Many applications — visas, jobs, admissions, loans — ask for your documents as a single PDF, not a pile of separate images or files. Combining them is quick once you know which tool to use for each starting point.
Combining photos or scans into a PDF
If you have photos or phone scans of documents, use Image to PDF (it accepts JPG, PNG and WebP). Add your images, put them in the right order — each becomes one page — and download a single PDF. On an iPhone, photos are HEIC; convert and combine them in one step with HEIC to PDF.
Merging existing PDFs
If you already have several PDF files — say, monthly bank statements or separate certificates — use Merge PDF. Add the files, drag them into the order you want, and merge into one document. There's a dedicated guide for combining bank statements too.
Getting the order and size right
Order matters for documents, so arrange files before combining (oldest to newest is common for statements). After merging, if the file is too big for an upload, run it through Compress PDF or a target like 500 KB. To standardise odd page sizes, resize the PDF to A4.
Why do it in the browser
Combining documents online usually means uploading them to a stranger's server. With ToolsKaro, the PDF is built entirely on your device, so your personal papers never leave your browser — the safe way to handle IDs, statements and certificates.
