Converter PNG to WebP: Quick, Simple, and Free

If your website is packed with images, there’s a good chance they’re slowing things down. That’s where using a converter PNG to WebP can be a game-changer. This simple switch can shrink file sizes dramatically without hurting image quality and that means faster pages, better SEO, and happier visitors.

In this guide, you’ll learn exactly what WebP is, why converting from PNG matters, and how to do it online in just a few clicks.

What Are PNG and WebP Formats?

Before jumping into conversion, let’s quickly understand what these formats are:

• PNG (Portable Network Graphics) is a popular image format known for lossless compression and support for transparent backgrounds. It delivers high quality but often comes with larger file sizes.
• WebP is a modern image format created by Google. It uses both lossy and lossless compression, making images up to 30–50% smaller while maintaining visual quality.

Why this matters: Smaller files mean faster websites. Faster websites tend to rank better on Google.

Why Convert PNG to WebP?

Switching your images from PNG to WebP has several key benefits:

• Faster Load Speeds: WebP images are much lighter, cutting down page load times.
• Better SEO Performance: Google prioritises speedy sites. Optimised images help improve Core Web Vitals scores.
• Bandwidth Savings: Smaller files reduce the strain on hosting servers and users’ data usage.
• Still Looks Sharp: WebP keeps images clear even at smaller file sizes, so you don’t compromise on quality.
• Wider Compatibility: Modern browsers now fully support WebP.

If you care about SEO, user experience, or just making your site feel snappy, this is a no-brainer.

When Should You Use PNG vs WebP?

PNG images are ideal for:

• Graphics that need transparent backgrounds
• Screenshots or icons with sharp edges
• High-detail visuals where lossless quality matters

WebP is better for:

• Blog posts and web pages with many images
• Product photos on ecommerce sites
• Hero banners and sliders
• Any place where faster loading matters

In most cases, converting PNG to WebP is the smarter choice for web use.

How Much Can WebP Shrink Your File Sizes?

On average, converting PNG to WebP can cut file sizes by 30–70%. For example:

• A 500 KB PNG may become around 150 KB as a WebP
• A 1 MB PNG can shrink to 300–400 KB

This reduction translates to faster load speeds, lower bounce rates, and improved rankings — especially on mobile devices where performance is critical.

If you want to go even further, you can also compress existing WebP images down to a target size like webp to 100kb.

Pros and Cons of Converting PNG to WebP

Pros:

• Much smaller file sizes
• Maintains image quality
• Improves website performance
• SEO-friendly
• Free and quick to do

Cons:

• Older browsers (like IE) may not support WebP
• Requires an extra conversion step if editing the image later

Tip: You can always keep your original PNG files as backups while using WebP on your live site.

Batch Conversion: Handling Multiple PNGs

If you’ve got a whole folder of PNGs, converting them one by one can feel tedious. Luckily, some online converters allow batch processing. You can upload multiple images at once, click convert, and download a zip file containing all the new WebPs.

This is perfect for site migrations, blog revamps, or ecommerce catalogue updates.
