Frequently Asked Questions
Does compressing reduce image quality?
It depends on the settings you choose. By adjusting the quality slider, you can find the perfect balance between a small file size and an image that still looks sharp. Slight compression is often unnoticeable.
What is the maximum file size I can compress?
Since the compression runs entirely on your device, there is no hard limit imposed by our servers. The actual limit depends on your browser's available memory, but typical high-resolution photos work perfectly.
Is this tool actually free?
Yes. Image Darkroom is 100% free with no hidden fees, no subscriptions, and no watermarks on your compressed images.
Do you store or upload my images?
No. Your images are never uploaded to our servers. All processing happens locally in your browser, ensuring complete privacy and security.
