About PNG (Portable Network Graphics)
PNG is a lossless format: every pixel is preserved exactly, and it supports full alpha transparency. That makes it the default for screenshots, logos, UI graphics and cut-outs — at the cost of larger files than JPG or WebP for photographs.
About WebP (WebP)
WebP is a modern web format that typically produces 25–35% smaller files than JPG or PNG at the same visual quality, and it supports transparency. Every modern browser reads it; some older desktop apps still don't.
Frequently asked questions
Does WebP keep transparency?
Yes — unlike JPG, WebP has a full alpha channel, so transparent PNGs stay transparent after conversion.
How much smaller will the file be?
Typically 25–35% smaller than an equivalent PNG, often more for screenshots and graphics with large flat areas.
Are my files uploaded anywhere?
No. The whole conversion runs in your browser — your PNG files never leave your device, and there's nothing for a server to store or leak.
Is it free? Is there a watermark?
Yes, it's completely free — no signup, no watermark, no limits on how many PNG files you convert.
