Convert PNG to WebP Online
Converting PNG to WebP is a common task whether you are preparing images for a website, a document, a presentation, or an upload form that only accepts WebP files. Our free PNG to WebP converter takes care of the entire process in your browser: you pick a file, choose the WebP options that suit your needs, and download the result.

Why Convert PNG to WebP?
The conversion runs on a server using the WebP encoder, which means you get a genuine WebP file rather than a repackaged one. PNG is a lossless raster format that keeps every pixel intact and supports full alpha transparency, which makes it the go-to choice for logos, screenshots, and graphics with sharp edges. WebP is a modern format from Google that combines strong compression with alpha transparency and optional animation support, typically delivering smaller files than JPG or PNG at similar quality.
You can adjust the WebP quality setting: higher values preserve more detail and produce larger files, while lower values shrink the output size at the cost of some visual detail.
Benefits of WebP Conversion
- Smaller WebP file sizes: The WebP encoder compresses your image efficiently, which helps the output load faster on websites and fit easier into upload limits.
- Transparency is preserved: WebP supports alpha transparency, so transparent areas from the original PNG image carry over to the result.
- Quality control: Choose the WebP quality level that fits your project — a slider lets you trade file size against visual detail before you download.
- Privacy-friendly processing: Your image is processed in memory and deleted after the download. Nothing is stored on the server and no account is required.
- No software installation: Everything happens online in your browser. You can convert on any device with a modern browser — desktop, tablet, or phone.
Limitations to Keep in Mind
- Since WebP uses lossy compression, converting from a lossless PNG introduces some compression artifacts, especially in text, sharp edges, and gradients.
- Re-encoding already-compressed PNG files can accumulate artifacts if you convert repeatedly; it is best to convert from the original image whenever possible.
- Metadata such as EXIF data is stripped from the output by default, so camera details and location information are not carried into the converted file.

Conversion Questions
Why does my PNG with transparency need a background color?
WebP does not support alpha transparency, so transparent pixels must be filled with a solid color. White is the default; choose any color that suits your design before converting.
Which WebP quality should I choose?
Start with 85 for photos and 70 for simpler graphics when you need small files. If detail is important, use 90 or above. You can convert the same image a few times with different settings and compare the file size.
Is there any quality loss converting PNG to WebP?
Yes, WebP is a lossy format, so the encoder discards some detail to save space. The higher the quality setting, the closer the output is to the original.
Does the output WebP support animation?
The converter always produces a single static frame. Animated output is not generated, so motion in the source file is not carried over.
Are my images saved or shared?
No. Uploads are processed in memory and discarded immediately after conversion. The server does not store, log, or reuse your images.
Will my photo metadata (EXIF) be kept?
No. Metadata is stripped from converted files by default for privacy, so camera settings and location data are not included in the output.
Will the converted image look different?
Minor differences are normal when the target format uses lossy compression. Use a higher quality setting to keep more detail, or convert from the original file rather than a previously compressed one.
What are the upload limits?
Files must be 10 MB or smaller and no larger than 40 megapixels. Larger images are rejected to keep processing fast and safe.
