JPG to WebP Converter
Convert JPEG (JPG) files to WebP right in your browser. Free, unlimited batch, and your photos never leave your device.
Your files never leave your device — conversion runs locally in your browser.
To convert JPG to WebP, drop your photos above — they are re-encoded right in your browser and never uploaded. Expect files roughly 25-35% smaller at the same visual quality, which is why the web serves WebP. EXIF metadata isn't carried into WebP output, so keep your originals as the archive copy.
Honest limits
- WebP output is lossy re-encoding — keep originals as your archive copy.
- EXIF metadata isn't carried into WebP files.
Need more than a browser can do? Desktop browsers go further than phones — and Media Moana converts at scale on hosted infrastructure.
How it works
Drop your files
Drag JPG files into the drop zone, click to browse, or paste from the clipboard. Whole folders work too.
Convert locally
Each file is decoded and re-encoded to WebP right in your browser — no upload, no queue. Adjust quality or size first if you like.
Download
Save converted files one by one, or download the whole batch as a ZIP. Originals stay untouched on your device.
About the formats
JPG — JPEG
JPEG (.jpg) is the most universally supported image format in existence. Every browser, OS, app, printer, government form and photo lab accepts it. It uses lossy compression tuned for photographs, supports EXIF metadata, and at quality 85–95 is visually indistinguishable from the source for most photos — the safe default whenever compatibility matters.
WebP — WebP
WebP is Google's web image format, supporting both lossy and lossless compression plus transparency and animation. It typically produces files 25–35% smaller than JPEG at the same quality, which is why so many websites serve it — and why images saved from the web often arrive as .webp files that desktop software and upload forms reject.
Frequently asked questions
Is this safe? Do my photos get uploaded?
No upload happens — ever. Converting JPG to WebP runs entirely inside your browser using WebAssembly. Your files never leave your device, nothing is stored on any server, and the tool even keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
Does converting JPG to WebP lose quality?
WebP uses lossy compression, so technically yes — but at the default quality setting the difference is invisible for normal viewing and printing. You control the quality slider: higher values mean larger, more faithful files. Your original JPG files are never modified.
Can I convert multiple JPG files at once?
Yes — drop in as many files as you like. Because conversion happens on your own computer instead of a server, there is no per-file fee, no daily cap and no waiting in line. Files are processed one after another, and you can download each WebP file as it finishes or grab the whole batch as a single ZIP.
How much smaller will my photos get?
Typically 25-35% smaller than the source JPG at the same visual quality — that's WebP's whole pitch, and why websites serve it. The savings depend on the photo: clean, smooth images compress best, heavily detailed or already-recompressed ones less. The before/after size shows next to every file, so you can judge per photo.
Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here converting JPG to WebP happens on your machine, so the only practical limit is your device's memory. Desktop browsers comfortably handle very large files and big batches.
