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.
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.
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.
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.
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.
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.
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.
