Why Convert PNG to WebP?
PNG to WebP conversion re-saves a PNG image in the WebP format, which usually gives a much smaller file while still supporting transparent backgrounds. It is a good way to speed up websites that use logos, icons, screenshots and graphics. WebP is supported by all current major browsers.
PNG files are great for quality, but they are heavy. A logo, a product cut-out or a screenshot saved as PNG can be hundreds of kilobytes or even megabytes. On a website, those files slow down loading, especially on mobile.
WebP was designed to fix this. Unlike JPG, WebP supports transparency, so you can shrink PNG images without giving up the transparent background. Google's published figures say lossless WebP is about 26% smaller than PNG, and lossy WebP with transparency is often several times smaller than the PNG it replaces. Real savings depend on the image and the quality you choose, and graphics with flat colours and screenshots often shrink a lot.
What smaller PNGs mean for you:
- Faster page loading and a better Largest Contentful Paint score when the image is the main element.
- Less bandwidth for visitors on slow or metered connections.
- Smaller media libraries and backups on your website or app.
- Transparency preserved, so you do not need to switch to JPG and a white box.
Be honest about the trade-off: at the default 80% quality, the conversion is lossy, so very fine detail and sharp text edges can change slightly. For pixel-perfect work such as design source files, keep your original PNG and use the WebP as the web copy.
What You Can Do With This Converter

Which Image Tool Should I Use?
Choose the format that matches where the image is going: WebP for websites, PNG for editing, JPG for photos that don't need transparency.

How to Use WebP Images With Transparency on a Website
Upload and replace
Upload the WebP files to your site or media library, then replace the PNG versions in your pages. Keep the same file names (with the .webp extension) so they are easy to track.
HTML fallback for very old browsers

Good habits
- Resize oversized images before converting. A 3000 px logo displayed at 300 px is wasted bytes.
- Use descriptive file names (teasoft-logo.webp, not image1.webp) and meaningful alt text.
- Set width and height attributes to avoid layout shift.
- Do not lazy-load the main above-the-fold image. Lazy-load the rest.
- Keep your original PNG files as masters.
When to stay with PNG
Design source files, images you will keep editing, assets for print, email signatures, and software or platforms that do not accept WebP. For those, keep the PNG, or convert WebP back using Teasoft's WebP to PNG tool.
Frequently Asked Questions
How do I convert PNG to WebP?
Open Teasoft's PNG to WebP converter, add your PNG files, set the quality (80% is a good start), click Convert to WebP and download the results as individual files or a ZIP.
Does WebP support transparency?
Yes. WebP supports transparent backgrounds, so a PNG with transparency keeps it when converted to WebP. This is the main advantage of WebP over JPG for logos and icons.
Is WebP smaller than PNG?
Usually, yes. Google reports lossless WebP is about 26% smaller than PNG, and lossy WebP with transparency can be much smaller. The exact saving depends on the image and the quality setting.
Does converting PNG to WebP reduce quality?
At the default setting the conversion is lossy, so there can be tiny changes in fine detail. At 80–90% it is usually not visible. Keep your original PNG if you need a pixel-perfect master.
What quality should I use?
80% is a good default. Use 85–90% for logos and text-heavy images, and 65–75% for large decorative backgrounds.
Is WebP better than PNG?
For websites, usually yes, because smaller files load faster and WebP keeps transparency. PNG is still better for editing, source files and software that doesn't support WebP.
Will WebP help my SEO?
WebP doesn't rank a page by itself. But smaller images improve page speed and Core Web Vitals such as Largest Contentful Paint, which are part of Google's page experience signals.
Do all browsers support WebP?
All current major browsers support WebP, including Chrome, Edge, Firefox, Opera and Safari. Some older software and apps do not, so keep a PNG or JPG fallback where needed.
Can I convert many PNG files at once?
Yes. Add up to 50 PNG files in one batch, each up to 100 MB, and download them all as a ZIP.
Are my images uploaded to a server?
No. Conversion happens in your browser, and your files are never uploaded.
Can I convert WebP back to PNG?
Yes. Use Teasoft's WebP to PNG converter. Note that converting a lossy WebP back to PNG will not restore detail lost during the first conversion.
Is the PNG to WebP converter free?
Yes. It is free, with no sign-up, no watermark and no hidden fees.
