“The uploaded file exceeds the upload_max_filesize directive”

PHP limits the size of a single upload with upload_max_filesize, and the whole request with post_max_size. WordPress shows the effective limit in Media → Add New.

Option 1: raise the limit

Check whether these settings can be changed for your account, and raise both together — post_max_size must be at least as large as upload_max_filesize. Changing PHP settings: memory_limit, upload size and execution time

Option 2: upload another way

Big files don’t need to go through WordPress’s uploader.

• Themes and plugins: unzip on your computer and upload the folder into wp-content/themes or wp-content/plugins using the File Manager or SFTP. How to upload and extract a zip file
• Media: upload to wp-content/uploads via SFTP, then use a media-import plugin to register them in the library.

Option 3: make the file smaller

• Images straight from a camera are often 5–10MB. Resize to the largest size your site displays and compress them. How to optimise images for a faster website
• Video belongs on a video platform, embedded in the page. It uses your 3GB and bandwidth quickly otherwise.
