Convert WebP to JPG — Offline
Drop one or more WebP images onto MiniMax Converter and save them as JPG. Any transparency is flattened onto a white background, and you set the JPG quality yourself. Batch a whole folder if you like — runs locally, no upload, no file-size limit, no watermark.
How to convert
- Drag one or more .webp files (or a whole folder) onto the MiniMax Converter window.
- Pick JPG as the output format in the format chooser.
- Set the quality slider — higher keeps more detail and a larger file; transparency is flattened onto white automatically.
- Click Convert and choose where to save; each JPG is written next to its source.
Quality and what to expect
WebP and JPG are both lossy formats, so converting re-encodes the picture rather than copying it pixel-for-pixel. The quality slider (5–100) lets you trade file size against detail — 90+ is visually near-identical for photos, while lower values shrink the file at the cost of visible artifacts. There is no point pushing past the detail the original WebP already contains.
Transparency becomes white
JPG has no alpha channel, so any transparent areas in your WebP can't be preserved. MiniMax Converter flattens transparency onto a solid white background before saving — the standard, predictable choice. If you need to keep transparency, convert to PNG instead, which the app also supports.
Why offline?
Online WebP-to-JPG sites cap file sizes, upload every image to a server, throttle bandwidth, and frequently bolt on ads or watermarks. MiniMax Converter does the encode on your own machine with Pillow — any size, at SSD speed, and your images never leave your computer. Batch a hundred WebP files and nothing touches the network.
Questions and answers
What happens to transparent areas in my WebP?
JPG can't store transparency, so any transparent pixels are filled with solid white before saving. If you need to keep the transparency, convert to PNG instead.
Will converting WebP to JPG lose quality?
Some, yes — both are lossy formats, so the image is re-encoded. Keep the quality slider high (90+) for results that look near-identical to the original; lower values trade detail for a smaller file.
Can I convert many WebP files at once?
Yes. Drop multiple files or a whole folder and they're all converted in one batch, processed concurrently, with each JPG saved next to its source file.
Is there a file-size limit?
No. Conversion runs entirely on your machine with no upload, so there's no size cap and no bandwidth throttling — the only limit is your disk space.
