Desktop Image StudioFree

Batch-process images into every size & format at once.

Minimage is a fast, tiny desktop studio that resizes, converts, optimizes, annotates and compares images in bulk — building a full matrix of sizes × formats from any files or folders. Native Rust speed, ~8 MB, and everything stays on your machine.

How it works

One pass builds every combination

Choose your sizes once and your formats once. Minimage renders every image for every size × every format — a complete matrix of outputs from a single run.

3 sizes × 3 formats = 9 outputs per image, automatically. Add a target file-size budget and Minimage auto-tunes quality so each one lands under your limit.

Capabilities

Everything you need to ship images

A focused set of tools that cover the whole job — from intake to a clean, optimized export.

Batch matrix: sizes × formats

Pick any images or folders, define multiple sizes and multiple formats, and every image is rendered for every size × every format in one run.

8 output formats

WebP, AVIF, JPEG, PNG, GIF, TIFF, BMP and ICO — each with its own quality, lossless toggle, PNG optimization level, and AVIF/WebP effort.

Target file size

Set a KB budget per format and Minimage auto-tunes quality per image so each output lands at or under your limit.

Smart resize modes

Fit, Cover (center-crop), Pad, Stretch, single-dimension keep-aspect, or scale %. Optional upscaling. SVGs are rasterized crisply at every size.

Annotate & edit

Crop, rotate, flip, blur, draw and annotate before export. Apply batch-wide color adjustments, transparency flattening, and text or logo watermarks.

Metadata stripped

Outputs are re-encoded from raw pixels, so camera EXIF, GPS coordinates, and color profiles are always removed — smaller files, no location leaks.

Presets & templated names

Save a whole setup and reload it in one click. Name files with tokens like {name}_{width}x{height}.{ext}, using / to create sub-folders.

Tiny, native & offline

Built with Rust + Tauri, so the installer is ~8 MB instead of 80 MB+. All work happens on your machine — no cloud, no uploads, no account.

Formats

Reads what you have, writes what you need

  • WebP — lossy + lossless
  • AVIF — next-gen, tiny
  • JPEG — universal
  • PNG — oxipng optimized
  • GIF — animation frames
  • TIFF — archival
  • BMP — raw bitmap
  • ICO — app icons
  • SVG — rasterized in
Private by design

Your images stay yours

Minimage is a local-first desktop app. There's nowhere for your photos to go but the output folder you choose.

Runs fully offline

Every operation happens locally in native Rust. No cloud, no uploads, no account — your images never leave your machine.

Metadata stripped on export

Outputs are re-encoded from raw pixels, so EXIF, GPS coordinates and color profiles are removed automatically. Smaller files, no location leaks.

Tiny native footprint

Built on Rust + Tauri instead of Electron, the installer is ~8–12 MB — no bundled browser, no Node runtime, no node_modules in the output.

Zero telemetry

Minimage collects no analytics and makes no network requests to do its work. What you process is your business alone.

Questions

Frequently asked

What does Minimage do?

Minimage is a batch image studio. You select images or whole folders, define one or more target sizes and one or more output formats, and it produces every combination at once — resizing, converting, optimizing, and optionally annotating or watermarking along the way.

Is Minimage free?

Yes. Minimage is completely free and open source under the MIT license, for both personal and commercial use.

Does Minimage upload my images anywhere?

No. Minimage is a desktop app that processes everything locally on your own machine. Your images never leave your computer, there is no account, and it works fully offline.

Which platforms are supported?

Windows, macOS, and Linux. Grab the installer for your OS from the GitHub Releases page — .exe/.msi for Windows, .dmg for macOS, and .AppImage/.deb/.rpm for Linux.

Which formats can it export?

WebP, AVIF, JPEG, PNG, GIF, TIFF, BMP, and ICO. Each format has its own quality, lossless toggle, optimization level, and effort settings. You can also set a target file size in KB and Minimage will auto-tune quality to hit it.

Will my photos' location data be removed?

Yes. Outputs are re-encoded from raw pixels, so EXIF, GPS coordinates, and color profiles are stripped automatically. That means smaller files and no accidental location leaks when you share images.

Resize, convert and optimize in bulk — for free.
