About "AI Toolbox"
Features
AI Toolbox is a collection of 15+ online tools for handling video, images, audio, and documents—completely free and with no account required. Its defining feature is that all processing runs entirely in your browser (via WebAssembly), so files are never sent to any server. No upload is needed and no network communication occurs, so you can safely work even with sensitive material.

How to use
-
Open a tool
Go to AI Toolbox and pick the tool you want (e.g., Video Splitter). No account or login is required.
-
Load your file
Select the file you want to process. Nothing is uploaded—the file is loaded inside your browser.
-
Configure and run
Specify options such as split points, output format, or crop ratio, then run it. All processing happens on your device (WebAssembly).
-
Save the result
Download the generated file. The original never remains on any server.
Pricing
Completely free, with none of the following limits:
- Cost / paywall: none (all features are free)
- Account / login: not required
- Usage count / file-size limit: none
Because nothing is processed server-side, there is no metered billing or credit consumption, and you can handle files of any size for free.
Privacy & security
AI Toolbox's biggest differentiator is a design where your data never leaves your device.
- All processing runs in a WebAssembly engine inside the browser tab, with zero network communication.
- Since files are never uploaded to a server, you can safely handle confidential material such as internal videos, contract PDFs, and unreleased images or audio.
- It uses no analytics cookies, and its source code is public, so anyone can verify how it works.
This structurally avoids the common concern with cloud-based converters that "uploaded files are stored on a server or passed to third parties."
Pros & cons
Pros
- In-browser processing keeps files off external servers—strong on privacy and security
- Completely free, no sign-up, no limits—ready to use the moment you need it
- Standard video, audio, image, and document tasks in one place
- No installation required, with support for 8 languages including Japanese
Cons
- Because processing happens on your device, very large files or low-spec devices may take longer
- It centers on conversion, editing, and formatting rather than generative AI (video/image generation)
- It lacks the advanced video-editing features of dedicated software, such as timeline editing and effects
Who it's for
- Video creators and marketers who want to clip part of a video or convert its format
- Production, legal, and IT staff who value confidentiality and don't want to upload material to a server
- General users who want to quickly do one-off conversions, compression, or merging without installing software
