Image quality when converting PNG to WEBP
WebP can use lossy or lossless compression. Moderate settings often reduce file size substantially while keeping good visual quality.
File size after conversion
WebP output is often smaller than PNG, especially for photographic or complex images.
What happens to image metadata?
Re-encoding can remove or change embedded metadata. Use the Strip metadata option when you want the converted copy to exclude embedded information.
Private image conversion
Supported conversions are processed locally in your browser whenever possible, so source images do not need to be routinely uploaded to a remote conversion server.
Compression presets
Presets automatically adjust compression and image size depending on how the converted image will be used.
| Preset | Compression | Max Dimensions | Typical File Size | Best For |
|---|---|---|---|---|
| Web | Medium | 1920px | 200KB – 800KB | Websites, blogs, landing pages |
| Social | Medium-High | 1200px | 100KB – 400KB | Instagram, Facebook, LinkedIn |
| High | 1200px | 50KB – 200KB | Email attachments and quick sharing | |
| Low (Highest Quality) | No resize | 1MB+ | Printing photos or marketing materials |
Actual file size depends on the original image resolution, source format, image content, and selected settings.
