Perplexity Upload Limit: File Limits by Plan Explained (2026)

The Perplexity upload limit works differently than most people expect, because there are actually three separate limits stacked on top of each other: a per-file size cap, a per-prompt file count cap, and a daily or weekly usage cap that depends on your plan and which AI model you’re using.

Hitting one of these doesn’t mean you’ve hit all of them. Understanding which cap you’ve triggered changes how you work around it.

This guide covers exactly what each plan allows, what triggers each limit, and the fastest workarounds when you’re blocked mid-session.

What is the Perplexity upload limit?

Direct answer: The Perplexity upload limit is a set of file attachment restrictions that vary by plan. On the free plan, file uploads are restricted to images only and limited to a small number per day. On Pro ($20/month), you get unlimited daily file uploads overall but a cap of 10 files per single prompt. On Enterprise plans, the cap rises to 30 files per prompt and 100 per week for Enterprise Pro.

The per-prompt limit of 10 files is the one most Pro users hit first, since it applies regardless of daily total. You can upload 200 files in a day on Pro, but not more than 10 to a single thread at once.

Perplexity upload limits by plan

Plan	Files per prompt	File size limit	Daily/weekly cap	Images per query
Free	Limited	40 MB	Low daily cap	Up to 3
Pro ($20/month)	10 files	40 MB	Unlimited daily (standard models)	Up to 4
Enterprise Pro	30 files	50 MB	100 per week	Up to 4
Enterprise Max	30 files	50 MB	1,000 per week	Up to 4

Note on Pro limits as of mid-2026: Some Pro subscribers have reported hitting weekly limits on advanced models (Gemini 3.1 Pro, Claude 4) significantly faster than expected. Perplexity confirmed in May 2026 that enforcement has been tightened for promo code accounts. Limits for standard Pro accounts remain as published. If you’re hitting caps faster than the table above suggests, check whether your account was activated through a third-party promotional code.

How many images can you upload to Perplexity?

You can upload up to 4 images per query on Perplexity Pro. Free plan users can attach images but with a lower daily cap.

Images count toward your per-prompt file limit. If you attach 4 images and 6 documents in a single thread, you’ve hit the 10-file Pro cap. Images don’t get a separate allocation, they share the same pool as document uploads.

Supported image formats include PNG, JPEG, GIF, and WebP. Each image must be under 40 MB on Pro (50 MB on Enterprise plans).

What file types does Perplexity support?

Perplexity supports a wide range of file formats across plans:

Documents: PDF, DOCX, XLSX, CSV, PPTX, TXT, Markdown, JSON

Images: PNG, JPEG, GIF, WebP

Code files: Most standard code file types are supported on Pro and above

Audio and video: Supported in the consumer app on Pro, audio and video are transcribed into searchable text, though video scenes are not visually analyzed

Not supported for image uploads in knowledge search: PNG and JPEG are only available as direct attachments in Threads, not in internal knowledge search on Enterprise plans

What happens to uploaded files after a session?

Files uploaded to Threads are retained for 7 days and then automatically deleted. Upload a document to a Thread and it’s gone after a week unless you save the content yourself.

For Pro users who need persistent file access, Spaces are the solution. Files added to a Space remain available until explicitly deleted. Pro plan users can store up to 50 files in a Space, while Enterprise Pro users can store up to 500.

This distinction matters for workflows. For ongoing analysis of the same documents, upload to a Space rather than a Thread. Files in Spaces persist beyond the 7-day window.

Why you might be hitting the limit sooner than expected

Advanced model queries count more heavily. The daily and weekly caps on Pro apply more strictly to queries using advanced models like Gemini 3.1 Pro or Claude 4 within Perplexity’s interface. Queries using Perplexity’s standard Sonar models are less restrictive. If you’re consistently choosing an advanced model, you’ll hit limits faster than the published caps suggest.

Promotional code accounts have different limits. Accounts activated through third-party promotional codes may have tighter enforcement applied to them. If your subscription came through a third-party reseller rather than directly through perplexity.ai, your effective limits may differ from standard Pro accounts.

Multiple uploads in one session add up. The per-prompt cap is 10 files. But daily totals accumulate across all prompts in a session, even if each individual prompt stays under 10 files.

How to work around Perplexity upload limits

Merge multiple files into one before uploading. If you need to analyze more than 10 documents at once, combine them into a single PDF before uploading. Free PDF merger tools (Smallpdf, IlovePDF) handle this in a few clicks. One merged PDF counts as one file against your limit. This is the most practical workaround for the per-prompt cap and doesn’t require any plan upgrade.

Use Spaces for persistent, repeated access. If you’re repeatedly analyzing the same files, add them to a Space once. Don’t re-upload them to every new Thread. This avoids counting the same documents against your daily cap repeatedly.

Switch to a standard model for bulk analysis. If you’re hitting advanced model caps, switch to Perplexity’s Sonar model for file-heavy sessions. The analysis quality difference is smaller than people expect for document summarization tasks, and the limits are more generous.

Split large analysis sessions into multiple threads. If you need to analyze 25 documents on Pro, split them across three threads rather than pushing everything into one.

Perplexity upload limit vs other AI tools

For context on where Perplexity sits among AI file upload limits in 2026:

• ChatGPT Plus: approximately 80 files per 3-hour rolling window, up to 512 MB per file
• Claude Pro: approximately 20 files per conversation, up to 30 MB per file, 200,000 token context window
• Perplexity Pro: 10 files per prompt, unlimited daily total, 40 MB per file
• Gemini Advanced: 10 files per prompt, 100 MB per file, no reported daily cap

Perplexity’s per-prompt cap (10 files) is at the lower end, but its unlimited daily total for standard model queries is genuinely generous compared to the rolling windows other platforms use. The real Perplexity differentiator isn’t file volume. It’s that uploads combine with live web search in the same query, so you can analyze a document and cross-reference it against current web sources at the same time.

Frequently asked questions

What is the Perplexity daily file upload limit?

On Pro, daily file uploads are unlimited for queries using standard Sonar models, with a cap of 10 files per individual prompt. For advanced model queries (Gemini 3.1 Pro, Claude 4 within Perplexity), daily limits apply and vary by account type. Free plan users have a lower daily cap across all model types.

How many images can I upload to Perplexity at once?

Up to 4 images per query on Pro and Enterprise plans. Images share the same per-prompt file pool as documents, so attaching 4 images uses 4 of your 10 available file slots per prompt on Pro.

Why am I hitting my Perplexity upload limit faster than expected?

Two common reasons. First, you’re using an advanced model (Gemini 3.1 Pro or Claude 4 within Perplexity), which has tighter limits than standard Sonar models. Second, your account was activated through a promotional code with different enforcement. Check your account type at perplexity.ai and switch to standard Sonar models for file-heavy sessions.

Do uploaded files stay in Perplexity permanently?

No. Files uploaded directly to Threads are deleted after 7 days. Files uploaded to Spaces (Pro feature) persist until manually deleted. For files you need across sessions, use Spaces rather than Thread uploads.

How do I upload more than 10 files to Perplexity at once?

Merge the files into a single PDF before uploading using a free tool like Smallpdf or IlovePDF. One merged file counts as one against your per-prompt cap. So you can effectively analyze far more than 10 documents in a single query.

Is the Perplexity Pro upload limit worth it compared to the free plan?

Yes, for regular file analysis work. The free plan’s upload restrictions make it impractical for document-heavy workflows. Pro’s 10-files-per-prompt cap with unlimited daily total covers most individual research use cases without needing an Enterprise upgrade.
