PNG and WEBP can both support transparency, but they differ in compression and typical file size. Neither is always better; the right choice depends on the image and where it will be used.
WEBP often creates smaller photographs for the web, while PNG is predictable for simple graphics and lossless preservation.
Start with these choices
A strong option when smaller web images and faster loading matter.
Useful for crisp lines, text, limited colors, and transparent assets.
PNG or JPG may be safer when files must open in very old software.
How to do it in your browser
- 1
Decide whether the source is a photograph or a logo, icon, or screenshot.
- 2
Prefer WEBP for web photos and PNG for lossless graphics.
- 3
Check file size, transparency, and edge quality before saving.
When PNG works best
PNG uses lossless compression and preserves transparent areas. It is commonly used for logos, icons, screenshots, and graphics containing small text.
- Transparent logos and icons
- Screenshots with text
- Graphics where exact pixels and colors matter
When WEBP works best
WEBP can make photographs and web content much smaller than PNG. It supports lossy, lossless, and transparent images, but the receiving software must support the format.
- Website hero and product images
- Blog photographs
- Pages where mobile data and loading speed matter
What changes during conversion
A lossy WEBP can reduce a PNG dramatically, but tiny text and sharp lines may soften. Saving a photograph as PNG may preserve pixels while producing an unnecessarily large file.
Frequently asked questions
Does WEBP support transparency?
Yes. WEBP supports transparent areas, but confirm that the editor or service receiving the file handles WEBP transparency correctly.
Is WEBP always smaller than PNG?
It is often smaller for photographs. A tiny, simple graphic may show little improvement or can even become larger with some settings.
Does converting WEBP back to PNG restore the original?
No. Detail removed by lossy WEBP compression cannot be restored by changing the file to PNG.
