How to convert large DOCX files

Large DOCX files often fail for predictable reasons: too many images, oversized screenshots, embedded objects, or a document that is already near the 60 MB upload limit.

The easiest fix is to reduce the file before conversion. Compress images, remove unused pages, and save a clean copy of the final document so the upload stays under the limit instead of failing at the end of the process.

Try this workflow if your file is big:

• Check the file size before uploading.
• Compress images inside Word if possible, especially screenshots and photos.
• Remove hidden draft pages, duplicate graphics, or pasted content you no longer need.
• Split very long documents into smaller sections when one upload is not practical.
• Convert the final DOCX once, instead of repeatedly retrying drafts that are still changing.

If you are working with files near 60 MB, these small changes can make the conversion much more reliable and save time compared with repeated failed uploads.
