Frequently Asked Questions
No. We render all adjustments at the full resolution of your original image. Your final export will be just as sharp as the original, but with perfectly optimized lighting and depth.
100% secure. Image Tool Bot uses advanced browser-side JavaScript, meaning your images stay on your local computer throughout the entire process for total, uncompromised privacy.
Make Your Colors Pop
A flat image lacks distinction between its light and dark areas. Boosting the contrast pushes the darks darker and the lights lighter, instantly giving your photo a vibrant, professional aesthetic.
100% Local Processing
Your images are highly sensitive. Unlike other websites, Image Tool Bot never uploads your photo to a cloud server. All editing and rendering happens directly in your device's browser using local memory.
