Why choose Loconva?

Local-first privacy

Private by design

Files are processed locally in your browser and are not uploaded to Loconva's servers.

Your source files stay on your device for browser conversions, reducing unnecessary exposure and transfer time.

A shorter path to the result

Fast, direct processing

Avoid upload queues and unnecessary transfers. Performance depends on the file and your device.

Conversion starts directly on the device, without waiting for a remote upload queue.

One focused workspace

Broad format support

Convert images, documents, audio, video, structured data, archives, fonts, and ebooks.

Move between common professional and everyday formats from one consistent interface.

Work wherever you are

Designed for every device

Use the responsive interface on desktop, tablet, or mobile, with optional offline access after setup.

The same clear workflow adapts across screen sizes and can remain available when your connection is limited.
