 3 tools
QR code tools create codes for a web address, a WiFi network or a contact card, with control over size, colour and error correction, and download them as PNG or SVG at print resolution. The code is drawn in your browser, so the address or the WiFi password you encode is never sent to us. Handy for cafe menus, signage, event tickets and business cards.
✨ Name Generators 4 tools
Name generators are for when you are stuck: business and brand names, band names, gamertags, stream handles, character names and usernames. They combine word lists and naming patterns rather than doing anything clever, which is exactly what makes them useful for brainstorming. Nothing is registered or reserved, so check the domain, the handle and the trademark register yourself before you commit.
💻 Developer 11 tools
Developer tools are the small utilities you otherwise keep a scratch tab open for: formatting and validating JSON, encoding and decoding Base64 and URLs, hashing text, generating UUIDs, comparing two blocks of text, testing regular expressions and converting between data formats. All of it is processed locally, which matters a great deal when the thing you just pasted is an API token or a customer record.
🧰 Everyday 15 tools
Everyday tools are general purpose helpers: strong password generation, word and character counts, random pickers and dice, stopwatches and timers, case conversion, and quick text cleanup. None of them need an account and most finish in one click. They are here because these are the jobs people look up dozens of times a week and should not have to install anything to do.
🎉 Copy & Paste 7 tools
Copy and paste tools give you text that keeps its look when you paste it somewhere else: unicode fonts, bubble and strikethrough styles, symbols, emoji and text art. You type on one side and copy the version you want from the other. Popular with people writing social media bios, stream overlays, forum signatures and headings for fields that do not allow formatting.
🔮 Mystic 14 tools
Mystic tools cover astrology, numerology, tarot and related traditions: birth charts, angel numbers, life path numbers, compatibility readings, card draws and sound tools. They follow the traditional systems faithfully and are offered for interest and entertainment, not as prediction or advice. Charts are calculated in your browser from the birth details you type, and those details are not stored or sent to us.
