WebP quality setting guide
The quality value controls the trade-off between visual detail and file size. It is not a universal percentage of the original image quality, and results differ from one photo to another.
| Quality range | Typical use | What to check |
|---|---|---|
| 60–74 | Small previews, thumbnails or images where file size is the priority | Look for blockiness, banding and lost texture |
| 75–85 | Practical starting range for many website photographs | Compare faces, text, product edges and fine detail |
| 86–95 | Images where retaining more detail matters more than maximum savings | Confirm that the larger output is still worthwhile |
What changes when JPG becomes WebP?
- The original pixel width and height are kept.
- The visible JPG pixels are encoded again using WebP at your selected quality.
- Existing JPG compression artefacts and lost detail cannot be repaired.
- Lower quality can add further compression loss.
- EXIF, GPS and other embedded metadata are not carried into the new WebP file.
- A JPG has no transparency, so conversion does not create a transparent background.
When transparency is needed, remove the background in an editor first. For a PNG output instead, use the JPG to PNG converter.

A setting around 75 to 85 is a practical starting point for many photos. Inspect the converted image and adjust the value for your own quality and file-size requirements.
No. WebP is often smaller, but some images can produce little savings or even a larger file. The source compression, selected quality and image content all affect the result.
No. Conversion cannot restore detail already removed by JPG compression. A lower WebP quality can introduce additional compression loss.
Yes. The output keeps the decoded image width and height. The file size and encoding change.
No. The browser canvas creates a new image from the visible pixels, so EXIF, GPS and other embedded metadata are not transferred.
No. Conversion runs locally in your browser. Humanify.pro does not upload or store the images you select.
