Documentation Center • Last updated: August 19, 2026
Learn what our tools do, how they work, what files and inputs they support, what limitations may apply, and how to choose the appropriate tool for common tasks.
atoolix provides browser-based utilities for common PDF, image, file, signature, passport-photo, date-and-time, QR-code, mathematical, and financial calculation tasks.
The purpose of this documentation is to explain how the tools are intended to work and to help users understand their limitations. It is not intended to replace instructions provided by a government agency, bank, lender, employer, school, application portal, or other organization.
atoolix is a utility website focused on making common browser-based tasks easier to complete without requiring dedicated desktop software.
We document the intended purpose and limitations of our tools so users can make informed decisions about whether a particular tool is appropriate for their task.
For information about the site and how to contact us, visit our About page and Contact page.
For legal and privacy information, see our Privacy Policy, Terms and Conditions, and Disclaimer.
The exact implementation differs by tool. Depending on the feature, a user may enter values, select options, choose files, process them in the browser, or use a service that requires server-side processing.
STEP 1
Select the tool that matches your task.
STEP 2
Provide the required values, settings, or supported files.
STEP 3
Run the tool using the available browser or service functionality.
STEP 4
Check the output before relying on it or submitting it elsewhere.
Some tools are designed to process files locally in the browser. When processing is genuinely browser-only, the selected file can be processed on the user's device rather than being sent to a remote server.
Processing behavior can differ between tools. Do not assume that every feature uses browser-only processing. Check the individual tool page and our Privacy Policy before submitting confidential or sensitive information.
Users should keep backup copies of important files and avoid uploading information that is unnecessary for the task.
The tools are intended for modern versions of Chrome, Edge, Safari, and Firefox. Actual behavior can vary according to the browser version, device, available memory, file size, and browser features.
If a tool does not behave as expected, update the browser, refresh the page, try another supported browser, or reduce the size of the input where appropriate.

Tool outputs are generated from the inputs, assumptions, supported formats, and processing methods available at the time you use the tool. Outputs can contain errors or differ from results produced by other software.
Always review important calculations, converted files, image dimensions, PDF output, and other generated results before using them for an official, legal, financial, academic, employment, government, or business purpose.
Requirements published by governments, banks, lenders, schools, employers, application portals, and other organizations can change. When a specific external requirement applies, verify it against the current requirements published by the organization receiving your submission.
Finance calculators are especially intended for estimation and comparison. They are not financial advice, loan offers, investment recommendations, or guarantees of future results.
Processing depends on the individual tool. Many browser-based tools are designed to process files locally in the browser. Where server-side processing is required, the relevant tool should explain that behavior. Check the specific tool page and the Privacy Policy before uploading sensitive information.
Most tools are designed for modern mobile and desktop browsers. The exact experience can vary by browser, device, file size, and available browser capabilities.
The tools are designed to be used through a web browser and generally do not require desktop software installation.
Modern versions of Chrome, Edge, Safari, and Firefox are generally supported. Some advanced browser features may behave differently depending on the device and browser version.
Some tools may impose practical file-size or processing limits. Check the individual tool page for the applicable limits and supported formats.
The file may use an unsupported format, exceed a size limit, be damaged, or fail another requirement of the particular tool. Check the tool instructions and try a supported format.
Compression can change image or document quality. The amount depends on the format, source file, and selected settings. Review the resulting file before using it.
No. Finance calculators provide estimates based on the values and assumptions entered by the user. Actual lender, bank, investment, tax, or other financial results may differ.
Important financial decisions should not be based solely on a calculator result. Verify assumptions and figures with the relevant financial institution or an appropriately qualified professional.
