Frequently Asked Questions
Does this tool support RAW files?
No, only common web raster formats: JPG, PNG, WebP, etc. RAW files must be converted first.
Will my image quality degrade?
Adjustments are applied pixel-per-pixel, but to keep the sliders smooth, the preview canvas may be limited to 2048×2048 px. The downloaded image retains the final slider values applied to the full-size canvas.
Can I adjust each parameter separately?
Yes, all three sliders work independently or together, and you can reset them to zero at any time.
