What happens to your image?
The JPG is decoded and encoded again as a WebP still image. WebP may use fewer bytes at an acceptable visual quality, but a small or already optimized JPG can produce a larger result. The site shows both actual sizes.
Start around quality 80 for a photo, then check fine texture and edges before replacing the original JPG.
Make a WebP copy of a photo
WebP is useful when a website or app accepts it and you want to compare a different photo encoder against your JPG. Upload one still JPG, choose a quality setting and save the WebP only if its visual result and measured byte size suit your destination. The converter never claims a fixed percentage saving.
Converting does not add transparency to a JPG or recreate information its earlier compression removed. Retain your JPG if a recipient asks specifically for JPEG, or if you need the original for future editing.
Quality and delivery details
The service decodes the source, applies orientation, drops original metadata and writes a new WebP file in memory. Lower quality can reduce size but may soften texture or text. The returned file is downloaded from the response; it is not stored as a media job or published as a URL.
Upload, process, save.
- Choose a supported still image from your device.
- Set quality or width when the tool offers a control.
- Process the image, compare the actual sizes, and save the result.
No account is required. Animated, broken and oversized images are rejected.
Frequently asked questions
Will WebP always be smaller than JPG?
No. It depends on the image and chosen quality; compare the displayed original and output byte sizes.
Can WebP fix JPG artifacts?
No. The original JPG's lost detail and artifacts remain in the decoded pixels.
Does this preserve camera metadata?
No. The image is rebuilt from pixels so source EXIF details, including location metadata, are not copied.
Which file type fits your next step?
Compare JPG, PNG, WebP and HEIC for compatibility, transparency and quality before converting.
