Getting Started with LocallyTools
Visit the LocallyTools official website and start using it right away—no installation required.
On the homepage, browse by category or press ⌘K to search for the tool you need (for example, "Split PDF" or "JWT Decode").
After choosing a tool, drag your file onto the page or click to upload, set the parameters as needed, then run the operation.
Once processing is complete, download the result; you can continue using it offline in the same browser later.

Frequently Asked Questions
Q: As a collection of local tools, what are LocallyTools' core advantages, and what scenarios does it help users with?
A: LocallyTools' core advantages are security, free usage, and offline capability. It works without an internet connection, charges nothing, and is committed to protecting your file data. The scenarios it addresses include: image processing (such as compressing, converting formats, and cropping images to meet different needs), PDF processing (for example, splitting/merging PDFs and turning PDF pages into images for easier viewing or sharing), and development tasks (such as generating UUIDs, handling JWTs, and formatting code to boost development efficiency)—covering many practical needs in both work and everyday life.
Q: For users who need to handle PDF files, what specific features does LocallyTools offer? Can it convert PDFs to multiple image formats and edit PDF pages?
A: LocallyTools' PDF tools meet these needs with two categories of features. First, PDF format conversion: it supports converting PDF pages into four image formats—JPEG, PNG, WebP, and AVIF. Second, PDF page editing: it supports splitting a PDF into multiple files, combining multiple PDFs into a single new PDF, and deleting specified pages from a PDF, fully covering users' needs for PDF conversion and page editing.
Q: Is my file data secure?
A: Absolutely secure! All file processing in LocallyTools is done locally on your device, so your file contents never leave your device. We do not collect, store, or process any of your personal files—they are entirely under your control. This local-processing approach technically guarantees your privacy and security.
