About SoloStep

SoloStep is 17 image and PDF tools that run entirely in your browser, built and maintained by Vansh Sharma.

Why it exists

Converting a file should not require handing it to a stranger. Most free converters upload your photo, your ID scan or your bank statement to a server you know nothing about, then show you an advert while you wait. Browsers have been able to do this work locally for years. SoloStep just does it that way.

What makes it different

Three things. Nothing is uploaded — you can verify that in your own network tab. The exact output size is always shown, and it matches the file you download. And every tool states its real limits: no tool can compress losslessly to an arbitrary target, animation cannot survive a conversion to JPG, and a PDF under 100KB with five pages will look rough. Saying so is more useful than pretending otherwise.

How it is built

The site is static HTML, generated at build time and served from a CDN. The conversion engines are JavaScript and WebAssembly that load only once you have chosen a file, so the pages stay fast on a mid-range phone. There is no backend, no database and no account system — by design, not as a limitation.

What is coming

OCR — pulling text out of an image — is the obvious next step, and it will ship once its accuracy can be described honestly rather than optimistically. Word and Excel rendering is harder to do well in a browser, and will not ship until it either works properly or can be explained clearly.
