SuanTools Desktop

SuanTools Desktop is a lightweight, privacy-first file processing application for Windows that handles image compression, PDF manipulation, and file conversion without uploading anything to the cloud. Everything runs locally on your machine—your files never leave your device.

If you're currently using iLovePDF, SmallPDF, or TinyPNG in your browser, you know the friction: upload files, wait for processing on remote servers, hope nothing goes wrong during transmission. SuanTools Desktop eliminates that entirely. Process 100 images at once using all your CPU cores. Convert a 50-page PDF. Compress without losing quality. All offline. All on your hardware.

The speed difference is immediate. Built with Rust and the Tauri framework, SuanTools runs fast and uses minimal memory. Multi-core batch processing means you can queue hundreds of files and let the app work through them efficiently while you continue working.

SuanTools Desktop includes 25 tools organized into categories:

Image Tools: Batch compression (JPEG, PNG, WebP), format conversion, quality adjustment, metadata removal, watermark addition/removal, rotation, resizing, grayscale conversion, histogram analysis.

PDF Tools: Merge multiple PDFs, split by page, extract text, compress file size, add/remove passwords, rotate pages, remove metadata, convert to images, extract images.

Utility Tools: File hash calculation, batch renaming, duplicate file detection, color palette extraction, screenshot annotation.

Your financial statements. Your medical forms. Your client documents. None of it touches anyone's server. No browser cookies tracking your uploads. No data retention policies you have to trust. The files stay on your device, processed locally, and that's it.

Rust delivers real performance advantages. Compression happens 2-3x faster than web tools. Batch operations scale linearly with your CPU cores. The app uses 40-80MB of RAM even when processing large batches.

One-time purchase, perpetual license. No subscription. Regional pricing from $4.99 to $59.99 depending on your location. For web-based tools, SuanTools also offers a browser version with 30+ tools at suantanamo.com with the same privacy principle: client-side processing, nothing uploads.
