Turn PNG files into WebP on your own PC with AnyFormat — no upload, no account, no watermark.
PNG is the lossless image format behind most logos, icons, screenshots and graphics with sharp edges or transparency. It never degrades the image, but that fidelity comes at a cost: PNG files are large, and a page full of them is a page that loads slowly.
WebP is a modern image format from Google designed for the web. It offers both lossless and lossy compression and, crucially, keeps transparency — so it can replace a PNG while producing a noticeably smaller file. Smaller images mean faster pages, which is something both visitors and search engines reward.
The main reason is page speed. If you run a website or a blog, swapping heavy PNGs for WebP trims payload without visibly changing the graphics, improving load time and Core Web Vitals. It’s also handy for shipping image-heavy apps or emails where every kilobyte counts. You keep the transparency you needed the PNG for in the first place.
.png, choose WebP as the target, and save.WebP comes in lossless and lossy flavours. Lossless is the safe default for logos and UI graphics where you can’t afford artefacts; lossy squeezes photographs much smaller at a slight quality cost. If you’re converting a photo rather than a graphic, expect the biggest savings there.
For most graphics and screenshots, lossless WebP is roughly 20-30% smaller than the same PNG, and lossy WebP can be far smaller again. The exact saving depends on the image.
Yes. WebP supports a full alpha channel, so transparent backgrounds and rounded corners carry over from the PNG unchanged.
Every current browser displays WebP, which is why it's a web-first format. A few older desktop programs still don't, so keep a PNG copy if you need to open the image in legacy software.
No. AnyFormat converts locally. Your PNGs are never uploaded, which matters when you're batch-processing a whole asset folder.
No account, no licence key, no email gate. If AnyFormat saved you a bad afternoon, there's a button. That's the whole business model.
