What file types are supported? Are there any limitations?

Collage.com supports JPEG (JPG), GIF (not animated), and PNG images. If you have .BMP files, please read how to convert .BMP to .JPG; if you need to convert other file types, please reference this image conversion article.


The maximum image resolution that can be uploaded to Collage.com is 8000 × 8000 pixels. The maximum file size of an image is 10 Megabytes (MB). For a photo to successfully upload, it should be under both limits.

  • To find out whether your image meets these requirements, you can right click on the photo and click 'Properties' (on Windows) or 'Get Info' (on Mac OS X). When you do so, both the image resolution and file size should be listed.

For the best uploading results, you should upload in small batches of 5 images or less at a time. If you're emailing images to your account, the email cannot contain more than 20MB of data to upload successfully.
