Settings explained
- Lossless
- Pixel-perfect, larger files.
- Fill transparent areas with
- JPG cannot store transparency, so transparent pixels get this colour.
- Keep metadata (EXIF)
- Off removes camera details, dates and GPS location — safer when sharing. On keeps them.
Formats
Batch-friendly: add many files and they are processed one after another — if one fails, the rest still finish.
How it runs
- WebAssembly codecs
- Images are encoded with Squoosh-grade codecs (MozJPEG, WebP, AVIF, OxiPNG, JPEG XL). Each codec loads only when you use it.
- GPU canvas
- Pixels are drawn and composited with the GPU-accelerated canvas.
How much smaller is WebP than JPG?
Usually a third to a half smaller at the same visual quality, as long as you do not push the quality too high. Converting an existing JPG at 90% saves almost nothing, because WebP then tries to preserve the JPG’s own compression noise. The table shows one 1536 × 1024 photo (337 KB JPG) converted at different settings.
| WebP quality | File size | Change |
|---|---|---|
| 90% | 324 KB | −4% |
| 80% (default) | 205 KB | −39% |
| 70% | 157 KB | −53% |
| 60% | 139 KB | −59% |
| Lossless | 1.4 MB | +322%: never use it for photos |
What WebP quality should I use?
Start at 80%. For most photos that is indistinguishable from the original JPG at normal viewing size while saving a large share of the bytes. Go to 85% for portfolio images, product close-ups and anything people will zoom into; drop to 70% for thumbnails, backgrounds and blog images shown small.
The number is WebP’s own scale, not JPG’s, so 80% in WebP is not the same as 80% in your camera or editor. Judge by eye: convert one photo at two settings and compare them side by side.
| Use | Quality | Notes |
|---|---|---|
| Thumbnails, small blog images | 65–70% | Detail is too small to matter |
| Standard web photos | 75–80% | The default sweet spot |
| Portfolio, products, zoomable images | 85% | Keeps fine texture |
| Archive copies | Keep the JPG | Re-encoding never improves quality |
Does WebP keep EXIF data?
It can. WebP has a place for EXIF metadata, and this converter fills it when you switch on Keep metadata (EXIF) under Advanced settings: camera, lens, date and GPS location carry over. By default the setting is off, which strips the data. For a public website that is usually what you want, because a phone photo’s EXIF can reveal where it was taken.
Either way, photos come out the right way up: the rotation stored in the JPG is applied to the pixels, so the WebP does not depend on an orientation flag that some apps ignore.
What is a JPG file, and why replace it on the web?
A JPG file is a photo compressed with the JPEG method from 1992, still the most widely supported image format there is. Its compression is old, though: WebP, designed for the web in 2010, describes the same picture in fewer bytes. Keep JPG for sharing and printing, where compatibility wins, and serve WebP on your own pages, where every kilobyte affects loading time.
Convert JPG to WebP for WordPress and other sites
Resize first, then convert. A 4000-pixel phone photo in an 800-pixel column wastes most of its bytes, so set Max size (longest side) to the largest width your theme displays (1920 or 2048 px covers full-width layouts). Convert at 75–80%, upload the WebP files, and keep your original JPGs offline. WordPress accepts WebP uploads since version 5.8, and every current browser displays the format.
Why use this JPG to WebP converter
- JPG to WebP in bulk. Convert an entire gallery in one run and download a single ZIP.
- Private. Photos are converted on your device; no server receives them, which also means no size or count limits.
- Your metadata choice. Location and camera data removed by default, kept on request.
- Free and offline-capable. No account, no watermark, and it keeps working without a connection once loaded.
Tips & troubleshooting
Converting graphics, logos or screenshots instead of photos? The PNG to WebP converter defaults to lossless mode, which suits them.
Want a before/after comparison or an exact size in KB? Use the image compressor with WebP output.
Have WebP files that an app refuses? WebP to JPG converts them back.
JPG to WebP Converter FAQ
How much smaller is WebP than JPG?
Typically 30–50% at a similar look. Our 337 KB test JPG became 205 KB at 80% and 157 KB at 70%. At 90% the saving almost disappears, so stay around 75–85%.
What WebP quality should I use?
80% for most web photos, 85% for images people zoom into, 70% for thumbnails. The scale differs from JPG’s, so compare by eye rather than matching numbers.
Does WebP keep EXIF data?
Yes if you switch on Keep metadata (EXIF): camera, date and GPS are written into the WebP. It is off by default, which removes them for privacy.
Does converting JPG to WebP lose quality?
Slightly, because both formats are lossy and the photo is compressed a second time. At 75–85% the difference is not visible. Always convert from the best original you have.
Can I convert JPG to WebP in bulk?
Yes. Select all your photos, convert once and download a ZIP. There is no limit on the number of files.
