How to convert PNG to WebP
- Choose or drop one or more PNG files.
- Set the quality (50 to 100, default 85); 100 keeps the most detail.
- Download each WebP, or all of them as a ZIP.
Where this file comes from
PNG comes from screenshots, design tools, game captures and exported logos and icons. Developers and bloggers convert to WebP because it is the usual way to make web graphics lighter without giving up transparency.
What changes in the conversion
The PNG is decoded and re-encoded as WebP at the same size, with no resizing.
- Kept: image dimensions and transparency.
- Converted: pixels are re-encoded as WebP at the quality you set. A color profile, if present, becomes sRGB.
- Dropped: EXIF/XMP metadata, 16-bit color depth (saved as 8-bit), and all but the first frame of an animated PNG.
At lower quality settings, text and thin lines can show faint artifacts, so zoom in on important graphics before replacing the originals.
Size limits and browser notes
- Accepts .png files up to 50 MB each.
- You can convert several files at once; they download together as one ZIP.
- Everything runs in your browser, so very large files depend on your device's memory.
Works in current Chrome, Edge, Firefox and Safari. If your browser cannot save WebP itself, a WebP encoder from this site loads, so the first conversion is slightly slower.
FAQ
Is transparency kept when I convert PNG to WebP?
Yes. WebP supports an alpha channel, so transparent and semi-transparent pixels stay transparent. The report lists transparency under kept.
Is the conversion lossless?
No. The pixels are compressed lossily at the quality you set (85 by default). At 100 the result is very close to the original, but not guaranteed to be pixel-exact, and the file is larger. If you need an exact copy, keep the PNG.
How much smaller will the WebP be?
Photos and screenshots often shrink a lot. Small flat icons may barely change. Compare the original and new size shown for each file.
What gets dropped?
EXIF/XMP metadata is dropped and a color profile is converted to sRGB. A 16-bit PNG is saved as 8-bit, and an animated PNG keeps only its first frame.
Can I convert many files at once?
Yes. Drop several PNGs and take the results singly or as a ZIP. Each file can be up to 50 MB.
