Attaching files to a chat
Written By Paolo Rufrano

The paperclip button in the chat box, Add files & photos, attaches documents and images to a message.
What you can attach
Limits: up to 2 files per message, 5 MB each.
Attaching files isn't restricted by plan. Free accounts can do it too.
Why images are sometimes rejected
Not every model can see. If the model you've selected is text-only, image files are refused and you'll see:
File type not supported. Please upload PNG, JPEG, WebP images or PDF files.
The fix is to switch model. In the model picker, look for the small image icon on a model card (Upload images), or filter under Accepts (Input) → Images. See Choosing a model.
PDFs work on any model, because they're read as text before the model sees them.
The other messages you might see
File size exceeds 5 MB limit.
Compress the file or split it. For a long PDF, consider putting it in a project instead. Project files are indexed and searched rather than sent whole, which handles much larger documents. See Projects: instructions, files and memory.
Only a maximum of 2 files allowed.
Send them across two messages, or use a project.
How PDFs are read
PDFs are processed with text recognition before the model sees them, so scanned documents and images of text work, not just PDFs with a text layer. Percy Chat compresses the file on your device before uploading, which helps larger documents fit under the 5 MB cap.
Reading a PDF costs credits, as part of what the message costs. Long documents cost more.
In the conversation
Attached images appear inside your message and open full-size in a new tab when clicked. PDFs appear as a row with a PDF tag. Before sending, each attachment has a Remove file button if you change your mind.
Managing files you've uploaded
Go to Settings → File Attachments for everything you've ever attached, with file name, type, size and upload date. Each row has:
