Getting started
Web4Tools is organized around practical browser-based tools. Open a tool from the home page or the app drawer, follow the instructions shown by that tool, and review the result before using it elsewhere.
Tool categories
PDF utilities for common document workflows, including merge, split and related operations.
Image
Image utilities for common file-size and image-processing tasks.
Developer
JSON, Base64, UUID, sitemap and other development-focused utilities.
Are Web4Tools tools free?
The Web4Tools homepage describes its tools as free to use. Individual third-party services or future features may have their own terms or limitations.
Do I need to install software?
Most Web4Tools utilities are designed to run in a modern web browser, so no separate desktop installation is required for the browser workflow.
What should I do before uploading a file?
Check the specific tool's instructions and processing information first. Avoid uploading passwords, private keys, highly sensitive personal information or confidential files unless the tool is appropriate for that material.
Where can I find PDF tools?
Open the Web4Tools app drawer and select Tools4Pdf, or visit the PDF tools service directly from the footer.
Where can I find developer tools?
Use the Tools4Dev option in the app drawer. The current ecosystem includes utilities such as JSON Formatter, Base64 Encoder, UUID Generator and XML Sitemap Generator.
Can I rely on the finance calculator results?
Use them as estimates for planning and education. Actual loan, EMI or investment outcomes can differ because of rates, fees, taxes, timing and product-specific terms.
