FAQ
Is the transparent background kept?
Yes. WebP natively supports alpha transparency — transparent areas stay transparent.
Is PNG to WebP lossy or lossless?
This tool uses adjustable lossy encoding by default; at 85+ it is visually lossless. For strict pixel-perfect needs, push the slider to maximum.
Will text in screenshots get blurry?
At quality 85–95 screen text stays sharp; for dense text screenshots use 90 or higher.
About this PNG to WebP
PNG is the go-to format for screenshots, icons and transparent artwork, but lossless compression comes at a cost: big files. WebP also supports an alpha channel while typically weighing just 30%–50% of the PNG at near-identical quality — the highest-value optimization for web icons, buttons and logos. Conversion happens entirely in your browser; originals are never uploaded.
