What is the WebP format and why convert JPEG to WebP?

WebP is an image format developed by Google for the web. Its main advantage is that files are often smaller than JPEG files: lighter pages and less data consumption, especially on mobile devices. WebP images are commonly used for websites, blogs, and online stores. All major modern browsers support it, including Chrome, Firefox, Edge, and Safari.

Image quality and file size after converting JPEG to WebP

The converter keeps your image dimensions and re-encodes it as WebP. Since a JPEG is already compressed, small differences are possible, and no converter can recover details that the JPEG has already lost. This tool does not have a quality setting, so check the result before replacing the original.

• Start with the original JPEG, not a copy that has been saved again or sent through a messaging app.
• Keep the original JPEG as a backup.
• Keep the original dimensions. Enlarging an image does not add detail.

JPEG to WebP test: file size before and after

Our test: using this tool, we converted a 1920×1280 pixel JPEG that was 141 KB. The resulting WebP was 24 KB, about 83% smaller, with the same dimensions. Tested in Chrome on October 1, 2026. It was a flat-color logo on a white background, a type of image that compresses very well. Photographs usually shrink less, so your results will vary.

When should you convert JPEG to WebP?

• You want images to load faster on a website or blog.
• You need to reduce the overall size of many images, for example in a product catalog.
• A website or platform requires WebP files.

Keep the JPEG if you need to send the image to someone who may not be able to open WebP, or if an older program, email client, or upload form rejects this format.

Convert JPEG to WebP: frequently asked questions

Can I convert multiple JPEG files to WebP at once?

Yes. Select multiple JPEG files when uploading (up to 10 MB each) and click «Convert» once. When they are ready, you can download each WebP separately or all of them together in a single ZIP file.

How can I convert JPEG to WebP for free?

Upload the JPEG to this page, click «Convert», and download the WebP. The service is free and does not require registration. This tool only converts JPEG to WebP.

Is WebP smaller than JPEG?

Usually, yes, but it depends on the image. In our test, a 141 KB JPEG became a 24 KB WebP.

What is the JPEG format? Are JPG and JPEG the same thing?

JPEG is a widely used image format, especially suitable for photographs, that reduces file size through lossy compression. JPG and JPEG are the same format; only the file extension is different. This converter accepts both.

How do I open a WebP file in Photoshop?

Recent versions of Photoshop generally open WebP files, while older versions may not support them. If your program does not recognize the format, keep the original JPEG available.

Can I print a WebP file?

It depends on the printing service or program you use: some do not accept the WebP format. If you are unsure, use the original JPEG.

How can I convert an image from WebP to JPEG?

This tool converts JPEG to WebP, not the other way around. For the reverse operation, you need another converter or an image editor. The image will be compressed again and may lose some quality, so if you still have the original JPEG, keep it.

Can I resize a WebP file?

This tool does not change the image dimensions. If you need a different size, resize the JPEG with an image editor before converting it.

Does the background become transparent when converting JPEG to WebP?

No. JPEG does not support transparency, so the WebP keeps the same solid background. The WebP format can support transparency, but the conversion does not create it.

Can I convert a JPEG larger than 10 MB to WebP?

Each file can be up to 10 MB. If your JPEG is larger, reduce its file size or dimensions with an image editor first, then convert it.

Is renaming .jpeg to .webp enough?

No. Renaming a file does not change its actual format, and some websites will reject it. To get a real WebP file, convert the file using a tool like this one.

Is it safe to convert my images here? Are they stored?
