PNG vs WebP: Which Is Better?
PNG is a strong choice for lossless graphics and transparency. WebP can often reduce file weight while supporting both lossy and lossless modes, including transparency.
What to do
For web delivery, compare the actual WebP result against the PNG and keep the smaller file only if the visual result and compatibility are acceptable. The simplest next step is to PNG to WebP. If the issue is actually about image size checker, see Image Size Checker as well.
Why this happens
Image problems often come from three separate variables: pixel dimensions, encoded file size and file format. Changing one does not automatically solve the others. A very large photo may need resizing even when its format is already JPG; a transparent graphic may need PNG or WebP even when the file size is acceptable; and an upload limit may be measured in megabytes rather than pixels.
Before editing, check the requirements of the place where the image will be used. That gives you a concrete target and reduces unnecessary quality loss. When possible, keep the original file and create a delivery copy for the specific destination.
Common questions
Does WebP support transparent images?
Yes. WebP supports transparency.
Is WebP always smaller than PNG?
No. Results depend on the image and encoding settings.
Should I replace every PNG with WebP?
No. Check the destination requirements and whether the conversion actually provides a useful reduction.
