Supported File Types and Size Limits for Chat Attachments
Quick reference
SoulrisAI's chat accepts the following attachment types:
- Images: JPEG, PNG, WebP
- Documents: PDF, plain text (.txt)
These cover both image analysis and document upload — the AI treats them differently depending on type (looking at an image vs. reading a document's text), but both are attached the same way, from the same control in the chat interface.
File types that aren't supported
Formats outside the list above — Word documents, spreadsheets, PowerPoint files, HEIC images (common on some phones), audio, and video — aren't accepted as chat attachments directly. The practical workaround for most of these is to export or convert to a supported format first: save a Word document or spreadsheet as a PDF, or convert a HEIC photo to JPEG, before attaching it.
Size and length limits
There are practical limits on both file size and, for documents, how many pages can be processed in one attachment. If a file is too large or a document too long, SoulrisAI tells you clearly rather than failing silently or accepting a corrupted-looking attachment — you'll see a message explaining what the issue is.
How many attachments per message?
There's a cap on how many files you can attach to a single message. If you need the AI to consider multiple documents or images together, check that you're within the per-message limit; if you have more than that, you may need to send them across a couple of messages in the same conversation rather than all at once, since the AI retains earlier attachments within the thread (see how conversation memory works).
Why attachments aren't on the free tier
All attachment types — images and documents alike — require a funded wallet. There's no free-tier allowance for this feature. See why attachments need a deposit for the reasoning.
What to do if your file is rejected
If an attachment doesn't go through, check first whether it's an unsupported format or likely over the size/length limit — both are the most common causes. Converting to PDF (for documents) or JPEG/PNG (for images) resolves the large majority of rejected uploads. If you've checked both and it's still not working, that's worth reporting — see our contact page.
