Local-first atelier

Files, recast in a new light.

Lumen is a conversion studio, not a dumping ground of format links. Drop a file, pick a destination, and the work happens on this device — with a command palette, live preview, and a navigation map you can actually scan.

Atlas

Navigate by craft, not clutter.

Seven rooms instead of a wall of duplicate links.

Popular routes

Start in the middle of a conversion.

Full library
01

Place the file

Drag anything onto Studio. Lumen reads the extension and mime type, then lights only the destinations that actually work locally.

02

Tune the recast

Quality, maximum edge, and a live preview for images. Swap source and target with one control instead of hunting another URL.

03

Keep the original

The new file downloads to you. Lumen does not store a copy, because the file never left the machine.

Privacy is the product

A converter that does not need your files.

Most online converters upload first and delete later. Lumen inverts that: raster work, PDF merge, and text extraction run in the browser. That is the uniqueness — not a greener banner.

Command palette

Press / or Ctrl K from any page to jump to JPG→PNG, Merge, or Guides. Navigation is a search, not a scavenger hunt.
