Convert JPG to WebP
WebP typically produces files 25-35% smaller than JPEG at the same visual quality, which makes it the best default for photographs on the web.
Every current browser supports it.
How to convert JPG to WebP
- Drop one JPG file or a whole folder of them onto the upload area.
- Choose the WebP quality level.
- Compare the file sizes before and after.
- Download the WebP, or the whole batch as a ZIP.
Supported formats
This tool accepts JPG files. Everything is decoded by your own browser, so the formats available depend on what your browser can open - which for HEIC in particular varies between Safari and other browsers.
Because the image is rebuilt from raw pixels, EXIF metadata such as camera details, timestamps and GPS coordinates does not carry into the result. Orientation is applied to the pixels first, so photographs stay the right way up. Embedded colour profiles are also dropped and the output is saved as sRGB, which can shift colours slightly in wide-gamut photographs. Animated files are refused rather than being flattened to a single frame.
Frequently asked questions
Can I convert a whole folder at once?
Yes, which is the usual reason anyone comes to this page - converting a whole gallery is where WebP actually pays for itself, since the saving is per file and a single image rarely justifies the change. Each JPG is converted with the same quality setting and the results download as one ZIP. Anything that cannot be read is refused by name as you add it, so you find out before the batch runs rather than after it.
Is my file uploaded anywhere?
No. The file is converted locally, so a folder of photographs can be processed one after another without waiting on a network round trip for each one.
Is the converter free?
Yes. Free, no sign-up, no watermark. There is no paid tier that unlocks better quality either: the quality slider goes as high as the format allows.
How much smaller is WebP than JPG?
Usually 25-35% smaller at equivalent visual quality, and often more for images with large flat areas. The exact saving depends on the picture, so compare the before and after sizes the tool shows you.
Do all browsers support WebP?
Yes, every browser in current use supports WebP, including Safari from version 14 and all versions of Chrome, Edge and Firefox. Only genuinely obsolete browsers lack it.
Is converting JPG to WebP lossless?
No. The JPEG is decoded and then re-encoded as lossy WebP, so this is a second lossy pass. At quality 80 or above the additional loss is generally not visible, but always convert from the highest quality original you have.
