Image converter
WebP uses more modern compression than JPEG, which dates from the early 1990s, and it generally reaches the same perceived quality in fewer bytes. The saving on a typical photograph is substantial rather than marginal, which is why it is worth doing in bulk across a site rather than case by case.
Your JPG has already been through lossy compression once. Converting it to WebP compresses it again, so in principle you are stacking one generation of loss on another. In practice, at the high quality setting this tool uses, that second generation is very hard to spot on photographic content. What you should not do is run a file back and forth between formats repeatedly — each round trip costs a little more detail, and none of it comes back.
Treat the WebP as a derived, disposable copy and keep the JPG as your master. If you later need a different size or a different format, going back to the original JPG will always beat converting the WebP a second time.
Convert JPG to PNG in your browser — the file never leaves your device. No size cap, no sign-up, no watermark, and no daily conversion limit.
Convert PNG to WebP in your browser and keep the transparent background intact. Far smaller files than PNG, with no upload, sign-up, or size cap.
Convert BMP to WebP in your browser with a quality slider. Turn huge bitmaps into web-friendly files — no upload, no watermark.
Rasterize SVG to WebP in your browser with a quality slider. Smaller than PNG for many graphics — nothing is uploaded, no account needed.
Convert ICO to WebP in your browser with a quality slider. Smaller than PNG for many icons — nothing is uploaded, no watermark added.
Convert AVIF to WebP in your browser with a quality slider. Both are web formats — use when a pipeline wants WebP instead of AVIF.
