PicTrim is a high-performance batch image processing tool for resizing, compressing, rotating, and converting images.

Features

• Mix image files and folders as input, or drag them directly into the app.
• Batch resize by longest side, bounding box, fixed crop, width, or height.
• Export JPG, PNG, and WebP, or keep the original format.
• Configure quality, rotation, concurrency, upscaling, existing-file handling, and non-image file handling.
• Preserve folder structure while showing live progress, stats, logs, and failures.

Performance

• PicTrim is built to be an extremely fast batch image processing tool.
• The core uses Rust and libvips for high throughput and low memory usage.
• A streaming task queue plus multithreaded processing makes very large image sets practical.
• Existing output files can be skipped, which is useful for repeated or incremental runs.

Usage

1. Add image files or folders.
2. Choose an output folder.
3. Set the size, format, quality, and batch options.
4. Click "Start".

Platform Support

• macOS
• Windows 10 / Windows 11 64-bit

Current release builds target macOS and Windows x64. Linux packages are not provided yet.

Development

npm install
npm run dev

Check the frontend build:

npm run build

Check the Rust side:

cd src-tauri
cargo check

Building or linking the Rust binary requires libvips to be installed locally.

macOS:

brew install vips

On Windows, use the official prebuilt libvips package and set VIPS_DIR to the extracted folder:

$env:VIPS_DIR = "C:\path\to\vips-dev-8.x"
$env:Path = "$env:VIPS_DIR\bin;$env:Path"

You can also refer to the official libvips installation guide.

Build

npm install
npm run tauri:build
npm run release:package

After the build finishes, release/PicTrim/ contains the portable build. Windows builds also create an NSIS installer and copy it into release/. npm run release:package generates the portable zip and SHA256SUMS.txt for GitHub Releases.

Release Notes

Current GitHub Releases provide unsigned binaries. macOS or Windows may show a security warning on first launch. Download from the project Releases page and verify file integrity with the bundled SHA256SUMS.txt.

See docs/release.md for the detailed release workflow.
