PRACTICAL GUIDE
How to use Image to WebP
Last reviewed
Convert a JPG or PNG to WebP without sending the image to a remote service. WebP can reduce transfer size while preserving useful visual quality, but the best result still depends on the source image and chosen quality.
How to use it
- Select a JPG or PNG from your device
- Choose the output quality
- Convert and inspect the reported dimensions and file size
- Download the WebP while retaining your original
Converting a large photograph
- Input
- A 2400 x 1600 JPG at quality 82
- Result
- A WebP file with the same pixel dimensions
The browser decodes the source pixels and encodes a new WebP. File-size savings vary with image detail and the original compression.
Limits and assumptions
- Conversion does not improve a low-quality source
- Metadata and color-profile handling can differ between browsers
- Always compare visual quality before replacing an original
Frequently asked questions
Does the image leave my device?
No. The selected file is decoded and encoded by browser APIs on your device.
Will WebP always be smaller than JPG?
No. Detailed images, already optimized files or high quality settings can produce a similar or larger file.
Should I delete the original image?
Keep the original as your source. Treat the WebP file as a delivery copy.
