Digital tools built to respect your privacy and time
CoreBasics was born to replace slow, intrusive converters with fast, free, client-side web utilities where your files never leave your device.
Why we built CoreBasics
Every day, millions of people need to perform simple tasks: compress an image for an email, sign or merge a PDF document, create an avatar for Discord, or extract a color palette. However, the modern web has made these everyday actions frustrating.
Most online converters force users to upload sensitive contracts and personal photos to unknown cloud servers, wait in artificial queues, install suspicious desktop software, or hit aggressive paywalls after processing just two files.
We believed there was a better way: harness the computing power of modern browsers to run everything locally, safely, and instantaneously.
Zero-Upload Engineering: Client-Side First
CoreBasics is built on modern web standards including WebAssembly (Wasm), Web Workers, HTML5 Canvas, and client-side machine learning via ONNX Runtime Web. When you compress a 50 MB PDF or remove the background of an ultra-high-resolution photo, the entire workload is executed by your own computer or smartphone CPU and GPU.
Our Core Principles
Privacy First
We do not store your files because we cannot see them. There are no databases with your sensitive documents.
Speed & Simplicity
No registrations, no recaptchas, no countdowns. Open the tool, drop your file, and get your result in seconds.
Transparency
CoreBasics is sustained through non-intrusive advertising (Google AdSense) to keep all tools free for everyone.
Who is behind CoreBasics?
CoreBasics is maintained by an independent group of software engineers, designers, and web enthusiasts dedicated to building fast, respectful software. We continuously improve our algorithms, add new format converters, and monitor web standards to ensure maximum compatibility across browsers.
