mrar

mrar is a small CLI tool that removes metadata from images and writes cleaned copies to an output folder.

It is useful for stripping EXIF data such as GPS coordinates, camera details, and other embedded metadata before sharing images.

Download

Windows

Download mrar-windows-x86_64.exe from the Releases page.

Then run it from PowerShell or Command Prompt:

mrar-windows-x86_64.exe F:\inputs\mar-inputs\apr

Example output:

Found 110 image(s) → output: F:\inputs\mar-inputs\apr\output
manifest written → F:\inputs\mar-inputs\apr\output\manifest.json
Done. 110/110 processed. 2858680 bytes stripped across all images.

Build from source

If you have Rust installed, you can build it yourself:

git clone https://github.com/darksolitaire9-hub/mrar.git
cd mrar
cargo build --release

The binary will be created at:

target/release/mrar.exe

Rust is typically installed via rustup, which also installs Cargo.

Usage

Pass a directory containing supported images:

mrar-windows-x86_64.exe <input-folder>

mrar will:

• Find supported images in the input folder.
• Remove metadata from each image.
• Write cleaned files to an output subfolder.
• Write a manifest.json file with processing details.

Verify metadata removal

You can visually inspect metadata on Windows by right-clicking an image, opening Properties, and checking the Details tab; fields like camera model, GPS, and date taken should be empty or absent on processed files.

Notes

• Originals are not modified; processed files are written to output.
• This is a local/offline tool; images are processed on your machine.
