Designed by a film photographer, for film photographers

Trevni focuses on faithful conversion, not gimmicks. Giving you clean, natural results while staying out of the way of your creative process.

Fixes to RAW support:
Trevni now supports RAW files from cameras, DNG, and ProRAW from iPhone. Your negative is processed at full resolution, preserving much more detail for conversion and editing.

Full-resolution export:
Save your finished positive as JPEG, HEIC, or TIFF. TIFF keeps every pixel for further editing; JPEG and HEIC are better for sharing.

Your photo’s details come with it:
Camera, lens, exposure settings, date, and location carry across to the saved image, so an inverted frame stays as easy to find in your library as the original.

Smoother to use:
Sampling the film base and moving the adjustment sliders are noticeably more responsive, especially on large files.
