AVIF is the newest generation of web image formats, based on the AV1 video codec. It beats even WebP on compression, but encoder support outside browsers is still patchy — so AVIF files often need converting to PNG or JPG before other software can open them.
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 AVIF 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.
No. The image is decoded to pixels and re-encoded from a fresh canvas, so EXIF, GPS coordinates and any embedded colour profile are not carried into the JPG file. That is usually what you want before publishing a photo; if you need the camera data, keep the original.
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.
