Our test: one photo, five settings
What really makes a JPG smaller?
We took a 1600 × 1067 JPG photo from this website. The original file was 172 KB. Then we converted it with different settings in this tool.
Two things stood out. First, 90% quality saved very little, because the JPG was already compressed. Second, resizing to 1280 px saved more than any quality change. So for blog photos, resize first. Then pick a quality between 70% and 80%.
Which quality should you choose?
There is no single best number. It depends on where the photo will appear. Use this table as a starting point:
| Where the photo goes | Quality | Width |
|---|---|---|
| Big header or hero image | 80–85% | 1920 px |
| Photo inside a blog post | 75–80% | 1280 px |
| Product photo with zoom | 85% | 2000 px |
| Small thumbnail | 70% | 400–800 px |
| Background behind text | 60–70% | 1920 px |
Why use a JPG to WebP converter?
- Faster pages. Photos are often the heaviest part of a page. Smaller photos load sooner.
- Less mobile data. Visitors on slow networks see your page faster.
- Better page speed scores. The largest image on a page often decides how fast it feels.
- Lower hosting costs. Smaller files use less bandwidth each month.
Why is my WebP sometimes bigger than the JPG?
This happens when the JPG is already very compressed. WebP cannot squeeze much more out of it at a high quality setting. The tool shows an orange badge when the new file is bigger. Lower the quality or resize the photo. If it is still bigger, keep the JPG.
Avoid repeat conversions. Each lossy save removes a little detail. Always convert from your best original photo, not from a file that was already converted.
What happens to photo details like location?
Camera photos often hold hidden data called EXIF. It can include the camera model, date and even GPS location. This converter does not copy that data into the WebP file. That keeps your location private when you share photos online. The picture is still turned the right way up.

Final thoughts
Converting JPG to WebP is a quick win for any website. Our test showed a clear pattern. Quality changes helped, but resizing helped even more. A 172 KB photo dropped to just 51 KB once we resized it to 1280 px and saved it at 80% quality. That is a 70% saving with no visible loss on a normal screen.
Start with your best original photo. Pick a sensible width for the place it will appear. Then choose a quality between 70% and 85%. Keep the original JPG for printing and sharing. This free converter does all of this in your browser. Your photos stay private, and your pages get faster.
