What is WebP?
WebP is an image format created by Google for the web. It supports lossy and lossless compression, transparency and animation, and usually makes files 25–35 % smaller than JPG or PNG at the same visual quality. WebP is best for fast-loading websites, online shops and blogs. Older software, some print services, Windows Photo Viewer in older versions, many desktop design tools and some upload forms still refuse WebP files.
What is PNG?
PNG is a lossless raster format: every pixel is kept exactly, and it supports full transparency (alpha channel). It is the standard for logos, screenshots, icons and graphics with text or sharp edges. PNG is best for logos, screenshots, graphics with text and anything that needs a transparent background.
When should you convert WebP to PNG?
- You saved an image from a website and it came out as .webp, but your editor, printer or upload form only accepts PNG.
- You need a lossless copy to edit: PNG keeps every pixel, so repeated editing adds no compression artefacts.
- The image has a transparent background (logo, sticker, product cut-out) and must stay transparent.
Tips for the best result
WebP transparency is kept exactly in the PNG. If the WebP was lossy, the PNG preserves it as it is — converting never restores detail that was already compressed away, but it stops any further loss.
