Look for the best jpg to webp converter for windows PC or mac
Hi all,
The photos taken are my iPhone saved as JPG. The problem is that the image size is pretty big and it is not suitable for the internet. Now, WebP is recommended by Google for using in web page. Unfortunately, the built-in photo viewer app on Windows and Mac don't support .jpg to .webp conversion.
Please kindly recommend the best jpg to webp converter that supports bulk conversion on Windows and Mac. By the way, I have roughly 500 jpgs to be converted to webp.

I personally use https://simplewebp.com/
It says only 5 right now for free but it's worked for me for as many as I want so far for free.
You can also CROP and scale images, adjust percentage compression, it's pretty sick.
And PNGs it retains the transparency which is amazing.

When you convert JPG to WebP. If your images are big, uploading them can take ages, especially if your internet isn’t blazing fast. Plus, it eats up bandwidth and can be annoying if you have lots of images. Uploading sensitive or private images to online servers isn’t always a great idea. You never know how they handle your data — some sites might keep copies, or worse, not have strong security measures.
If your internet connection drops or is slow, the conversion process gets interrupted. Offline tools run locally, so they’re more dependable, especially if you’re working on a bunch of images. Many free online converters only let you process a few images at a time or have size limits. Offline software is usually better for batch jobs — you can convert hundreds of images without fuss.Offline converters often give you more control — tweak compression levels, transparency, color profiles, etc. This is also my favorite way to convert JPG to WebP. Online tools tend to be more basic, which might not cut it if you need specific settings.
While online tools are handy for quick, one-off conversions, if you’re doing a lot of images, need privacy, or want more control, offline converter software on Windows (or Mac) is usually way better.

Great question — switching from JPG to WebP is a smart move since WebP usually gives better compression without losing quality. But yeah, there are a few common pitfalls you wanna dodge to make sure everything goes smoothly.
- Most JPG to WebP converters let you tweak quality levels. If you set it too low, your images can look pretty crappy. Too high, and you don’t get the size benefits. Play around with the sliders or settings to find that sweet spot.
- JPGs don’t have transparency, but WebP can. If you’re converting images that need transparency, double-check that the converter handles it properly. Otherwise, you might lose transparent backgrounds or get unexpected results.
- Some free JPG to WebP converters are buggy or don’t produce optimal WebP images. Do a quick check for reviews, or stick with well-known, reputable tools like XnC0nvert, 1rfanView (with WebP plugin), or command-line tools like cwabp from Google.
- Before converting your entire folder, do a test run on a handful of images. Check if the quality, transparency, and size are acceptable. That way, you avoid surprises later.
- Some JPG to WebP converters mishandle color profiles, leading to dull or off-color images. Make sure your converter supports proper color management if color fidelity matters.
- A WebP image might look fine on your PC but might have issues on other devices or browsers. Do a quick check on different platforms if possible.
