Perplexity file upload limits — supported formats, size limits, and weekly caps

Perplexity Pro supports file uploads up to 25 MB per file. Supported formats include PDF (text-based, not scanned), plain text (.txt), and Word documents (.doc and .docx). File upload is a Pro-only feature — free plan users do not have access. If your file exceeds the size limit or is in an unsupported format, compress it or convert it to PDF before uploading. Alternatively, paste the text content directly into the search bar, which works for most analysis tasks.

Perplexity Limit Exceeded: 3 Causes and How to Fix Each

Perplexity's 'limit exceeded' message has three distinct causes: (1) Pro search weekly quota of 200 searches exhausted — wait until Monday 00:00 UTC; (2) Deep Research monthly quota of 20 sessions used up — wait until the 1st of next month; (3) Free plan daily quota of ~5 Pro searches reached — wait until 00:00 UTC tonight. Switch to Standard search to continue immediately in all three cases.

How to avoid Perplexity temporary restrictions and suspicious activity flags

Perplexity temporary restrictions are triggered by 3 main behaviors: submitting more than 20 to 30 queries in a short period, repeatedly switching between VPN server locations during a session, or using browser automation scripts that mimic bot traffic. If you are flagged, stop all activity and wait 1 to 4 hours for the restriction to lift automatically. Do not attempt to bypass the block by creating a new account — this risks a permanent ban. For persistent restrictions, email support@perplexity.ai.

Perplexity Pro Message Limit – How to Fix

As of May 2026, Perplexity Pro includes 200 Pro searches per week (down from 600) and 20 Deep Research reports per month (down from 50); limits reset every Monday at 00:00 UTC. Standard searches are unlimited on all plans. When you hit the cap, switch to Standard mode or wait for Monday's reset — there is no way to purchase additional Pro searches mid-cycle.

Perplexity Rate Limit Exceeded: 3 Scenarios and How to Fix Each

Perplexity's 'rate limit exceeded' error has three causes: (1) sending requests too fast in the API — wait 60 seconds and retry with exponential backoff; (2) exhausting your weekly 200 Pro searches — switch to Standard mode or wait until Monday 00:00 UTC; (3) exceeding the API default of 50 requests per minute — slow your request rate to 1 request per 1.2 seconds. Each scenario has a different fix.

How to Reduce Perplexity Throttling and Avoid Temporary Limits

To avoid hitting Perplexity throttle limits, default to Standard mode for routine searches and reserve Pro mode for queries that genuinely need deeper web access. Pro users get 200 Pro searches per week (resets Monday 00:00 UTC), so spreading them across 5 days gives you a safe budget of 40 Pro searches per day. Use batch-style queries — combine multiple related questions into one well-structured prompt — to get more value from each Pro use.

Perplexity Upload Quota Exceeded: How to Continue Research Without Stopping

Perplexity Pro allows file uploads up to 50 MB per file, with a limit on total uploads per session or week. When your upload quota is exceeded, the fastest workarounds are: paste the text content of your document directly into the chat instead of uploading the file, split large documents into smaller chunks and upload them in separate sessions, or use URLs to share online documents rather than file uploads.

Perplexity Usage Limit Exceeded: Pro Search, Deep Research, and Free Tier Fixes

Perplexity has three separate usage limits depending on what you hit: Pro search quota (200 searches per week for Pro users, resets Monday 00:00 UTC), Deep Research quota (20 sessions per month for Pro users, resets on your billing date), and free tier Pro search (approximately 5 Pro searches per day, resets daily at midnight UTC). Standard searches on the free tier are unlimited. Identify which limit you hit, then follow the matching fix below.

Perplexity Usage Limits vs. Throttling: How to Diagnose and Fix Both

Perplexity has two distinct restriction mechanisms that are frequently confused: usage limits (your weekly Pro quota of 200 searches is fully depleted — only resets Monday 00:00 UTC) and throttling (too many requests sent in a short burst — clears in 60 to 120 seconds without any quota impact). Distinguishing them is the first step: if Standard mode still works but Pro is blocked, it is a usage limit. If all searches fail briefly then recover, it is temporary throttling.
