If Apsona displays an error such as "Template file too large... at most 2,000,000 allowed," the .docx template has exceeded Apsona's maximum supported template size of 2,000,000 bytes (approximately 2 MB).
Word templates can become unnecessarily large due to embedded fonts, images, and other rich content. To reduce the file size:
Disable "Embed fonts in the file" in Microsoft Word if it is not required.
Compress or remove unnecessary embedded images.
Remove unnecessary content or formatting from the template.
Consider using dynamic Salesforce images where appropriate.
In the reported case, disabling "Embed fonts in the file" reduced the template size sufficiently for it to upload successfully.
When troubleshooting template size errors, always check the .docx file size and remove unnecessary embedded content before attempting the upload again.
