About
Small tools, done properly.
Vyze Apps is a collection of 134 fast, free utility tools built by Vivid Technologies. Most tools online for these jobs are slow, cluttered with ads, or hide the answer behind a form. We build the opposite: a single clear input, an instant result, and the reasoning to back it up.
Instant over intrusive
Every tool gives an answer without an email wall or account. Speed is the product.
Accurate, not approximate
Real formulas and maintained data behind each tool — results worth trusting and citing.
Open to everyone
Ad-supported so the tools stay free. No paywalls, no trials, no gated features.
Your files never leave your device
Every PDF, image, video, and audio tool here runs entirely inside your browser. There is no upload step, no server that holds your file for a retention period, and nothing to delete afterwards — the conversion happens on your own machine using WebAssembly builds of ffmpeg and pdf-lib that the page downloads once.
That is a deliberate architectural constraint, not a marketing line. It is also the reason some tools have a file-size cap: everything runs on a single browser thread, so we refuse a file we cannot process rather than freezing your tab. We think that is the right trade for contracts, medical scans, and anything else you would rather not hand to a stranger’s server.
What we build
- Finance & Tax — 25 tools. Mortgages, paychecks, taxes, loans and savings — every calculator here gives you the number instantly, shows the formula behind it, and never asks for an email.
- Document Tools — 23 tools. A complete PDF toolkit that runs entirely inside your browser. Your documents are never uploaded to a server, which makes these safe for contracts, records and anything confidential.
- Home & Garden — 18 tools. Work out how much material a project needs — and what it will cost — before you go to the store. Each calculator shows the waste factor and the assumptions it used.
- Image Tools — 18 tools. Convert, resize and edit images without uploading them anywhere. Every tool here uses your browser's own image engine, so your photos never leave your device.
- Video Tools — 12 tools. Compress, trim and convert video without uploading a single byte. These tools run ffmpeg inside your browser, so even large personal videos stay entirely on your machine.
- Developer Tools — 9 tools. Small utilities for developers, no signup required.
- Audio Tools — 7 tools. Pull audio out of video or convert between audio formats, all inside your browser. Nothing is uploaded, and once the converter has loaded it even works offline.
- Lifestyle & Events — 4 tools. Planning and hobby maths, without the signup.
- Business Tools — 3 tools. Small, sharp tools for running a business — invoicing, fees and campaign maths — that give you the answer immediately instead of pitching you a subscription.
- Education — 3 tools. Grade and GPA maths, done instantly.
- Automotive — 3 tools. Tire sizing and running-cost maths for your vehicle.
- Health — 3 tools. Health estimates with their assumptions stated plainly.
How we make money
Ads, and only ads. There is no paid tier, no “pro” export, no trial that expires, and no feature held back to make you sign up. We would rather show you an ad than take your email address, and we do not sell or share what you type into a calculator — in most cases it never reaches us at all.
