Observed behavior
The file upload fails and displays a generic error message, likely timing out due to excessive file size or platform service limitations.

Solution 1Recommended

Compress the Large File Before Uploading

Reducing the file size prevents the upload process from timing out and helps bypass service size limits.

Large design files like Adobe Illustrator (.ai) documents can easily exceed the bandwidth or maximum file size thresholds of online sharing services. Compressing them into a ZIP archive is the most effective way to ensure a successful transfer.

1
Locate the file

Navigate to the folder containing your large 413 MB Adobe Illustrator file on your local computer.

2
Compress the file

Right-click the file, select 'Send to' and then click 'Compressed (zipped) folder' on Windows. On a Mac, right-click and select 'Compress'.

3
Split the archive (if necessary)

If the compressed file is still too large, use a tool like WinRAR or 7-Zip to right-click the file, select 'Add to archive...', and choose the 'Split to volumes' option to divide it into smaller pieces.

4
Retry the upload

Open Adobe Send, click the 'Select Files to Send' button, and choose the newly created, smaller ZIP file or split archives.

Frequently Asked Questions

Why does Adobe Send time out when uploading large files?

Adobe Send uploads typically time out if the file size is excessively large (like a 400MB+ document) and the internet connection is not fast enough to complete the transfer before the server drops the connection. Service limitations can also trigger generic upload errors.

What is the maximum file size limit for Adobe Send?

Depending on your specific subscription and the service version you are using, individual file uploads are often capped between 100 MB and 2 GB. If your file exceeds your account's tier limit, the upload will fail.

How can I share a 400MB+ file without using Adobe Send?

You can compress the file into a ZIP archive, use cloud storage platforms like WPS Cloud, Google Drive, or Dropbox, or utilize dedicated large-file transfer services like WeTransfer which are optimized for gigabyte-sized files.
