No — that is the whole point, because exam files include your face, signature and ID. Your photograph and signature are measured and resized on your device with pica, and your supporting documents are rendered with pdfjs, masked by flattening and merged with pdf-lib, all from this app’s own bundle 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 not use a random online “resize photo for exam” or “merge documents” site for your photo, signature and certificates — those upload your most personal files to a stranger’s server. Here, only the compliant photo and signature and the merged PDF or ZIP you choose to download ever leave the page, and closing the tab discards everything.

There is no single size — that is why the tool has exam presets. SSC commonly wants a photo of about 200×230 px at 20–50 KB and a signature about 140×60 px at 10–20 KB in JPEG; IBPS and other bank exams are similar (and also ask for a left-thumb impression and a handwritten declaration, which you can add as documents); UPSC allows a larger photo up to about 350×350 px at 20–200 KB and a signature at 20–100 KB; Railway (RRB) tends to use about 320×240 px photos at 30–70 KB; and state PSCs vary widely. The photo should be recent (often within three months) on a plain light / white background, and the signature should be black ink on white in running handwriting, not block capitals. Pick your exam to load its spec, upload your files, and the tool validates and auto-fixes each to the right format, pixels and KB — but because the exact numbers differ per exam and change, and wrong size / format is the most common reason uploads are rejected, always confirm the official exam notification / portal and use the Custom preset to enter the exact requirement.

A typical government-exam document set includes a government photo ID, your Class 10 certificate (often the proof of date of birth) and Class 12 marksheet, and your graduation / degree certificate for graduate-level posts. If you claim a reservation or relaxation you add the relevant certificate in the prescribed format: a category / caste certificate (SC / ST / OBC, usually non-creamy-layer and current for OBC), an EWS income & asset certificate valid for the current financial year, a PwD / disability certificate from the competent medical board, an income / non-creamy-layer certificate, or an ex-serviceman / sportsperson proof. State PSC and state-government posts usually also need a domicile / residence (PRC) certificate. You generally also keep the admit card / hall ticket and a printout of the submitted application form. Importantly, category, EWS and PwD certificates are often required only at the document-verification stage rather than with the online form, so always check what the specific exam notification asks for and when. The tool gives you a checklist per exam to organize and merge these into one PDF, but it is general guidance, not the official list for your exam.

No — the tool prepares your files only. It does not fill in your application, does not submit anything to the exam portal, and does not pay any fee; you still log in to the official portal yourself and upload the files it asks for. Two honest caveats matter. First, the photo / signature specs and required documents differ per exam (SSC vs UPSC vs IBPS vs Railway vs State PSC) and change over time, so the presets are common values, not the guaranteed requirement — always confirm the official exam notification / portal and use Custom to enter exact numbers. Second, auto-fix re-encodes the image: compressing to hit the KB window can reduce quality and cropping to an exact size can trim the edges, so preview the result before you submit. The document masking is real (boxes are burned into the page image so there is no recoverable text underneath), but you place the boxes — cover only what you don’t need to share and review every page. And beware any site or “agent” that asks for fees or your documents up front.
