WebP is already set
WebP is preset as the output. The quality slider sits at a balanced default for WebP; raise it for more detail, lower it for smaller files.

Step 3
Convert and download
Each finished row shows its new WebP size next to the original. Download the files one by one — no waiting rooms, no watermarks.
Should you convert PNG to WebP?
This is the conversion web developers hope for: WebP keeps what makes PNG valuable — exact pixels and full transparency — while usually producing a much smaller file. Screenshot, logo, download banner: the WebP copy is almost always smaller and looks identical, and all modern browsers render it. The only catch is tooling: older software that predates WebP will still ask you for PNG.
In short: Choose PNG → WebP for anything headed to the web — smallest lossless-looking files with transparency intact.
| Property | PNG (source) | WebP (output) |
|---|---|---|
| Compression | Lossless — every pixel stored exactly | Lossy or lossless, very efficient |
| Transparency | Yes — full alpha channel | Yes — full alpha channel |
| Best for | Screenshots, logos, graphics with text and hard edges | Modern websites and apps where file size matters |
| Worth knowing | Pixel-exact storage makes PNG files large for photographic content. | WebP itself supports animation too — this tool exports still images only. |
PNG to WebP — frequently asked questions
How do I convert PNG to WebP?
Drop your PNG files into the converter above (several at a time is fine), confirm the output is set to WebP, then hit convert and download the results. Everything happens locally in your browser while the files stay on your device.
Does converting PNG to WebP lose quality?
At the default quality the difference is not visible in practice: the slider lets you keep more detail (larger file) or squeeze harder (smaller file) before the WebP is written. Transparency is preserved in WebP output.
Will the WebP file be smaller than my PNG file?
Almost always. WebP is the most efficient encoder the browser supports, so the copy is typically the smallest you can make of this image — transparency and visual quality included.
What happens to transparency and EXIF metadata?
Transparency survives the trip: the WebP copy keeps the same see-through areas. EXIF metadata such as camera model, timestamps and GPS coordinates is not carried over: the output is written as a brand-new file containing pixels only. That is a privacy bonus, not a bug.
Are my images uploaded to a server?
No. The converter decodes and re-encodes your images locally in your browser using Web Workers. Your files never leave your device, which is why the tool keeps working even on slow or offline connections.
