Quality boundary
Choose a smaller lossy WebP or true lossless WebP with exact transparent RGB values.
How this file is processed
The file stays on this device during processing. Review the result before consequential use.
Choose a web image format with clear tradeoffs
Convert PNG to WebP while protecting transparency and sharp graphics.
WebP can reduce the delivery weight of PNG graphics and photographs while retaining transparency. Choose lossless mode when exact transparent RGB values and crisp interface artwork matter.
Identify why the source is PNG
Logos, icons, screenshots, diagrams, and product cutouts often use PNG for transparency or sharp edges. Preserve those requirements in lossless WebP. Lossy conversion may suit photographic content when a smaller file matters more than exact pixels.
Inspect transparency against two backgrounds
Preview the result on both light and dark backgrounds. Check soft shadows, anti-aliased edges, semi-transparent pixels, and color fringes around cutouts instead of reviewing only the opaque center of the image.
Measure savings before replacing the PNG
Compare file size, dimensions, transparency, text sharpness, and browser rendering. Keep the PNG as the editable or compatibility source and deploy WebP only when the destination accepts it and the reduction is worthwhile.
