Why convert PNG to WebP with frisqoo
Nothing is uploaded
Your images are read and converted inside your browser. They never reach a server, so there is nothing to delete later.
Much smaller files
A detailed PNG is often several times larger than it needs to be. WebP makes it far lighter.
Transparency kept
WebP has an alpha channel, so any see-through areas in your PNG are preserved exactly.
Quality you control
Set the WebP quality to trade file size for sharpness, or keep it high for a near-perfect copy.
A whole batch at once
Convert many PNG files with the same settings, then download them one by one or together as a zip.
Free, with no caps
No sign-up, no watermark, and no daily quota. Your device memory is the only real limit.
How to convert PNG to WebP
- Add your PNG images. Drop them on the box or pick them from your device, one or many.
- Set the WebP quality. Transparency is kept automatically, so see-through areas stay see-through.
- Press Convert. Save each WebP on its own or download them all in a zip.
When to convert PNG to WebP
PNG is great for logos, screenshots, and anything with transparency, but the files can be large. WebP keeps the same transparency while making a much smaller file, so it is a strong choice when you want light images for a website or app without giving up see-through areas. Keep a PNG when you need the widest possible support or a lossless copy; choose WebP when size matters.
Is it safe to convert images here?
Yes. Many free converters upload your images to their own servers to do the work. This tool does not. Your images are read and converted right inside your browser, so they are never uploaded, stored, or seen by anyone else. That makes it a safe choice for personal images, screenshots, and anything else you would rather keep off a server you do not control.
Common ways people use PNG to WebP
- Shrinking a heavy PNG for a website while keeping its transparency.
- Saving storage on a folder of PNG graphics.
- Preparing images for an app or theme that prefers WebP.
- Converting a whole folder of PNG files in one go and saving them as a zip.
