Good to know

- A few browsers cannot save WebP files. If you see an error, try Chrome, Edge or Firefox.
About the formats
PNG
PNG uses lossless compression and supports transparency. It is ideal for screenshots, logos and graphics with sharp edges, but photos saved as PNG are much larger than JPG.
WebP
WebP is a modern web format from Google. It is usually 25–35% smaller than JPG at similar quality and supports transparency, but some older apps and editors still cannot open it.
Frequently asked questions
- Will converting PNG to WebP reduce quality?
- Slightly, because WebP uses lossy compression. At the default 90% quality the difference is hard to see, and you can lower the quality to make files smaller.
- Will the WebP file be smaller?
- Usually much smaller, especially for PNGs that contain photos, and transparency is kept.
- Is transparency kept?
- Yes. WebP supports transparency too, so transparent areas stay transparent.
- Are my files uploaded to a server?
- No. All conversion happens inside your browser with JavaScript. Once the page has loaded, it keeps working even if you go offline.
- Is it free? Are there any limits?
- It is completely free, with no sign-up and no watermark. How many and how large files you can convert depends only on your device’s memory.
- What happens to the photo’s location data (EXIF)?
- Converted files do not contain metadata such as GPS location or camera details, so this tool also works as a quick way to strip location data before sharing. The image orientation is preserved.
- Does it work on my phone?
- Yes, it works in current versions of Chrome, Safari, Samsung Internet and other modern browsers. Very large images may fail on phones because of memory limits.
