Tools for

Job seekers

Check your CV against the job, make the photo and the PDF the form wants, and work out what the offer pays after tax — without signing up to anything.

27 tools · 25 free with no account · 2 free to try with one

Applying for jobs is mostly admin. The portal wants a photo of a certain size, the documents merged into one PDF under 2 MB, a signature on the form, and a CV that matches words in a job description nobody wrote clearly. Then an offer arrives as a CTC or a gross salary, and the number that matters — what lands in your account each month — is not in the letter.

Everything here except the CV screener runs in your browser: your passport photo, your certificates and your payslips stay on your own device. The CV screener is an AI tool and says so on its page: it sends the CV and the job description to a model, with personal details like your phone number and email masked on your device first.

Matched to the job, the right length, and read once more before it goes.

Frequently asked questions

Is my CV sent anywhere?

Only by the CV screener, which is an AI tool and says so at the top of its page. It masks your email, phone number and ID numbers on your device before anything is sent, shows you what will go, and nothing is stored after the answer comes back. Every other tool here runs entirely in your browser.

Will the passport photo be accepted?

The tool lays out the photo at the official size for the country you pick and prints it as a sheet. Acceptance still depends on the photo itself — lighting, expression, a plain background — so read the checklist on the page before you print, and check the authority’s current rules.

My offer letter gives a CTC. What will I actually get?

Use the CTC to take-home calculator for India, or the UK take-home pay calculator for a gross salary in the UK. Both show the deductions line by line, so you can see where the difference between the headline and your account goes.
