No uploads. It all happens on your device.
Most online converters upload your file to a server, process it there, and send it back. Vertly does none of that — the conversion runs entirely inside your own browser.
- 1
You pick a conversion
Choose from 29 converters — HEIC to JPG, WebP to PNG, PNG to PDF and more. Each one is a dedicated page tuned for that exact format.

Your browser reads the file
When you drop a file it's loaded straight into your browser's memory. HEIC is decoded with a small WebAssembly module; everything else uses the built-in canvas engine.

It re-encodes locally
The image is drawn to an off-screen canvas and re-encoded to your chosen format — JPG, PNG, WebP, or assembled into a PDF. No network request is ever made.

You download the result
The converted file is handed back as a download. It only ever existed on your device.
Why do it in the browser?
Privacy
Sensitive photos, IDs, screenshots — none of it is transmitted anywhere.
Speed
No upload/download round-trip. Conversion starts the instant you drop a file.
No limits
There's no server bill to pay, so there's no cap and no watermark.
