Convert PNG to WebP

PNG is a lossless format optimised for screenshots, logos and graphics with sharp edges or transparency. Its file size, however, can be punishing — a flat illustration that is 600 KB as PNG is often under 100 KB as lossless WebP and under 50 KB as lossy WebP, with no visible difference. Tiny Pixel Kit re-encodes your PNG to WebP in the browser. The alpha channel (transparency) is preserved automatically. For UI graphics and screenshots we recommend lossy WebP at quality 80–85 — the difference is invisible to the eye but the savings are dramatic. For photographs that happen to be stored as PNG (a common mistake), the savings are even larger because WebP gains over PNG-on-photo are 60–80% routinely. Tiny Pixel Kit handles batches of up to 10 PNG files at once and zips the results.

If you maintain a documentation site, a marketing landing page, or a SaaS app with a lot of UI screenshots, PNG-to-WebP is one of the highest-ROI changes you can make. Most screenshots compress so well as lossy WebP that you can comfortably keep quality at 85 and still cut weight by 70%. For logos and icons that need crisp edges, use lossless WebP — it still beats PNG by 20–35% on average. Either way, drop the file below and download the WebP result; no upload step, no waiting on a queue, no quality leak to a third-party service.
