How many files can I combine with OneFile?

There's no limit! Combine 10, 100, or even 1,000+ files into one. The only constraint is your browser's memory, which can typically handle thousands of files without issues.

Does this work with ChatGPT's free plan?

Yes! ChatGPT free users are limited to uploading 3 files per day. With OneFile, you can merge unlimited files into one text file and upload that single file to ChatGPT, bypassing the 3-file restriction entirely. Even Plus users benefit by avoiding the frustration of uploading files in batches of 10 for large projects.

Is my data private and secure?

Yes. Text and code files are processed entirely in your browser - they never leave your computer. Documents like PDFs and Word files are temporarily processed on our server for text extraction but are never stored. Our entire codebase is open-source on GitHub, so you can verify exactly how your files are handled.

Is OneFile really free?

Yes, completely free with no hidden costs, no account required, and no usage limits. OneFile is open-source software released under the MIT license.

How do I upload more than 3 files to ChatGPT?

Combine your files into one using OneFile (free tool), then upload the single combined file to ChatGPT. This bypasses the 3-file daily limit on Free plans.

Does this work with ChatGPT Free plan?

Yes! ChatGPT Free limits you to 3 files per day. OneFile lets you merge unlimited files into one, so you only use 1 of your 3 daily uploads while including all your content.

ChatGPT File Upload Limit? Upload Unlimited Files (Free Fix 2026)

Q: Can I upload an entire GitHub repository?

Yes! Use our GitHub import feature to browse and select files from any public repository. You can also download a repo as a ZIP, extract it, and upload the entire folder. OneFile automatically respects .gitignore files and skips node_modules, .git, and other unnecessary directories.

Q: What file types are supported?

OneFile supports 50+ file types including PDFs (.pdf), Microsoft Office files (.docx, .xlsx, .pptx), code files (.js, .py, .java, .cpp, .tsx, etc.), text files (.txt, .md, .csv), configuration files (.json, .yaml, .env), and many more. Images and binary files are automatically filtered out.

Say goodbye to hitting ChatGPT's file upload limit. Combine unlimited files into one and upload instantly. Free tool, no account, works on Free & Plus plans.

TL;DR

ChatGPT limits you to 3 files/day (Free) or ~80 files/3hrs (Plus). The fix: combine all your files into one text file before uploading.

Quick solution: Go to OneFile → Upload files/folders → Download combined file → Upload to ChatGPT. Free, no account needed.

If you've tried uploading multiple files to ChatGPT, you've hit the frustrating 3-file limit. Whether you're analyzing research papers, sharing code for review, or preparing meeting documents, this restriction kills productivity.

Here's how to bypass ChatGPT's file upload limit for free.

Understanding ChatGPT's File Upload Limits

ChatGPT Free Plan Limitations

Maximum 3 files per day: Can't upload more until the next day
512MB per file limit: Most files fit, but there's a daily cap
Limited file types: Common formats like PDF, DOCX, TXT, code files
No folder uploads: Each file must be selected individually

ChatGPT Plus Limitations ($20/month)

10 files per message: Must upload in batches for large projects
~80 files per 3-hour window: Rolling limit resets over time
512MB per file: Same size limit as Free
No folder or repository support: Can't upload entire projects at once

These limits exist to manage server costs, but they're a bottleneck for legitimate use cases like analyzing research papers, reviewing codebases, or processing multiple documents. For a complete breakdown of all plans including Pro, Team, and Enterprise, see our ChatGPT File Upload Limits 2025 guide.

The Solution: Combine Files Before Uploading

The workaround is simple: merge all your files into a single text file before uploading to ChatGPT. You upload one file, but ChatGPT gets access to hundreds of original files.

This works with all AI platforms: ChatGPT (Free and Plus), Claude, Gemini, and any AI that accepts file uploads.

How File Combining Works

Instead of: 3 separate files (limit reached) ❌

Upload: 1 combined file containing 100+ files ✅
├─ research_paper_1.pdf
├─ research_paper_2.pdf
├─ notes.txt
├─ data.csv
└─ 100+ more files...

Done! You've bypassed ChatGPT's 3-file limit. ChatGPT can now analyze all your files at once.

Real-World Use Cases

For Students

Analyzing 25+ research papers for a thesis? Upload the folder to OneFile, download the combined file, and ask ChatGPT to identify themes and research gaps.

For Developers

Need code review on a React project with 50+ files? Import your GitHub repository, download the combined file, and ask ChatGPT to review for bugs and security issues.

For Professionals

Preparing for a board meeting with quarterly reports? Combine all DOCX, PPTX, and XLSX files, then ask ChatGPT to summarize trends and identify risks.

Tips for Best Results

Structure Your Prompts

Give ChatGPT context about what you uploaded:

"I've uploaded a combined file with [number] files from my [project]. Please analyze and [specific request]."

Reference Specific Files

OneFile adds file path markers. Use them for targeted questions:

"Look at src/components/UserAuth.tsx and explain how authentication works."

Mind the Token Limits

ChatGPT has a ~128K token context window (~1-2MB of text). For large projects, remove unnecessary files or split into logical groups.

Remove Sensitive Data

Check for API keys or passwords before uploading. OneFile's .gitignore support automatically skips .env files.

Frequently Asked Questions

Yes. Plus users bypass both the 10-file per message limit and the ~80 files per 3-hour window limit. Upload unlimited content in one file.

Will this work with Claude or Gemini?

Yes. OneFile's output works with all AI platforms: Claude, Gemini, Grok, Perplexity, and any LLM.

Is my data private?

Yes. Text files are processed in your browser and never reach our servers. Complex documents (PDFs, DOCX) are sent to our API for extraction, then immediately deleted. OneFile is open source. Verify it yourself.

Can I upload an entire GitHub repository?

Yes. Sign in with GitHub and import any repository. OneFile respects .gitignore and skips node_modules, .git, and build artifacts. See our guide to importing GitHub to ChatGPT for free.

How large can the combined file be?

No limit in OneFile, but ChatGPT has a ~128K token context window. Keep combined files under 1-2MB for best results.

What file types are supported?

50+ file types:

Documents: PDF, DOCX, PPTX, XLSX, DOC, PPT, XLS, RTF, ODT
Code: JS, TS, JSX, TSX, PY, JAVA, GO, RS, RB, PHP, C, CPP, CS
Web: HTML, CSS, SCSS, JSON, XML, YAML, GraphQL
Data: CSV, TSV, SQL

Does this violate ChatGPT's Terms of Service?

No. You're uploading a single text file, which is allowed. The file just contains content from multiple sources.

Conclusion

ChatGPT's 3-file limit (Free) or 80-file rolling limit (Plus) doesn't have to slow you down. Combine your files into one before uploading, and you can work with unlimited content.

OneFile makes this effortless. It's free, open source, and takes seconds.
