Before you convert
Re-encoding a JPEG cannot restore detail it already lost. Lossless WebP from a JPEG source is often larger than the original.
Re-encode JPEG photos as smaller WebP files
JPEG already compresses photos well, but WebP often reaches similar quality at a smaller file size. This tool re-encodes an existing JPEG as WebP.
Because the source is already lossy, choose lossy WebP mode for real size savings. Lossless mode preserves the decoded JPEG pixels exactly but usually produces a larger file than a lossy encode.
Useful situations
- Reduce website photo sizes without changing resolution.
- Move a collection of JPEGs into a more efficient modern format.
- Compare quality presets when preparing images for mobile delivery.
How to use JPG to WebP
- Select a JPG or JPEG file within the size limit.
- Choose a quality level — 80–90% is a good starting point for photos.
- Convert and compare the WebP with the original before replacing it.
What to expect
- Re-encoding cannot restore detail the original JPEG already discarded.
- Lossless WebP from a JPEG source is often larger than the original JPEG.
- Every additional lossy re-encode compounds artifacts — convert from the best source you have.
Frequently asked questions
Is it better to convert JPG to WebP or PNG to WebP?
For photographs already saved as JPEG, converting directly keeps the workflow simple. If you also have a PNG or RAW original, use that instead — it avoids a second lossy generation.
Does JPG to WebP keep photo metadata like EXIF?
Encoders do not guarantee metadata preservation. Check the output if camera data, orientation, or copyright fields matter to you.
Why does a low-quality WebP show blocky patches?
Aggressive quantization smooths gradients into visible blocks, similar to heavy JPEG compression. Raise the quality setting or use lossless for graphics with flat colors.
