About SolveBox
SolveBox is a suite of 64 free web utilities built on a simple rule: your data should stay on your device.
Why We Built SolveBox
Every day, millions of people search for simple tools: compressing a PDF, removing an image background, formatting a JSON payload, or calculating loan EMIs. Unfortunately, most traditional online tools upload your confidential documents, personal photos, and sensitive data to remote cloud servers—often saving copies, displaying invasive ads, or demanding expensive subscriptions.
We believed there was a better way. Modern web browsers are extraordinarily capable computing platforms. By harnessing client-side technologies like WebAssembly (Wasm), WebGL/WebGPU, and HTML5 APIs, SolveBox runs complete computations directly within your local browser sandbox.
Absolute Privacy
Zero file uploads. Your documents, photos, code, and financial figures never leave your device.
Instant Speed
No upload queues, network bottlenecks, or server wait times. Operations process locally in milliseconds.
100% Free & Open
No paywalls, watermarks, mandatory accounts, or hidden usage limits. Free utility for everyone, everywhere.
Our Commitment
Whether you are a developer formatting an API response, a designer extracting a transparent product cutout, a student submitting a compressed resume, or an investor planning mutual fund goals, SolveBox is engineered to deliver immediate value within seconds.
We are constantly expanding our catalog with new, highly requested tools based on real user feedback.
