Why convert JPG to WebP
WebP is a modern image format that produces noticeably smaller files than JPG at equivalent quality, which speeds up page loads and improves Core Web Vitals.
Every major browser now supports WebP, so it's a safe default for images on the web.
How it works
Add your JPG files, choose a quality level, and each image is re-encoded as WebP on your device. Nothing is uploaded — the conversion uses your browser's own canvas engine.
Format comparison
| JPG (source) | WebP (output) | |
|---|---|---|
| Compression | Lossy | Lossy (more efficient) |
| Typical photo size | ~81 KB | ~19 KB |
| Transparency | No | Yes |
| Support | Universal | All current browsers |
Input & output compatibility
Accepts
- JPG / JPEG
Produces
- WebP (lossy, quality 60–100)
Re-encoding an already-lossy JPG to WebP shrinks it further; keep quality ≥ 80 to avoid stacking two rounds of visible compression.
Real file-size examples
WebP typically stores the same photo in a fraction of a JPG's size:
Photograph — 1600 × 1067 px
For the web, WebP is a clear upgrade over JPG — meaningfully smaller pages and faster loads. Keep a JPG copy only if you need to support very old software.
When should you use each format?
There is no single best format — each wins for a different kind of image. Use this as a quick decision guide:
Common problems & solutions
The photo looks softer than the JPG
You're compressing already-compressed data. Raise the quality slider (85–90) or start from the original, uncompressed image.
Need it to work in an old email client or app
Some legacy clients don't render WebP. Use the JPG-to-PNG or keep the JPG when the destination can't display WebP.
Is this private?
This JPG-to-WebP conversion runs entirely in your browser using the built-in canvas and WebAssembly engine. Your files are read from local memory, processed on your own device, and never uploaded to a server.
Because nothing leaves your machine, there is no upload wait, no queue, and no copy of your image sitting in someone else's storage. Closing the tab discards everything — we keep no logs of the files you open and have no account system that could retain them.
That also means it works offline once the page has loaded, and there is no per-file limit imposed by an upload quota — the only ceiling is your device's available memory.
Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
Is WebP smaller than JPG?
Usually yes — WebP typically saves 25–35% versus JPG at the same visual quality, which is why it's popular for web performance.
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox and Safari all support WebP, so it's safe to use on modern websites.
Can I convert several images at once?
Yes. Drop or select multiple files and they'll be processed in a controlled queue so your browser stays responsive. Each file shows its own progress, and you can download them individually or all together as a ZIP.
