About image tools
Every tool in this category is built on the same two browser features: createImageBitmap, which decodes a picture, and OffscreenCanvas, which re-encodes it. Both have been in every major browser for years, which is why converting between JPG, PNG and WebP needs no plugin, no upload and no waiting in a queue — your machine already has the codecs. That has a consequence worth understanding when you choose a target format. JPG is lossy and has no alpha channel, so it is the right answer for photographs and the wrong one for logos, diagrams or anything with transparency, which it will flatten onto white. PNG is lossless and keeps transparency, which makes it correct for graphics and needlessly heavy for photographs. WebP is the modern compromise: it compresses roughly a third smaller than JPG at matching quality and keeps an alpha channel, and every browser released since 2020 can display it. The one thing none of these tools can do is invent detail that was already discarded — converting a heavily compressed JPG to PNG produces a larger file containing exactly the same flaws. Convert from the best copy you have, not from something already squeezed.
Every tool runs entirely in your browser. Your files are never uploaded to a server.
