Make WebP copies of your JPG photos
Convert JPG to WebP when your website or app accepts WebP and you want another option for delivering photographs. A useful result balances file size against visible detail at the dimensions where visitors will see it.
WebP is not automatically smaller in every case. A JPG may already be heavily compressed, or your WebP quality setting may favor detail over size. Compare the actual output instead of expecting a fixed percentage reduction.
Your original JPG remains the right place to start for future exports. Treat the WebP as a delivery copy, not a replacement for your only source image.
How to convert JPG to WebP
- Choose the JPG photos you want to convert.
- Select a WebP quality setting suitable for the intended display size.
- Process the images, compare the copies and download your WebP files.
No account is needed, and picture processing takes place in your browser. The tool accepts batches of up to 30 files with 160 MB of combined input. Each JPG must stay within 40 MB and 24 megapixels.
Keep the browser tab open while the conversion runs. For a photo-heavy collection, start with a few different subjects so you can judge whether one quality setting works across the batch.
Choose quality using the picture, not only the number
The quality slider is not a universal visual score. Judge the actual image and file size instead. The same number does not guarantee an identical appearance or file size across different photographs.
Inspect the areas that matter for your use. For a product image, check printed labels, fabric texture and the outline of the item. For a portrait, look at hair and eyes. For a landscape, inspect foliage, distant detail and gradual changes in the sky.
View the WebP at the expected display size as well as a closer zoom. If the picture will appear as a small card, you may not need the same export setting as a full-width photograph that visitors can enlarge.
Resize before making a smaller web image
Converting JPG to WebP changes the file format, but it does not make an oversized photograph fit its final layout by itself. Dimensions and compression both affect the delivered file.
If your image will be displayed much smaller than its source, use the resize tool to make an appropriately sized copy. Keep the aspect ratio so faces and products do not become stretched. Then review WebP quality for that size.
Do not shrink the only original. Keeping a full-size JPG lets you create another version later for a larger layout, print work or a different destination.
Check that your destination accepts WebP
Before replacing a collection of JPG files, test a WebP upload in the site or app that will receive it. An image format can be useful for one workflow and unsupported by another.
Also check how you will share the asset outside that site. A partner may explicitly request JPG, a document tool may expect PNG, or an upload form may restrict extensions. Retain a source copy so you can produce the format each destination asks for.
The converted file is a still image. This tool does not turn a set of JPG photographs into an animated WebP sequence.
Avoid repeated lossy exports
JPG normally already contains compression decisions. Converting it to a lossy WebP can add new changes, even if those changes are difficult to see at normal size.
Use the best available JPG as the input. If you have access to a less-compressed original, use that when practical. Avoid taking a WebP delivery copy, converting it back to JPG, editing that result and converting it to WebP again.
For an image with small text or line art, inspect especially carefully. A screenshot is a different kind of content from a photograph and may need a different quality choice or output format.
JPG to WebP questions
Will JPG to WebP always reduce file size?
No. The source, dimensions and export quality determine the result. Compare the finished files and use the version that meets your visual and delivery requirements.
Can WebP conversion remove my background?
No. A JPG contains a solid picture, including its background. Use the background remover first if you need a cutout; format conversion alone does not separate the subject.
Can I convert several JPGs together?
Yes, within the batch limits. Check a varied sample of the resulting WebP images before publishing the full set.
Does a higher quality setting restore lost detail?
No. It can limit additional compression changes, but it cannot recover information that the source JPG no longer contains.
Should I delete the original JPG files?
Keep them if you may edit or export again. A delivery format is useful for distribution, while a retained source gives you more options later.
