Choose the kind of result you need. Each category brings related utilities together.
ToolMyth Video Studio is a browser-based editor for arranging video, audio, captions and visual elements.
PDF & Document Tools
Combine several PDFs into one document, split out selected pages, compress a large file or add a watermark before sharing.
Image & Media Tools
Resize an image to fit a form, convert its format, trim an audio clip or cut a video. Large media files may take more time and browser memory.
Calculators
Work out a percentage, calculate age or BMI, or compare loan payments and investment projections using your own inputs and assumptions.
Developer Tools
Format and validate JSON, turn JSON into CSV, encode Base64 or inspect JWT claims. Decoding a JWT does not verify its signature.
Business Tools
Compare profit, margin and markup to understand pricing, or generate a downloadable QR code for a URL or contact details.
Productivity Tools
Count words, clean up text, compare dates, calculate working days or estimate the cost of a trip without setting up a spreadsheet.
Built for everyday work
Why use ToolMyth?
For a small, specific task, a dedicated utility can save the setup of a larger application. Find a tool, work with your inputs and return when you need it again.
Browser-first tools
Many utilities calculate or process files directly in your browser. Check each tool's description and FAQ for processing details.
No unnecessary account
Start using the available utilities without registering. Favorites and recent tools help you return to tasks in the same browser.
Simple and focused
Each tool handles a specific job, with inputs and results kept together so you can adjust settings and try again.
Multiple categories
Move between documents, media, development, business and everyday calculations using the same search and category navigation.
How ToolMyth works
Choose a tool
Search for your task or browse a category. Read the tool description to check that it supports the result you need.
Enter data or select a file
Provide the inputs the tool needs, then choose any relevant settings. Check file types, size limits and processing notes before starting.
Get the result
Calculate, convert or generate your output. Review the result, then copy or download it where the tool provides that option.
Built with privacy in mind
Many ToolMyth tools use browser-side processing, reducing the need to send files to a remote processing server. For example, PDF Merge combines selected documents in your browser, and JSON Formatter uses your browser's JSON parser.
Processing methods vary. Multiplayer rooms connect to a server to share room activity, and browser-side processing does not mean the entire website makes no network requests. Check the individual tool's description and FAQ before working with sensitive information.

Frequently asked questions
What is ToolMyth?
ToolMyth is a collection of online utilities for documents, images, audio, video, development, calculations and everyday tasks. Search for a specific job or browse a category to find a tool and its instructions.
Do I need an account to use ToolMyth?
You do not need an account to use the available utilities. Favorites and recently used tools are saved in this browser, so they do not automatically follow you to another device. Multiplayer tools may ask for a display name and room code.
Are ToolMyth tools free?
The available tools are free to use. Some catalog entries are marked as not yet available; those entries do not provide a working tool. Individual tools may have limits on file types, file sizes or supported operations.
Are uploaded files stored?
Processing varies by tool. Browser-based utilities such as PDF Merge read selected files locally for processing, rather than uploading them to a processing server. Services that connect to a server can behave differently. Read the relevant tool's description and FAQ before providing sensitive data; selecting a file alone does not tell you where it will be processed or stored.
Can I use ToolMyth on mobile devices?
Yes, you can browse and use tools in a mobile browser. Available features depend on your browser and device. Large PDFs, audio or video files can need substantial memory and processing time, so a desktop may be more practical for those tasks.
