Limits

Every limit here reports itself rather than failing silently. These are the numbers to plan around.


#Every limit

Limit

Value

What happens

Upload. Drag and drop accepted extensions.

Bmp, gif, ico, jfif, jpeg, jpg, png, svg

Anything else raises 'Invalid file type. Only image files are allowed'.

Upload. Upload button file dialog filter.

.png .jpg .jpeg .gif .bmp .tiff .webp .p

This list omits svg, ico and jfif, which drag-and-drop does accept.

Thumbnail longest side

512 px

Generated previews are capped so a tile never decodes a full-resolution bitmap.

Thumbnail byte budget

0.25 MB

A file already inside both the dimension and byte budgets is used as-is. GIF and SVG are never re-encoded. A canvas round-trip would lose GIF frames and blur vector art. So their preview is the original file.

Stored asset title length

50 characters

The filename is truncated when building the stored title.

Stored asset description length

250 characters

An Unsplash caption plus author credit can be cut mid-sentence.

Editor / attachment-import fetch ceiling

3 MB

An attachment loaded for editing or importing into the library is capped at 3 MB of raw bytes. Larger files are auto-resized to PNG to fit; only if that still fails does it error 'Image too large for editor (N MB). Max 3MB.'.

Image edit re-encode threshold

Over 3 MB, recompressed to a 2.5 MB targ

Applied to an edited image before it is attached.

Rovo / chat attachment ceiling

5 MB

Refused above that with '<file> is N MB, above the 5 MB limit for an image these tools can read. Resize it and attach it again.'.

Rovo / chat accepted extensions

.png .jpg .jpeg .gif .webp .svg .bmp .av

PDF, AI and PSD are deliberately excluded even though the library uploader stores them. The check sniffs the file's bytes rather than trusting the filename.

Rovo / chat inline preview cap

64 KB of encoded data (roughly a 48 KB i

Above that, no inline preview is returned.

'Used on Pages' result cap

25 pages fetched, 5 revealed at a time

Beyond that the panel prints 'Showing X of N pages' with no way to page further.

Gallery page size

25 images per page

A 'Show more' button loads the next 25 while more remain.

Gallery live-tail window

24 hours

The folder listing tops up the search index with a live read of the folder's newest children, but only for items created in the last 24 hours. Outside that window the gallery shows exactly what the index shows.

Gallery responsive minimum column width

200 px

-

Gallery default tile height

188 px when Thumbnail Height is unset

-

Table layout preview size

Fixed 56 px, not configurable

-

PDF/Word export default width

760 px when the Image reference macro ha

-

Customer egress domain cap

10 domains in one fixed allowlist group

-

Attached images sweep. Accepted file extensi

Jpg, jpeg, png, gif, bmp, svg, webp, tif

AVIF, HEIC, ICO and JFIF attachments never appear. The sweep also excludes the CAPABLEASSETSTORE space, generated thumbnail files, and Capable's own library images.

Unsplash search debounce and failure ceiling

500 ms debounce; gives up after 5 consec

Search does not go to Unsplash from the browser. It calls Capable's own API with the viewer's app token.

Folder nesting

One flat level. No sub-folders.

A folder is always created with the space as its container, so there is no parent-folder field to populate.

Browser-side upload size guard

None

Nothing in the upload path enforces a maximum file size. Only the thumbnail is bounded, and the general compressor merely targets 5 MB and returns the original on failure. The hard 5 MB and 3 MB limits live on the server read paths, so an over-large file can b


#A few things worth knowing

  • A limit that is reached is reported in the interface, not in a log you have to find.

  • Limits are per site or per tenant depending on the limit. The table says which.

  • Edition can change some of these.
