Frequently Asked Questions
Does converting WebP to PNG preserve transparent backgrounds?
Yes! Our converter exports lossless 32-bit RGBA PNG files, preserving full alpha transparency layers without adding white borders or black background artifacts.
Can I remove a solid background color from a WebP image?
Yes! You can toggle the Color-Key Alpha Eraser, choose a background color (like pure white or green screen), and adjust the tolerance slider to turn that background into transparent alpha pixels.
What does the Auto-Trim Empty Margins feature do?
Auto-Trim scans the alpha channel of your image and automatically crops away useless transparent padding around logos, signatures, and stickers to tightly fit the graphic.
Can I batch convert multiple WebP files and download them as a ZIP?
Yes! You can upload multiple WebP files at once. Our batch processor converts them in parallel inside your browser RAM and packages them into a clean ZIP archive.
Does the output PNG contain verified 300 DPI print tags?
Yes. Our binary encoder injects verified 300 DPI pHYs chunks directly into the PNG data stream, ensuring professional print readiness.
