Convert JPG to WebP in batches, locally
Output format is set to WebP on this page. Drop JPG photos (PNG works too), convert them in your browser, and download a ZIP. Folder paths stay intact. Nothing is uploaded.
Why convert photos to WebPWebP is usually much smaller than JPEG at similar quality, which helps product pages and blogs. Converting locally avoids upload limits on a whole catalog of photos.

Select or drop multiple images, then start compression. By default, the tool aims to reduce size while preserving visual quality, and you can compare sizes after processing.

Batch JPEG to WebP without sending photos away
Online converters often reject large camera files or cap how many you can convert. Swiftiny converts in the browser: drop a folder of JPGs, keep quality around 82, and download .webp files named after the originals.
If you drop a nested catalog, the ZIP still has the same directories — only the extension changes. That makes it straightforward to swap assets on an ecommerce site.
You can switch output back to JPG or PNG in the settings. Free batches are limited to 50 images; Pro unlocks unlimited images per batch.
Frequently Asked Questions
Is JPG to WebP conversion uploaded to a server?
No. Conversion runs in your browser. Your photos are not uploaded to Swiftiny.
Can I convert a whole folder of JPEGs?
Yes. Drop nested folders. The ZIP keeps the original structure with .webp files inside. Free use allows up to 50 images per batch.
Should I use WebP instead of JPEG?
For most websites, WebP is smaller at similar quality and is widely supported. Keep JPEG if a client or CMS still requires it.
