Frequently Asked Questions
PNG and WebP formats support full transparency (alpha channel), making them ideal for logos and watermarks. GIF supports binary transparency (fully transparent or opaque). JPG doesn't support transparency and will have a white or colored background.
Blending modes determine how overlay pixels combine with base image pixels. Normal mode places the overlay on top, Multiply darkens by multiplying colors, Screen lightens by inverting and multiplying, and Overlay combines Multiply and Screen for contrast.
Yes, you can overlay multiple images by applying them sequentially. Each overlay becomes part of the base image for the next overlay. This allows complex compositions with logos, watermarks, and decorative elements.
Use high-resolution images for both base and overlay. Match the resolution of your overlay to the base image scale. Save in PNG or WebP format to preserve transparency and quality. Avoid repeated saves in lossy formats.
For watermarks, 15-30% opacity typically works best - visible enough to protect your image but not distracting from the content. For logos and branding, 80-100% opacity is common. Adjust based on your image colors and purpose.
