The file size exceeds the limitation set for your server

Hello @Jackson

To increase that value first locate and open /etc/onlyoffice/documentserver/default.json config, then find "inputLimits" section and change the value for presentation extensions in "uncompressed" string:

			"inputLimits": [
                ...
				{
				"type": "pptx;ppsx;potx;pptm;ppsm;potm",
				"zip": {
					"uncompressed": "50MB",
					"template": "*.xml"

Here value is defined in megabytes.

Then restart Document Server services with:

  • supervisorctl restart all for Docker installation;

In case you are running Document Server in Docker container please locate and change the config inside the container.

  • systemctl restart ds-* for DEB/RPM packages installation from version 7.3.

In addition, you can increase the general file size that Document Server can handle:

	"FileConverter": {
		"converter": {
			"maxDownloadBytes": 104857600,

This value is defined in bytes.

After that re-upload your presentation to the storage (I’d recommend also changing a name of the file slightly) and try to open it again.
