FAQ
Do you upload my images?+
No. Adjustments run entirely in your browser using the Canvas API. Your files never leave your device.
Can I reset the sliders?+
Yes. Use Reset sliders to return brightness, contrast, and saturation to zero.
Will this compress my photo?+
Re-encoding can change file size slightly. Use PNG for lossless-looking exports, or lower quality on JPG/WebP to shrink the file.
Is PrivyTool free?+
Yes. Basic image tools are free with no account required.
