Frequently Asked Questions
Does this permanently change my original file?+
No. The effect is applied to a copy rendered in your browser. Your original image on disk is never touched — you download a new file with the effect applied.
Can I adjust the intensity before downloading?+
Yes. Every slider updates the preview in real time, so you can fine-tune the effect before exporting the final image.
What format is the downloaded file?+
PNG, to preserve full quality and, where relevant, transparency.
