No — that is the whole point when you’re sharing personal job paperwork. Your documents are opened, rendered with pdfjs, masked by flattening and merged with pdf-lib entirely on your device, with no server, no API and no CDN call for your files; the page even works offline once cached. Nothing is sent, logged or stored. That is exactly why you should never use a random online “merge documents” site — those upload your certificates, ID and salary slips to a stranger’s server. Here, only the merged PDF or ZIP you choose to export leaves the page, and closing the tab discards everything.

A typical job application needs a tailored resume / CV, often a cover letter, a passport-size photo, a government photo ID proof and your educational certificates / marksheets (10th, 12th, graduation, post-graduation). Experienced candidates also bring experience and relieving letters confirming role and tenure, previous offer / appointment letters and — only if the employer requires it — the latest salary slip; freshers bring internship / project certificates, transcripts and a references list; and government jobs additionally require the final submitted application form, the admit card / hall ticket / call letter, and any category / caste, domicile / residence or income / non-creamy-layer certificate being claimed. Creative, design and developer roles often add a portfolio or work samples. The exact required documents, formats and order vary by employer, role, country and job portal, so always follow the job posting and the employer’s official list. This tool gives you a checklist per profile to organize against, but it is general guidance, not the employer’s official list.

Yes. Many employers and job portals prefer all your supporting documents in a single, ordered PDF. Upload your resume / CV, cover letter, ID, photo, certificates / marksheets and any profile-specific documents (images or PDFs), arrange them with the up/down arrows, set the applicant name and the position / company, and export one merged PDF that starts with an auto-generated cover/index page listing every document. If a portal instead wants each file separately, export the ZIP, which contains each document flattened (masks baked in) on its own. Both are built entirely in your browser, so nothing is uploaded.

Share only what is genuinely required and mask sensitive details: you are not obliged to disclose your current salary, and revealing it can weaken your negotiation, so consider masking the figure on a salary slip; also mask full ID / PAN numbers you don’t need to share early in the process. In this tool you draw black boxes over those details; the masking is real, because each box is painted onto the page image and the PDF is rebuilt from those images, so the hidden content is physically gone with no recoverable text layer. Most importantly, be alert to job-offer scams: credible employers never ask you to pay application / training fees, and never ask for sensitive ID or bank details before a real interview — if a “recruiter” demands money or those details up front, verify the company on its official site first and cut off contact, because it is almost certainly a scam. This tool only prepares and packages your own copies; it does not apply for you, screen you or guarantee an interview.
