Which format to pick
Four formats, and the choice is usually obvious once you know what each is for.
- WEBP
- The default for the web. Around 25 to 35 percent smaller than JPG at matching quality, with transparency and universal browser support since 2020.
- JPG
- The safest choice for photos going anywhere old or unknown. No transparency, and every save re-compresses, so avoid repeated round trips.
- PNG
- Lossless, with transparency. Right for screenshots, logos, and flat graphics; wasteful for photographs, where files run several times larger.
- AVIF
- The smallest files of the four, often half the size of JPG. Supported everywhere modern, though it takes a few seconds to compress rather than being instant.
Converting also drops metadata
Converting redraws the image from its decoded pixels rather than repackaging the original file, so everything wrapped around those pixels is left behind: EXIF, GPS coordinates, the camera and lens, and any C2PA Content Credentials.
That is a side effect, not a guarantee. If stripping metadata is the actual goal, the AI Image Metadata Remover does it without re-compressing the image, and the Metadata Viewer shows you what a file is carrying in the first place.

Frequently asked questions
- Can I convert HEIC photos from my iPhone?
- Yes. Drop in a HEIC or HEIF file and convert it to JPG, PNG, WEBP, or AVIF. Browsers cannot open HEIC on their own, so the tool loads a decoder the first time it sees one. HEIC is input only: there is no reason to convert a photo into a format most software still cannot read.
- Why is AVIF slower than the other formats?
- No browser can write AVIF, only display it, so this tool ships its own encoder compiled to WebAssembly. It is downloaded the first time you pick AVIF and does the compression itself, which takes a few seconds on a large photo. The other three formats are handled by the browser directly and are near-instant.
- Does converting reduce quality?
- Converting to PNG is lossless. Converting to JPG, WEBP, or AVIF re-compresses the image, so pick a higher quality setting if the result will be edited again. Converting a JPG to PNG cannot restore detail the JPG already discarded.
- What happens to my metadata?
- It is dropped. The image is redrawn from its pixels rather than repackaged, so EXIF, GPS, and C2PA data do not survive the conversion. That is usually what you want, but check first if you need the camera data.
- Why does my transparent PNG have a white background now?
- You converted it to JPG, which has no transparency. We fill transparent areas with white rather than black. Convert to PNG or WEBP to keep the transparency.
