Why convert PNG to WebP?
PNG was designed for lossless images in the 1990s. It does its job well, but the files are large. WebP, released by Google in 2010, does the same job better — 25-35% smaller files at the same visible quality, full transparency support, and universal browser support. Website owners use WebP to load pages faster. App developers use it to ship smaller bundles. Photographers use it to save storage. If your PNG is going on the web, WebP is almost always the right choice.

PNG to WebP questions
What is WebP?
WebP is a modern image format developed by Google. It produces files 25-35% smaller than PNG at the same visible quality, supports transparency, and works in every browser released after 2020.
Why convert PNG to WebP?
PNG files are lossless and often very large. WebP gives you the same sharp image with 25-35% smaller file size. Smaller files mean faster websites, lower bandwidth and quicker load times on mobile.
Does WebP keep transparency?
Yes. WebP supports a full alpha channel, so transparent areas in your PNG stay transparent after conversion. You do not lose transparency like you would with JPG.
Does every browser support WebP?
Yes, all modern browsers do — Chrome, Firefox, Safari 14+, Edge. That covers 97%+ of users. Older browsers simply will not display the image, but they are extremely rare.
Will converting lose quality?
A tiny amount at low quality settings. At 85-90% quality, most people cannot tell the difference. WebP is more efficient than PNG so it can be smaller and look almost identical.
Is WebP good for logos and icons?
Yes. WebP handles flat colours and simple graphics very well, especially with transparency. It is a great replacement for PNG for website logos and UI icons.
Can I convert many PNG files at once?
Yes, up to 20 files at once. Download them one by one or all together as a ZIP.
Does the converter strip metadata?
Yes. Browsers do not pass EXIF data through a canvas, so GPS location, camera model and creation date are removed on every conversion.
Are my files uploaded to a server?
Never. Everything runs in your browser. Your PNG files never leave your phone or computer.
Should I use WebP or AVIF?
AVIF is even smaller (up to 50% smaller than WebP) but browser support is newer and some apps still cannot open AVIF. WebP is the safer choice for websites today. Use AVIF only when you control the display.
Can I resize while converting?
Yes. Use the Resize option to set a maximum width or exact dimensions before converting.
Is there a daily limit?
No. No sign-up, no daily limit, no charge.
