Accepted file types for uploading

  • Updated

You can add an unlimited number of JPEG, GIF, PNG, and HEIC files to your SmugMug account.

Note: RAW files can be uploaded with a current SmugMug Source subscription.

The size limitations per photo are 500 mebibytes (a bit over 500 megabytes) and 4 gigapixels. RAW files have a limit of 3GB per photo.

If a file exceeds those limits, we'll try to resample it (in the case of too many pixels) or recompress it (in the case of large file size) to bring it within the limits. If we can't, you'll see an error in your upload log.

Although we support PNG files, they have limited browser compatibility and can't be used for prints through SmugMug. We recommend using them only for building your own themes (non-seller accounts) and custom watermarking (seller accounts).  

HEIC files also have limited browser compatibility, so we convert them to JPEGs to allow browsers to be able to display them. We don't retain a copy of the original HEIC file, so if you try to download the original at a later date, you'll receive a high-quality JPEG instead.

At this time we're unable to support LivePhotos and slow-mo movies, so the moving portion of LivePhotos will be ignored and a static JPEG will instead be displayed. Slow-mo movies will play in real time.

FYI: Only JPEGs can be ordered as prints and gifts.

Check out these additional tips for preparing your files for upload.

Where do I find my file's type?

On a Mac, hold down the command key and "i" keys on your keyboard. Or right-click on a file and select Get Info from the menu.

You'll be able to see the file size, file type, and image dimensions.


Each video file can be up to 20 minutes long and 3 GB in size. More details on supported video files are available in this article.

Does colorspace matter?

To help web browsers better display your photos the way you intend, make sure you embed the color profile in each image.
