常见问题解答

Will applying a filter permanently change my original file?
No. DCPIXEL processes a copy of your image in the browser. Your original file on disk remains completely unchanged. You download a new file with the effect applied.
Can I adjust the intensity of the effect?
Yes. Sliders for brightness and contrast let you fine-tune the effect. Changes preview in real time so you can find the perfect look before downloading.
Can I combine multiple effects?
Currently each tool applies one primary effect. For multiple effects, download the result from the first tool and use it as input for the next one.
What image formats are supported for effects?
JPG, PNG, and WebP are fully supported. The output is saved in the same format as your uploaded image.
