When you upload files to a Perplexity Space, you may run into limits on file size and the number of files you can add. Perplexity restricts these to maintain performance and storage capacity. This article explains the exact upload limits for size and count, how these limits differ between Free and Pro accounts, and what happens when you exceed them.
Knowing the limits helps you plan your research projects without interruptions. You can use multiple smaller files instead of one large file to stay within the size cap. For projects requiring many files, you may need to organize them into separate Spaces.
This guide covers the default limits, how to check your current usage, and workarounds for common file upload issues.
Key Takeaways: Perplexity Space File Upload Limits
- Maximum file size per upload: 25 MB for Free accounts, 100 MB for Pro accounts.
- Maximum number of files per Space: 500 files for Free accounts, 2000 files for Pro accounts.
- Total storage per Space: 1 GB for Free accounts, 5 GB for Pro accounts.
Perplexity Space File Upload Limits Explained
Perplexity Spaces allow you to upload documents, PDFs, images, and other file types to provide context for your searches. The platform imposes three types of limits to manage resources: per-file size, per-Space file count, and per-Space total storage.
These limits apply to all file types, including PDF, DOCX, TXT, CSV, PNG, JPG, and others. Files are processed for search indexing, so large or numerous files consume server resources. The limits are designed to ensure fast processing and reliable search results.
The limits differ based on your account tier. Free accounts have lower caps, while Pro subscribers get higher allowances. If you exceed any limit, Perplexity will reject the upload and show an error message.
Per-File Size Limit
Each file you upload must be under the size cap. For Free accounts, the maximum file size is 25 MB. For Pro accounts, the limit is 100 MB. If a file exceeds this size, the upload fails immediately. You can split a large file into smaller parts and upload them separately, but each part must still be under the size limit.
Per-Space File Count Limit
Each Space can hold a maximum number of files. Free accounts are limited to 500 files per Space. Pro accounts can store up to 2000 files per Space. This count includes all file types, not just documents. Once you reach the limit, you cannot add more files until you remove some.
Per-Space Total Storage Limit
The total size of all files in a single Space cannot exceed a certain amount. Free accounts have a 1 GB total storage limit per Space. Pro accounts have a 5 GB limit. If the combined size of your files reaches this cap, further uploads are blocked until you delete files to free space.
Steps to Check Current File Usage in a Space
You can view your current usage for a specific Space to see how close you are to the limits. Follow these steps.
- Open the Perplexity Space
Log in to your Perplexity account and navigate to the Space you want to check. Click on the Space name from the left sidebar. - Access the Space settings
Click the three-dot menu icon next to the Space name at the top of the page. Select Settings from the dropdown menu. - View storage information
In the Settings panel, look for the Storage or Files section. You will see the number of files uploaded and the total storage used, along with the limits for your account tier.
If you are close to a limit, consider removing unused files or upgrading to Pro for higher caps.
Common File Upload Issues and Their Causes
File Too Large Error When Uploading a PDF
This error occurs when the file exceeds the per-file size limit for your account. For Free users, the limit is 25 MB. For Pro users, it is 100 MB. The solution is to compress the file or split it into smaller parts. Use a PDF compression tool or divide the document into chapters.
Cannot Add More Files to a Space
If you see a message that the Space is full, you have reached the file count limit or total storage limit. For Free accounts, the file count limit is 500 files and total storage is 1 GB. For Pro accounts, the limits are 2000 files and 5 GB. Delete unneeded files or create a new Space to continue uploading.
Upload Fails Without an Error Message
Sometimes the upload fails silently due to network issues or unsupported file formats. Check that your file is in a supported format: PDF, DOCX, TXT, CSV, PNG, JPG, or others listed in Perplexity documentation. Also ensure your internet connection is stable. Try uploading a smaller file first to test connectivity.
Perplexity Free vs Pro: File Upload Limits
| Item | Free Account | Pro Account |
|---|---|---|
| Maximum file size per upload | 25 MB | 100 MB |
| Maximum files per Space | 500 | 2000 |
| Total storage per Space | 1 GB | 5 GB |
| Supported file types | PDF, DOCX, TXT, CSV, PNG, JPG, and more | Same as Free |
These limits apply to each Space independently. If you create multiple Spaces, each one has its own file count and storage caps.
Pro accounts also get priority processing, which means files upload faster and searches return results more quickly. If you frequently work with large or numerous files, upgrading to Pro reduces friction.
Conclusion
You now know the exact file upload limits for Perplexity Spaces: 25 MB per file and 500 files per Space for Free accounts, and 100 MB per file and 2000 files per Space for Pro accounts. Total storage per Space is 1 GB for Free and 5 GB for Pro.
To avoid upload failures, check your current usage in Space settings before adding new files. If you hit a limit, delete old files or upgrade to Pro for higher caps. For very large projects, consider splitting content across multiple Spaces to stay within per-Space limits.
