Convert PNG images to WebP format for free

PNG to WebP Converter – Free Bulk Image Converter

WebP images are 25–35% smaller than PNG and JPEG at the same quality — which means faster websites and less storage. This free PNG to WebP converter turns your PNG and JPG images into modern WebP files in bulk, right in your browser. No signup, no watermarks, no per-day limits — and unlike many converters, bulk conversion with ZIP download is completely free.

How to Convert PNG to WebP

Step 1: Drag and drop your PNG or JPG files into the box, or click to select many at once. Step 2: Set the WebP quality with the slider (85% is a great default). Step 3: Click “Convert to WebP”. Step 4: Compare original vs WebP sizes and download each file — or all of them as a ZIP.

Why Use This WebP Converter?

Bulk, free: convert dozens of images in one go and download everything as a ZIP — a feature competitors usually paywall. Transparent savings: every file shows its exact size reduction percentage. Quality control: you choose the quality level. Private: conversion happens locally; your images are never uploaded anywhere.

FAQs

What is WebP? WebP is Google’s modern image format that delivers smaller file sizes than PNG and JPEG with comparable quality. It is supported by all modern browsers.

Will transparency be preserved? Yes — WebP supports transparency just like PNG.

How much smaller will my files be? Typically 25–80% smaller than PNG, depending on the image and quality setting.

Can I convert JPG to WebP too? Yes — both PNG and JPG inputs are accepted.

Are my images uploaded to a server? No. Conversion runs entirely in your browser.

Does WebP work on iPhone and Safari? Yes. Apple added WebP support in Safari 14 (2020), so WebP images display correctly on modern iPhones, iPads, and Macs. For older devices, keep a JPEG copy as a fallback. Converting your site images from PNG to WebP is one of the easiest speed wins available.

Tips for the Best PNG to WebP Conversion

Converting PNG images to WebP is one of the simplest ways to speed up a website or shrink an image library, but a few settings choices make a big difference. The quality slider is the main control: 80% is a great default that keeps images looking identical to the PNG while cutting size dramatically. For photographs saved as PNG, you can often go down to 70% with no visible change. For logos and graphics with text, stay at 85% or higher – sharp edges show compression artefacts sooner than photos do. WebP also supports transparency, so PNGs with alpha channels convert cleanly; the official WebP documentation confirms lossless and lossy modes both preserve transparency.

Before converting a whole batch, test one representative image and compare the output size against the original – typical savings run 25-35%, and sometimes much more for large PNGs. If you need maximum compatibility, keep a JPEG copy alongside the WebP for visitors on very old browsers, though every modern browser since 2020 supports WebP natively. For websites, also remember to update your image references and consider responsive sizes; a converted WebP at the right dimensions loads far faster than an oversized PNG ever could.

• Start at 80% quality. It is the best balance for most images. Lower it only if you need smaller files and the preview still looks clean.
• Transparency converts perfectly. Unlike JPEG, WebP keeps alpha channels, so logos and icons with transparent backgrounds are safe to convert.
• Convert in batches. Processing a whole folder at once with the same setting keeps file sizes consistent across your project.
• Check browser support. WebP works in all modern browsers and phones; only very old devices need a JPEG fallback.
