JPG to WebP: help & limits

Create a WebP version of a JPG for a website, product listing or app that accepts WebP. The output keeps the decoded photo’s pixel dimensions, including supported EXIF orientation. Compare the result and file size before replacing your original. WebP can be smaller, but the saving depends on your image and browser encoder.

How to use

1. Choose a JPG or JPEG photo.
2. Wait for the WebP preview, then compare it with the original.
3. Download the WebP and check that your destination accepts the format.

Supported files

JPG / JPEG · Up to 64 MiB · 64 megapixels. One image at a time. Maximum 16,384 pixels per edge and 128 MiB output.

How it works

The browser decodes the JPG and writes a WebP at quality 92 out of 100. This introduces another lossy encoding step. No sharpening, upscaling or detail reconstruction is performed. Use the compressor if you want to tune quality.

Examples

Limitations

• The browser must support WebP encoding; an unsupported browser returns an error without a substitute file.
• Lossy WebP does not recover detail missing from a JPG. File size can increase, especially when the source is already heavily compressed.
• The limit is 16,384 pixels per edge. Metadata, HDR and exact color-profile behavior are not preserved as a guarantee.

Privacy

JPG decoding and WebP encoding run in a local worker. Neither the photo nor its filename is sent to a converter or saved by Reqly.
