Meta AI file uploading is a multifaceted feature, with support, limits, and rules that vary based on where Meta AI is accessed—whether on the Meta AI app, Meta.ai web, WhatsApp, Messenger, or Instagram messaging. Users can upload media and documents for question answering, editing, and animation, but practical constraints depend on the hosting product and regional rollout.

File Upload Support In Meta AI Varies By Product Surface And Use Case.
Meta AI enables users to attach files or media when asking questions, editing, or animating content. The main surfaces for file uploading are the Meta AI app, the Meta.ai website, and Meta’s messaging apps—WhatsApp, Messenger, and Instagram.
In the Meta AI app and on Meta.ai, users see “Add media or files” options for submitting images, documents, or videos, and specific “Upload” flows are offered for editing or animating media. Meta has announced ongoing tests for document import and document-based analysis, but the rollout may vary by country and account.
On WhatsApp and Messenger, users can upload documents and media into chats with Meta AI, leveraging the native attachment features of each platform. Instagram messaging also supports file attachments, including PDFs, with file-type and size limits defined by the messaging product.

Attachment And File Type Support Across Meta AI Surfaces
Surface | Supported Upload Types | Notes |
Meta AI app / Meta.ai | Images, videos, documents | Document import in testing, region-dependent |
Documents, images, videos | Meta AI access via mention or explicit share | |
Messenger | Office documents, images, videos | Uses Messenger’s attachment rules |
Instagram messaging | PDFs, images, media | Messaging caps apply |
Supported formats and features may differ based on product and rollout status.

Maximum File Size Limits Are Defined By The Hosting Product’s Attachment Rules.
Meta AI does not publish a single, universal per-file size limit for all surfaces. Instead, the file size constraint is determined by the specific app or messaging platform being used to access Meta AI.
WhatsApp allows document uploads up to 2 GB. Messenger supports file uploads up to 100 MB. Instagram messaging permits PDF uploads up to 25 MB, with other media types having their own size caps. The Meta AI app and Meta.ai web do not list a strict universal cap, as file size rules may change depending on country, account cohort, and rollout phase.
These attachment rules dictate what files can be shared, analyzed, or edited through Meta AI, especially when accessed within messaging apps.
........
Meta AI File Size Limits By Platform
Surface | Maximum File Size | Notes |
2 GB per file | Applies to documents and media | |
Messenger | 100 MB per file | All attachments |
Instagram messaging | 25 MB per PDF | File-type specific limits |
Meta AI app / Meta.ai | Not universally published | Region/account dependent |
Users should consult app-specific limits before uploading large files.
·····
Upload Rules And Content Access Are Controlled By Sharing And Mention Mechanisms.
Meta AI respects privacy and message boundaries by only accessing content that users explicitly share or attach in a Meta AI conversation. On WhatsApp, Meta AI can only access files and messages when it is mentioned with @Meta AI or when content is directly shared with Meta AI in a chat.
Other messaging surfaces, such as Messenger and Instagram, use their attachment and sharing flows to define which files are available to Meta AI. The AI system does not automatically scan all chat content—only content intentionally provided by the user is analyzed or processed.
In the Meta AI app and Meta.ai, uploads are tied to specific question, editing, or animation workflows, with availability and feature set varying based on region and account type.

Meta AI Upload Rules And Content Access
Rule | Description | Platform Notes |
Explicit sharing | Only files or messages shared or mentioned are accessible | All platforms |
Mention trigger | @Meta AI is required for access in WhatsApp | WhatsApp-specific |
Upload entry points | “Add media or files” or “Upload” flows used | Meta AI app, Meta.ai |
No universal scan | AI does not access all chats by default | Privacy-by-design |
File access always depends on user action.

Document Reading Features Include Q&A, Media Understanding, And Editing Workflows.
Meta AI’s document reading is primarily focused on answering questions about attached files or media, as well as supporting editing and animation for uploaded images and videos. In the Meta AI app and Meta.ai, users can ask questions about uploaded content or use dedicated editing tools.
Document import and analysis are currently described as a test feature, so the ability to analyze office documents or export generated content as PDF may only be available in certain regions or for selected users. Messaging app uploads focus more on sending and retrieving attachments, with document reading limited to what the product surface supports.
The range of supported document types, reading depth, and editing tools may expand as Meta AI continues to evolve and roll out new capabilities.

Meta AI File Uploading Depends On Product, Region, And Attachment Rules.
Meta AI’s file uploading and document reading capabilities are shaped by the product surface, attachment limits, sharing mechanisms, and ongoing feature tests. Users should consider the specific messaging or Meta AI platform they use, along with its file type and size rules, for a reliable and privacy-aware experience.
