Rimatte by OpenFilmmaker
Your photos.
Your folders.
Your workflow.
Rimatte is a lightweight, local-first photo utility built for photographers who want to browse, organize, compare, frame, export, and present photos without importing them into a proprietary catalog.
Free to use · No account required · Your photos stay in their normal folders
Practical photo tools
Enough to get the work done. Not another Lightroom.
Rimatte stays focused on the everyday things photographers do around their images, without trying to become a full RAW editor or lock you into a catalog.
Organize
Favorites and file tools
Favorite photos, create groups, rename, copy, move, reveal, and send files to your operating system’s Trash or Recycle Bin.
Compare
Inspect 2–4 photos together
Compare selections side by side with synchronized zoom and pan when you need to choose the strongest frame.
Present
Borders, text, and watermarks
Add clean borders, captions, signatures, or copyright text and export finished copies without altering your originals.
Slideshow
Turn selections into video
Build a reorderable slideshow and export HD or Full HD MP4 video with optional transitions and background treatments.
Export
Fast, high-quality copies
Create JPEG exports at practical output sizes with quality control, safe filenames, and no automatic upscaling.
Local-first by design
Your photo library is already where it belongs.
Rimatte works with the files and folders you already have. There is no required import step, cloud library, or proprietary catalog between you and your photos.
No account requiredOpen Rimatte and work locally. Browsing and organizing do not require a sign-in.
No catalog lock-inYour folders remain ordinary folders and your images remain ordinary image files.
Non-destructive outputsPresentation and export features create new files instead of silently changing originals.
Built for photographersRimatte focuses on browsing, selection, organization, presentation, and export—not full photo development.
