Rimatte application showing the main photo browsing workspace

Work directly with photo folders on your PC, with browsing, metadata, favorites, comparison, and finishing tools close at hand.

Keep the small photography jobs small.

Rimatte is not trying to replace your RAW editor. It handles the practical work around it: finding photographs, choosing between frames, preparing presentations, and exporting finished copies.

Four core workflows

From folder to finished photograph.

Rimatte brings its major capabilities together around the parts of a photographer's workflow where a full editor or catalog can feel like more than you need.

Rimatte Favorites view with photographs organized for quick access

Browse & organize

Work with the folders you already have

Navigate folders and subfolders, search by filename, inspect metadata, zoom and pan, view full screen, and keep important photographs close with persistent Favorites and Favorite Groups.

Compare

Choose between similar frames

Compare 2–4 photographs side by side with optional synchronized zoom and pan so you can inspect details without moving into a heavyweight catalog workflow.

Finish

Rimatte Photo

Rotate or flip, add borders and Soft Bottom shadow, place text or watermarks, add transparent PNG logos, and save reusable Rimatte Presets for presentation settings you use again.

Rimatte Contact Sheet creator with a grid of photographs

Present & export

Turn selections into something useful

Create JPEG or PDF contact sheets, build and save slideshow projects, export MP4 or animated GIF slideshows, or make high-quality resized JPEG copies with Quick Export.

Contact sheets

Flexible columns, filenames, sequence numbers, headers, and optional EXIF captions.

Slideshows

Tag and reorder photos, save projects, and export 1080p or 720p H.264 MP4 video or animated GIFs.

Photo utilities

Duplicate detection, burst grouping, EXIF filtering, conversion, privacy/social exports, metadata copy, batch rename, and cache tools.

Your files stay familiar

Your folders. Your photographs.

Rimatte works directly with photographs already stored on your computer. Normal browsing and organizing do not require an account or cloud photo library. Thumbnail cache and application state stay local while full-size photographs remain in their existing folders.

Presentation exports create new output files. Explicit file-management actions such as rename, move, and Recycle Bin only happen when you choose them.

Focused by design

Not another RAW editor.

Rimatte does not currently decode RAW photographs and is not a full image-editing suite. Use your preferred editor for RAW development, masks, advanced color work, and other heavyweight tasks.

Rimatte is for the smaller photography jobs that should not require opening all of that.

Why Rimatte?

It started with borders.

I originally built Rimatte because I wanted a quick way to add clean borders to my own photographs without opening a full photo editor every time. That grew into a focused set of tools for the small but recurring jobs around a photography workflow.

The name combines rim and matte, two ideas tied to presenting and framing a photograph.

Building Rimatte

The product is also an ongoing software project.

Alongside building the photography workflows, I'm documenting how Rimatte is designed and developed: product decisions, software architecture, documentation practices, and where AI-assisted development helps or falls short.

Those notes are the story behind the product, not the product itself. Rimatte remains a photography application first.

Slideshow export

MP4 slideshow export uses FFmpeg. Rimatte keeps that optional so the base installer stays lightweight.

Frequently asked questions

The short version: Rimatte is a Windows photography utility that works with ordinary files and folders.

What is Rimatte?

Rimatte is a lightweight Windows photo workflow for browsing folders, organizing favorites, comparing photographs, creating contact sheets and slideshows, finishing images for presentation, and exporting copies without requiring a proprietary catalog.

What does “Rimatte” mean?

The name combines rim and matte, two ideas tied to framing and presenting a photograph. Rimatte Photo is the workflow for transforms, borders, shadows, text, watermarks, logos, and reusable presentation presets.

Yes. Rimatte is currently free to download and use.

Do I need to upload or import my photos?

No. Rimatte works directly with ordinary folders on your PC and does not require a proprietary catalog or cloud photo library.

Does Rimatte modify my original photographs?

Normal viewing, organizing, comparison, and exports do not silently modify originals. Rimatte Photo exports create new copies. The explicit Apply to Original command can save supported rotate/flip transforms to JPEG or PNG originals after confirmation, and file-management commands such as rename or move run only when you choose them.

Does Rimatte support RAW files?

Not in the current release. Rimatte currently focuses on JPEG, PNG, BMP, WebP, and TIFF workflows.

Is Rimatte a Lightroom or Photoshop replacement?

No. Rimatte intentionally focuses on lightweight viewing, organization, presentation, and export tasks rather than RAW development or advanced image editing.
