Save favourite tools and reopen recent ones
Click the save button on any tool card in the AltFTool directory to add it to the Saved tab, and any tool you open appears automatically in the Recent tab (up to 12). Both lists are stored in your browser, need no account, and do not sync between devices.

How to save a tool
Saving builds a small personal toolbox inside the tool directory, so the handful of tools you use every week are one click away.
Open the directory
Go to /tools/all, or any category hub such as /tools/developer.
Find the tool
Search or scroll to the tool you want, for example the JSON Formatter or the Image Compressor.
Press save
Use the save button on the tool card. Its label changes to 'Remove' so you can undo it the same way.
Open your toolbox
Switch the directory view from All to Saved, or open /tools/all?view=favorites directly. Bookmark that URL for one-click access.
How the Recent tab works
You do not need to do anything for Recent. Each time you open a tool page, it is added to the top of the list, which keeps the 12 most recent tools. Open the Recent view in the directory, or go to /tools/all?view=recent, to see them.
If a tool is later renamed or merged into another one, the directory skips the old entry rather than showing a broken link.
Where the lists are stored
Saved and recent tools are kept in your browser's local storage on this device. Nothing is sent to an AltFTool server, and no account is involved. That has two consequences worth knowing:
- The lists do not follow you to another browser, phone or computer.
- Clearing site data, using a private window, or some privacy extensions will empty them.

Frequently asked questions
Do I need an account to save tools on AltFTool?
No. Saved and recent tools are stored in your browser's local storage, so they work without signing in.
Why did my saved tools disappear?
The list lives in browser storage. Clearing cookies and site data, browsing in a private window, or switching browser or device will show an empty Saved tab.
How many recent tools are kept?
The Recent tab keeps the 12 tools you opened most recently, newest first.
