What you can expect
Processed on your device
Images are decoded and re-encoded in the browser. No file is uploaded for conversion.
JPG and JPEG treated alike
Both extensions mean the same format. The converter checks the file signature, not the extension.
Honest file sizes
You see the real output size of every file. If the WebP turns out larger than the JPG, it says so.
How the conversion works
- 01
Choose your images
Drag JPG or JPEG files into the field or open the file dialog. Several files at once are fine.
- 02
Set the quality
Settings appear only after a valid image has been read. The default is 90 %.
- 03
Download the results
Download single WebP files or every finished result as a ZIP archive.
Quality, orientation and format
WebP is not automatically smaller
WebP compresses many subjects more efficiently than JPG, but that is not guaranteed. Small images or already heavily compressed JPGs can grow. The sizes shown come from the actual output.
Losses cannot be recovered
A JPG is already compressed. Converting to WebP cannot restore missing detail, it re-encodes the pixels that are there. 100 % on the slider means high-quality lossy compression, not lossless.
The browser has to be able to write WebP
WebP output is produced by the browser encoder. If your browser cannot do that, the converter says so instead of naming a different file .webp.

Frequently asked questions
Are JPG and JPEG the same?
Yes. Both extensions refer to the JPEG standard. The converter accepts .jpg and .jpeg and also checks the file signature.
Is the image orientation kept?
Yes, EXIF orientation is applied while decoding so the result appears upright. The EXIF data itself is not written into the WebP file.
Is a quality of 100 % lossless?
No. Even at 100 % this is lossy WebP compression at high quality. Lossless WebP is not offered by this converter.
Will the file always get smaller?
No. The preview shows the real numbers. When WebP comes out larger, the JPG is usually the better choice.
What if my browser cannot encode WebP?
A message appears before conversion starts and nothing is processed. No substitute file with a wrong extension is created, and nothing is uploaded.
Is metadata preserved?
No. Camera and colour profile data from the source is not carried into the output. Colours match how the browser renders the source.
