About this tool
WebP typically produces a smaller file than JPG at similar visual quality, which is why it has become a common choice for websites and product galleries. Because JPG is already lossy, converting to WebP means re-encoding one lossy format into another — the goal is a lighter payload rather than better fidelity. Use this when you need faster page loads, cheaper storage, or a single modern asset to serve from a CDN. Every step runs inside your browser, so the JPG you pick is never sent to a server. It handles one file per run, up to roughly 25MB.
FAQ
In most cases yes, but heavily compressed JPGs occasionally end up close in size.
No. Conversion happens inside your browser tab.
All modern browsers support WebP, though very old ones may need a JPG fallback.
There is nothing to keep — JPG cannot store transparency in the first place.
More about this tool
How it works
- Choose a JPG from your device or drag it into the upload area.
- The browser decodes the JPG and encodes the pixels as a WebP image.
- Download the WebP file when it appears in the results panel.
Features
- Aim for weight, not quality — Expect a smaller file at comparable perceived quality, not a sharper image.
- Good for web delivery — WebP is widely supported by modern browsers and works well for hero images and thumbnails.
- Transparency stays absent — JPG has no alpha channel, so the WebP output is fully opaque.
- One-and-done — Encoding uses lossy WebP by default, which is what makes the size savings possible.
- On-device conversion — The file is processed locally, never uploaded.
Supported formats
Input: JPG. Output: WebP.
Input
-
JPG jpg, jpeg
Output
-
WebP webp
Common uses
- Optimising website images — Replace heavy hero JPGs with lighter WebP versions to cut page weight.
- Preparing gallery assets — Product and portfolio photos often shrink noticeably when moved to WebP.
- Saving on storage — Batch-convert JPG exports to reclaim disk space in an image library.
Limitations
- Very old browsers may not display WebP.
- Because JPG is already lossy, converting adds a second encode pass.
- Maximum file size is around 25MB, one image per conversion.
- Output remains fully opaque; no transparency is introduced.
