Question 1

Is it really 100% offline?

Accepted Answer

Yes. Once installed, 1FileTool processes every single file entirely on your computer. There are no server calls, no uploads, no cloud processing. Your files never leave your device, ever.

Question 2

What file formats are supported?

Accepted Answer

1FileTool supports 100+ file formats including PDF, JPG, PNG, WebP, SVG, GIF, MP4, MOV, AVI, MKV, MP3, WAV, FLAC, AAC, ZIP, CSV, XLSX, JSON, XML, HTML, Markdown, and many more.

Question 3

Is there a free version?

Accepted Answer

Yes. 1FileTool is free to use with all 265+ tools and up to 8 files per day. Upgrade to Pro for unlimited processing with a one-time payment starting at $29.

Question 4

How is this different from online tools like Smallpdf?

Accepted Answer

Online tools require uploading your files to their servers for processing. 1FileTool processes everything locally on your device, so your files never leave your computer. Plus, you pay once instead of monthly.

Question 5

Does it work on both Mac and Windows?

Accepted Answer

Yes. 1FileTool is available as a native application for both macOS (Apple Silicon and Intel) and Windows (64-bit) with identical functionality.

Question 6

Can an AI assistant use 1FileTool?

Accepted Answer

Yes. AI Access exposes 64 operations to Claude Code, Codex and Gemini over MCP. You ask for the work in plain language and your assistant sends instructions to the app on your machine — your files are never sent to the assistant.

Question 7

Does the AI run on my computer?

Accepted Answer

Yes. Background removal, read-aloud, audiobook conversion, voice cleanup and PII detection all run on your device after a one-time model download. There is no AI API key and no per-use cost.
