Smaller File Sizes

WebP and AVIF typically deliver 25–50% smaller files than JPEG at the same visual quality.

Why convert PNG to WebP?

PNG files are lossless and often huge — screenshots, logos and UI graphics saved as PNG can be several megabytes. WebP supports the same full transparency (alpha channel) at a fraction of the size: lossy WebP is typically 60–80% smaller than the source PNG. Convert below without uploading anything; transparent areas stay transparent.

Frequently Asked Questions

Does WebP keep PNG transparency?
Yes. WebP has full alpha-channel support, so transparent and semi-transparent pixels in your PNG are preserved exactly in the converted WebP file.
How much smaller is WebP than PNG?
For typical screenshots and graphics, lossy WebP at 80% quality is 60–80% smaller than the original PNG. Even lossless WebP is usually about 25% smaller.
Should I use WebP instead of PNG on my website?
For almost all web use cases, yes — you get the same visual result with far smaller files. Keep PNG only when you need a universally editable lossless master file.
