Guides worth reading
How these tools handle your files
Free should not mean careless. Here is what to expect.
In your browser
Image, PDF, text, color and calculator tools do their work on your device. Your files are not uploaded to our servers.
Live-data tools
SERP, backlink, breach, SSL and page speed checkers must ask outside services for data. The tool page tells you when that happens.
Estimates, not advice
Tax, loan and investment calculators give estimates. Confirm important figures with the tax authority or a qualified adviser.
How we are funded
The site is supported by ads. Read our Privacy Policy and Cookie Policy.

Frequently asked questions
What is SkillsInsider?
SkillsInsider is a free collection of online tools and guides for freelancers, developers and creators. It covers PDFs, images, SEO, development, finance and everyday calculators. Most tools run in your browser, so there is nothing to install and no account to create.
How many tools are there?
The site map lists more than 200 tool pages. This homepage shows the most-used ones; the All Tools directory has the full list.
Are the tools really free?
Yes. You do not pay, you do not sign up, and there is no daily limit. The site is supported by advertising.
Is my data safe? Do my files get uploaded?
For most tools, such as image, PDF, text, color and calculator tools, the work happens in your browser and your files are not sent to us. Some tools must contact an outside service to get live data, for example the SERP, backlink, breach, SSL and page speed checkers, and the tool page says so. Do not paste passwords or private documents into any online tool unless you are comfortable with how it works.
Are the tax and finance calculators accurate?
They give estimates based on the rates and rules built into each tool. Tax rules change every year, so confirm the result with the tax authority (for Pakistan, FBR) or a qualified adviser before you file or decide anything.
What is a HEIC image and why convert it?
HEIC is the photo format iPhones use by default. It saves space, but many Windows apps, Android phones and websites cannot open it. Converting to JPG or PNG makes the photo work almost everywhere.
Why crop and resize images before uploading?
Cropping sets the shape, such as square for avatars or 16:9 for banners. Resizing cuts file size. Together they help pages load faster and stop platforms from cutting off your image.
Which cookies do you use, and can I change my choice?
We use a small cookie to remember your theme and your cookie choice, and Google AdSense uses cookies to show ads. If you reject, only non-personalized ads are requested. You can change your choice at any time with Cookie settings in the footer.
Do the tools work on phones and tablets?
Yes. The site works on phones, tablets and desktops, though very large files can be slow on older devices.
How do I report a bug or suggest a tool?
Use the contact page or email [email protected] with what went wrong or what you would like to see.
