Frequently Asked Questions

What is the exact file size limit for Acrobat Online?

Acrobat Online strictly restricts individual file uploads to a maximum of 100 MB. Any file exceeding this size will trigger an upload error.

Can I increase the Acrobat Online upload limit without paying?

No, the 100 MB limit is a hard restriction for the free Acrobat Online service. To process larger files, you must either use an alternative offline desktop application or compress the file below 100 MB.

Why does my 1.3 GB PDF crash my browser when uploading?

Web browsers have memory constraints and struggle to process gigabyte-sized files. Attempting to upload a 1.3 GB document overloads the browser tab, leading to crashes or timeouts alongside the platform's size restrictions.

How can I reduce the size of a 1.3 GB PDF?

You can use desktop PDF software with a 'Compress' or 'Reduce File Size' feature. Keep in mind that for a file this large, compression may lower image resolution significantly, and it still might not reach the 100 MB threshold.
