Privately. On your computer.
Batch-compress images locally on Mac, Windows, or Linux. No uploads, no internet required, no subscription.
Built for private production work
Compression that respects your files and your time.
Private by design
Your images and videos are processed on your computer, so client files do not need to pass through a third-party upload queue.
Built for batch work
The desktop workflow is made for repeated compression tasks: folders, large sets, and production assets that browser tools make tedious.
Simple lifetime pricing
Pay once for Pro and keep using it without monthly renewals, usage meters, or surprise subscription lock-in.
Online tools are the bottleneck in your workflow.
Waiting for uploads is a waste of time. Your computer has the power — use it to optimize images instantly.
Slow uploads and data privacy risks
Don't put your client's unreleased assets on a 3rd party server.
Queue times and API fatigue
Stop managing API keys or waiting for external servers to finish.
Arbitrary limitations and subscriptions

Frequently Asked Questions
Answers to the most common questions about our tool
Is it really private?
Yes. FastCompressor performs all operations on your local CPU/GPU. It processes everything locally on your device. Your images never leave your machine.
Why use this over online tools?
Online tools are slow, limit file sizes, and pose a privacy risk. FastCompressor is built for bulk workflows—compressing hundreds or thousands of assets instantly without waiting for any server.
What happens after the free limit?
You can continue using the app for free! You'll just be limited to 20 images per session. To unlock unlimited bulk processing a one-time upgrade is available.
Does it support batch processing?
Yes! You can drag and drop multiple images or entire folders for simultaneous processing, saving you time and effort.
How do I compress a TIFF file without losing quality?
FastCompressor uses lossless LZW and Zip-based compression to reduce TIFF file size without any data loss. Simply open the app or use the online TIFF compressor, drop your .tif files, and download the optimized TIFF — the format stays the same and every pixel is preserved.
Does FastCompressor work offline on Mac, Windows, and Linux?
Yes! FastCompressor is a fully offline image compressor. Download the free desktop app for macOS, Windows 10/11, or Linux. All compression happens locally on your machine — no internet connection required and your files never leave your device.
