What this PNG to WEBP tool does
The image is decoded and exported to WEBP by your browser, without a document upload. The tool exports a single still image, not an animation. Transparency can be retained where the source contains it. A new format does not restore detail already lost from the source.
When to use PNG and WebP
PNG stores still images with lossless compression and can preserve transparent areas. Screenshots, logos, interface graphics and images that need transparency.
WebP is an image format used on websites to reduce image transfer sizes. Some older apps do not accept WebP. JPG or PNG may be easier to use in an upload form. This release handles a still image rather than preserving animation.
Processing and limits
One image at a time, up to 50 MB and 40 megapixels. Transparency is kept where the source has it. Your browser must be able to export WEBP.
Files are processed in your browser. Keep this tab open until the download is ready; large files can exceed the memory available on your device.
How to use PNG to WEBP
- Drop one PNG into the box, or press Choose files. The tool takes one image at a time, up to 50 MB and 40 megapixels.
- Press Convert. Your browser must be able to export WEBP. Transparency is kept where the PNG has it.
- Download the WEBP and compare its size with the PNG.
- Keep the PNG as your master copy and use the WEBP where smaller files help.
Problems and quick fixes
- The WEBP is bigger than the PNG. This tool saves a lossy WEBP. For flat logos and simple graphics the PNG can already be smaller, so keep the PNG.
- The tool says my browser cannot make a WEBP. WEBP export depends on your browser. Update it, or try another current browser.
- Edges and small text look slightly softer. Lossy compression can soften sharp edges. Use PNG for screenshots and text-heavy images.
- Transparent areas look different in another program. Programs show transparency in their own way. Place the file on a coloured background to check.

Are my files uploaded?
The tools available now run in your browser, and the contents of your files are not uploaded to our conversion service.
Can any file become any other format?
No. Only supported pairs are offered, such as JPG to PNG, WEBP to JPG or images to PDF, and each tool page explains its limits.
Is it free?
Yes. The free allowance is five successful conversions a day, resetting at 00:00 UTC, and you do not need to sign in. A conversion only counts when it succeeds, and downloading a result again does not count again.
Will conversion improve quality?
Changing format cannot restore detail lost earlier. Re-saving a JPG or WEBP file may reduce quality. Keep the original and check the result before using it.
