Get Thumbnail Representation
Get Thumbnail Representation
A thumbnail is a small image, either as .png
or as .jpg
that can be used in
an application as a representation of the file, for example as a placeholder for
a link that downloads or previews the file.
All thumbnail representations except 1024x1024
and 2048x2048
PNGs are
generated upon uploading the source file to Box.
The process
To get a thumbnail representation follow the following steps
- List all representations
- Request a thumbnail by passing the
x-rep-hints
-header for the desired thumbnail format and size, for example[jpg?dimensions=32x32]
. - Download the thumbnail by calling the
url_template
, replacing the{+asset_path}
with an empty string.
A retry-after response header is also provided to present you with an estimated amount of seconds before retrying this endpoint.

File size restrictions
JPEG 2048x2048
The JPEG 2048x2048
size is only available when the
original file is a JPEG. We recommend either requesting a PNG or both a PNG
and a JPEG for this dimension.
Video files

, PNG 2048x20148
and PNG 1024x1024
