I built a free file converter where files never leave your device

Hey DEV community! 👋

I built Transfyle — a free online file converter with 23 tools for PDF, images & documents.

What makes it different?

✅ Files NEVER leave your device — everything runs in your browser
✅ No account or signup required
✅ No watermarks, no limits
✅ Works offline too

Tools available:

PDF: Merge, Split, Rotate, Watermark, Compress, PDF to JPG
Images: Convert, Resize, Crop, Grayscale, Flip
Documents: CSV to JSON, XLSX to CSV
Calculators: Age Calculator, Simple Calculator

Why I built this

I was frustrated that most file converter sites upload your files to their servers. iLovePDF, Smallpdf — they all store your files somewhere. I wanted something 100% private.

So I built Transfyle — everything runs locally in your browser. Your files never touch any server.
