Frequently Asked Questions

What filters are available?
Black & White (Grayscale), Sepia (vintage warm tone), and Invert (negative). You can also adjust brightness and contrast independently.
Can I combine multiple filters?
Yes! You can apply a color filter (B&W, Sepia, Invert) and then adjust brightness and contrast on top of it for the exact look you need.
Does this work for document scans?
Yes — converting scanned documents to black & white with increased contrast makes text clearer and more readable, and also reduces file size.
Is the preview real-time?
The preview updates instantly using CSS filters for fast visual feedback. The final download applies the filter at full resolution using pixel manipulation.
Will the output format change?
No. The output maintains the same format as your input (JPEG stays JPEG, PNG stays PNG).
