How it works
1
Upload
Drop your PNG image into the box above — or click to browse. It is read locally; nothing is uploaded.
2
Convert
WebP is pre-selected as the output format. Adjust the quality slider if shown, then hit Convert & download.
3
Download
Save your new WebP file with the correct extension. Repeat for as many images as you like — no limits.
The best of both worlds
PNG to WebP is the rare conversion with no real downside for web use. You keep what makes PNG great — lossless-ish quality and full transparency — while getting files up to 80% smaller thanks to WebP's modern codec.
Logos, UI graphics, screenshots with transparency and illustrations all thrive as WebP. It is the single most impactful image optimization most websites have not done yet — and it takes one click per file.
Tips
- Transparency is fully preserved. Unlike JPG conversion, WebP keeps the alpha channel — transparent PNGs stay transparent.
- Expect dramatic savings. PNGs routinely shrink 60–80% as WebP with no visible change — the biggest win of any conversion on this site.
- Quality slider matters less here. WebP handles graphics beautifully even at 80–85%; reserve 90%+ for photographic PNGs.
- Still need PNG somewhere? Keep the originals — a few legacy systems and print workflows still want PNG.
