You need to upload several supporting documents if you are preparing for an online application for immigration through IRCC. Here, we will explain to you the acceptable file formats and size. This guide will be applicable for all temporary permits as well as permanent entry permits.
The IRCC accepts the files in .pdf, .tiff, .jpg, .png, .doc, and .docx formats. Any files in formats apart from these will not be accepted by the system for upload. You can combine multiple pages into a single file in the required format for easier conversion.
The file size for online upload is less than or equal to 4MB. If you have images in high resolution, you need to convert them to lower resolutions. IRCC will often expect you to bundle multiple documents together into a single file rather than uploading separate multiple documents.
To avoid problems while uploading files, be sure to prepare your application files in advance. With this you can deal with unexpected issues in time, if any.
