Epsylon Tools
70+ free tools that never touch your files. 100% browser.
Epsylon Tools is a free suite of 70+ online tools built for freelancers, small businesses and everyday users. PDF (merge, split, compress, rotate, watermark), image editing (compress, resize, convert, background removal), file converters (HEIC, WebP, audio), finance calculators (VAT, invoicing, salary simulator), and developer utilities — all running 100% in your browser. No file ever leaves your device, no account required, no usage limits.
Hey everyone! 👋
I'm Florian, indie dev from France. I built Epsylon Tools out of frustration: every time I needed to compress a PDF or convert a HEIC photo, I had to upload my files to someone else's server. For contracts, invoices, and personal documents, that never felt right.
So I built my own tools — all running 100% in the browser using open-source libraries like pdf-lib, Tesseract.js and FFmpeg.wasm. No upload, no account, no limits.
What started as a handful of internal utilities grew into 70+ tools: PDF suite, image editing, file converters, finance calculators for French SMBs, and even 24 browser games for the fun of it 🎮
The whole thing is free and funded by my main project, Epsylon — an ERP for repair shops and small retailers in France.
Would love your feedback! What tools would you like to see added? And curious — do you care about local processing, or is uploading to a server fine for you?
Have you seen any problems ?
