JPG TO WEBP
From JPG to a WebP file
Choose the WebP quality before conversion.
Set WebP quality
WebP is preselected. Adjust quality to balance file size and image fidelity.
Download WebP
Download results individually or collect multiple files in a ZIP archive.
FORMAT KNOWLEDGE
What happens when JPG becomes WebP?
LokalPix decodes the JPG and encodes the visible pixels again as WebP. The output is lossy at the selected quality.
JPG
An already compressed source
JPG discarded image information during its first encoding. Changing formats cannot recover those details.
WEBP
For modern web delivery
WebP uses lossy encoding in this conversion. The selected quality affects file size and visible artefacts.
IMPORTANT
A smaller file is not guaranteed
The result can be smaller, similar in size, or larger than the JPG. The subject, source compression, and selected quality all matter.
FORMAT IN DEPTH
JPG and WebP compared
Both can store photographs compactly, but their encoders work differently.
From JPEG to WebP
JPEG commonly encodes photographs with lossy block-based methods. Lossy WebP uses VP8 techniques including spatial prediction, adaptive quantisation, and entropy coding. LokalPix uses the WebP encoder provided by your browser.
When WebP makes sense
WebP is useful for websites when browser support is available and the actual output is smaller. Before replacing a JPG, compare file size and visible quality using the specific image.
No retroactive repair
Conversion works with the pixels decoded from the JPG. Existing blocking, colour fringes, and missing detail remain part of the image. WebP cannot reconstruct them.
What is lost during conversion?
Another lossy encoding step can alter image detail. JPEG-specific EXIF structures and embedded previews are not transferred by default. The original JPG file cannot be reconstructed bit for bit from the WebP.

FREQUENT QUESTIONS
Questions about JPG to WebP
Answers about quality, privacy, and format limitations.
Will every WebP be smaller than the JPG?
No. It depends on image content, the JPG's quality, and the WebP setting. Compare the result for the actual image.
Does WebP improve my JPG's quality?
No. Missing detail and existing JPG artefacts remain. WebP encoding may add further artefacts at low quality settings.
Which WebP quality should I choose?
90 percent is a practical starting point for visual inspection. A lower value may produce smaller website assets; check fine detail, text, and gradients.
Will the WebP gain transparency?
The format supports transparency, but a JPG source has no alpha channel. Conversion does not automatically make the existing background transparent.
Are resolution and aspect ratio preserved?
Yes. LokalPix does not intentionally change the pixel dimensions during this conversion.
Are metadata preserved?
Metadata are removed by default. JPEG EXIF data are not transferred to the WebP output.
