WebP is Google’s modern web image format, supported by every current browser. It compresses roughly 25–35% smaller than JPEG at equal visual quality, supports transparency like PNG, and does both lossy and lossless modes — the pragmatic default for images shipped on websites today.
JPEG is the universal format for photographs. Its lossy compression is tuned for natural images — smooth gradients, real-world detail — and produces small files at quality levels that are visually indistinguishable from the original. It has no transparency support.
Yes — free, unlimited and without watermarks. Conversion runs on your own machine, so there are no server costs behind it.
No. Your browser decodes the WebP file and re-encodes it as JPG locally using the Canvas API. Nothing is transmitted anywhere.
JPG cannot store transparency, so transparent pixels are filled with the background colour — white unless you change it. If the image is a logo or a cut-out that needs to sit on any background, convert to PNG or WebP instead.
Yes — drop any number of files and convert the whole batch in one click. A single result downloads as a file; a batch arrives as a ZIP, and each row shows the new dimensions and the size change.
JPG uses lossy compression and cannot store transparency. Transparent pixels are filled with the background color, and lowering the quality setting permanently discards more image detail.
