A practical filter workflow
Start with brightness and contrast, then adjust saturation. Extreme settings can remove highlight or shadow detail, so compare the preview at normal zoom. Use grayscale last when you need a monochrome result.
คำถามที่พบบ่อย
Do adjustments reduce the image dimensions?
No. The output canvas uses the original image width and height.
Can I reset the filters?
Yes. Reset returns brightness, contrast, and saturation to 100 percent and grayscale to zero.
รูปภาพของฉันถูกอัปโหลดหรือไม่?
