What this tool is good at
When to use JPG to WebP
Photography-heavy pages
Convert camera and stock-photo JPEGs when you want smaller modern assets without changing their displayed dimensions.
Content publishing
Prepare article thumbnails, product imagery, and social graphics before they enter a CMS or static-site repository.
Private batch cleanup
Process a folder of personal or client images locally when uploading originals to a third-party converter is inappropriate.
How to choose the right settings
Start near quality 82
This is a practical balance for ordinary photographs. Inspect faces, hair, foliage, gradients, and text before choosing a lower value.
Keep original dimensions
Conversion changes the encoding, not the pixel size. Use the WebP Resizer separately when dimensions also need to change.
Compare actual bytes
A WebP is not guaranteed to be smaller than every JPEG. Keep the new file only when its visual quality and measured size suit the destination.
Practical workflow and output details
JPG already uses lossy compression, so converting it again cannot restore detail removed by the original encoder. The selected quality controls the new WebP encode, not the source quality.
Browser canvas creates a fresh image stream. Orientation should be visually normalized by modern decoders, while EXIF, XMP, comments, and embedded color-profile data are intentionally not copied.
Format behavior and limitations
Re-encoding is lossy at the selected quality.
The output does not preserve source metadata or ICC profiles.
Frequently asked questions
Are my JPG files uploaded?
No. The browser decodes and re-encodes each image on your device.
Does conversion preserve EXIF metadata?
No. This native browser encoder creates a new WebP file and removes EXIF, XMP, and ICC metadata.
What quality should I choose?
80 is a strong general starting point. Use a higher value for detailed photography or a lower value for smaller files.
