If Vinci won't let you attach a file, it's almost certainly hitting one of two limits. Here's what they are and what to do.
File size limit
Each file you attach must be 8 MB or smaller. If your file is larger, you need to split it or trim it down:
- For documents: if it's a large PDF, try splitting it in half and attaching each part in separate messages.
- For images or media: compress them before uploading. Most image tools let you reduce resolution or quality to shrink the file size.
- For code files: if a single file is too large, paste just the relevant section into the message instead of attaching it.
File count limit
You can attach up to 5 files per message. If you need to send more, split them across multiple messages.
Very image-heavy PDFs
If you're attaching a PDF that's mostly images (like a scanned book), Vinci might not read all the content correctly. If that happens, copy the relevant text directly into your message instead of uploading the file — it usually works better.
Files are never stored
Whatever you attach is processed in the moment and then deleted — Vinci doesn't keep files on our servers. See Using the app for details on what file types work best.
Still having trouble?
If the file is under 8 MB, you have 5 or fewer files, and the upload still fails, contact support with the file type and size you're trying to attach.
