    Sharing photos online: what image size and quality should you use?

    In this quick tutorial we’ll explain the best image size and quality for photographers who simply want to send email attachments or share photos online.

    We generally recommend shooting in raw mode for optimum quality, but it can be a pain if you end up having to convert many image files and reduce their size and quality settings for sending via email or sharing photos online.

    Another factor is that raw files quickly consume your camera’s memory cards, as well as eating into storage capacity.

    It can be a better solution to shoot in JPEG mode with a combination of smaller image sizes and greater compression ratios. Image quality may not be quite as good, but should still be sufficient for on-screen viewing.

    Here’s a quick guide of what’s available in most cameras, and the relative differences of the various options.

    What is the best file quality and size for sharing photos online: step 1

    1 Size
    The physical dimensions of images can be downsized to medium or small, with fewer megapixels. However, this reduces your options for subsequent cropping.

    2 Quality
    JPEG images can be captured with a trade-off between quality and compression. Images taken at a lower quality setting have a smaller data size and less impact on storage.

    3 Colour depth
    Some cameras offer 12- or 14-bit raw quality with different compression settings. Data size can be reduced, and the memory buffer can hold more shots in continuous shooting.

    4  Small raw
    In some cases, you can retain the flexibility of raw editing with physically smaller images, thanks to options for shooting in raw but with medium or small image sizes.
