Question 1

Is ToolsGuru really free to use?

Accepted Answer

Yes, all tools on ToolsGuru are free to use. The site is supported by advertising through Google AdSense. There are no hidden fees, subscriptions, or premium tiers.

Question 2

How does ToolsGuru protect my privacy?

Accepted Answer

We do not ask for personal information and there are no accounts. Your files are processed in your browser. The site uses Google Analytics and Google AdSense, which may set cookies and collect usage data; see our Privacy Policy. A few tools contact other services; they are listed in the answer on network requests below.

Question 3

Do I need to create an account to use the tools?

Accepted Answer

No, you don't need to create an account or register to use any of our tools. Simply visit the tool page and start using it immediately. There is nothing to sign up for.

Question 4

Are my files uploaded to your servers?

Accepted Answer

Not by the file tools. Image, PDF, text, hash and similar tools process your data with JavaScript in your browser, so the file is not sent to ToolsGuru servers. A few tools contact other services; see the answer on network requests below.

Question 5

What browsers are supported?

Accepted Answer

ToolsGuru works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend keeping your browser updated to the latest version for the best experience and security.

Question 6

Can I use ToolsGuru on mobile devices?

Accepted Answer

Yes! Our tools are designed with responsive layouts that work on smartphones and tablets. However, some tools that require file manipulation work best on desktop devices due to screen size and file system access.

Question 7

How do I report a bug or suggest a feature?

Accepted Answer

We welcome your feedback! You can contact us at info@aleenaltd.com with bug reports or feature suggestions. Please include as much detail as possible, including the tool name, browser, and steps to reproduce any issues.

Question 8

Why do some tools take time to process?

Accepted Answer

Since most processing happens in your browser, the speed depends on your device's processing power and the size of the files you're working with. Larger files naturally take longer to process.

Question 9

Are there any file size limits?

Accepted Answer

Limits depend on the tool and on your browser's memory; for example Video to Audio accepts up to 500 MB per file and Image Converter 50 MB. Very large files can be slow or fail on devices with little memory.

Question 10

Can I use ToolsGuru for commercial projects?

Accepted Answer

Yes. There is no fee for using the tools for personal or work projects. See our Terms & Conditions for the details.

Question 11

How can I check that my files are not uploaded?

Accepted Answer

Open your browser's developer tools (usually F12), go to the Network tab and filter by Fetch/XHR, then use a file tool such as the PDF Joiner or Image Converter. You should see the page's own assets, fonts, analytics and ad scripts load, but no request that sends your file to a converter service. Our guide “How ToolsGuru keeps files on your device” walks through this step by step.

Question 12

Which tools need an internet request to work?

Accepted Answer

Most tools run fully in your browser once the page has loaded. Exceptions: the Debugging & Testing API and GraphQL testers send requests to the address you enter; the Carbon Code Screenshots tool sends your code to carbon.now.sh (a third-party site) to show the preview; the Sitemap Extractor can fetch a sitemap directly from another site if that site allows it (or you can paste the XML instead). Do not enter private URLs, tokens or code you would not share with those sites.

Question 13

Is anything saved on my device?

Accepted Answer

Your browser stores your theme choice, and a few tools keep data in local storage so your work is still there when you come back: the Online Notepad autosaves your text, and the Flashcard Maker saves your card sets. This stays on your own device, and you can clear it by using the tool's clear option or by clearing your browser's site data.

Question 14

Are the generated passwords and random numbers secure?

Accepted Answer

The Password Generator uses your browser's built-in cryptographic random number generator (crypto.getRandomValues), and the Hash Generator uses the browser's Web Crypto API. Generated values are created on your device. As with any password tool, store the result in a password manager rather than in plain text.

Question 15

What kinds of tools are available?

Accepted Answer

ToolsGuru has more than 70 free tools in categories including PDF tools (merge, split, rotate, watermark, convert), file converters for images, PDFs and video-to-audio extraction, developer tools (hashes, UUIDs, Base64, URL and HTML encoding), text tools (word counter, case converter, sort and clean lines), calculators, student tools such as GPA and grade calculators, and SEO helpers such as the meta tag and robots.txt generators. Use the Categories menu or the homepage to browse them all.

Question 16

Which PDF tools do you offer?

Accepted Answer

There are separate tools for joining PDFs, splitting by page range, deleting pages, rotating pages, adding a text watermark, viewing and editing metadata, converting images to PDF, converting PDF pages to images, and a general PDF editor. They are built on the open-source pdf-lib and PDF.js libraries and run in your browser.

Question 17

Can I merge or combine PDF files without uploading them?

Accepted Answer

Yes. The PDF Joiner reads your files in the browser, lets you drag them into the order you want, and builds one merged PDF on your device, which you then download. Nothing is sent to a server to do the merge.

Question 18

What can the QR Code Generator create?

Accepted Answer

It creates QR codes for plain text, website URLs, WiFi network logins and vCard contact cards. You can change the size, margin, colours and error-correction level, and download the result as a PNG or an SVG. The codes are static, so they contain your data directly and do not depend on ToolsGuru to keep working.

Question 19

What happens if a tool does not work for me?

Accepted Answer

First check that your browser is up to date and try reloading the page; very large files may need more memory than your device has free. If the problem continues, email info@aleenaltd.com with the tool name, your browser and device, and what you did before the problem happened. Screenshots help.

Question 20

How do I find the right tool?

Accepted Answer

Browse by category from the menu, or start from the How to Use page and the Guides section, which explain common tasks such as converting photos, merging PDFs and choosing between hashes, UUIDs and passwords. Each tool page also has its own guide, FAQ and links to related tools.
