Excel to PDF on Desktop

Drag and drop is the fastest way to add files. Select several in your file manager and drop them onto the upload area together — they are added in one go, and for tools that accept multiple files you can drop more on afterwards to append to the list.

The whole interface is keyboard-navigable. Tab moves between controls in a sensible order, the upload area responds to Enter and Space, and focus outlines are always visible so you can see where you are. Nothing requires a mouse.

A desktop's memory headroom is the real advantage. Files up to 40 MB are comfortable on a machine with a few gigabytes free, where a phone would struggle. Operations that re-render pages also finish several times faster on a desktop processor.

The workbook is parsed by SheetJS, which reads XLS, XLSX and CSV and exposes each sheet as a two-dimensional array of cell values. The first row of each sheet becomes the table header and the rest becomes the body.

Those rows are handed to jsPDF's autoTable layout engine, which measures the content, works out column widths, applies the header and alternating-row styling, wraps long values inside their cells, and flows the table across as many pages as it needs. When you convert every sheet, each one starts on a fresh page with its name printed above the table.

Your files are not uploaded. When you add a XLS, XLSX or CSV file, your browser reads it from your device into the memory of the tab you are looking at, and the excel to pdf operation runs there using your own processor. Nothing is transmitted to any server at any point.

That means there is no file for anyone to store, no retention policy to trust, and no deletion schedule to take on faith. The document exists only in the memory of an open browser tab, and it is released the moment you close it, reload the page, or press start over.

The site uses standard anonymous analytics to count page views and how often each tool is used. Those events record which tool ran and whether it succeeded — never a file name, never file contents, and never anything that could identify a document or the person processing it.

No account is required, so no personal information is collected. There is no profile, no history and nothing tied to an identity, because no identity was ever created.

The strongest security property this tool has is structural: your file never travels anywhere, so there is no transmission to intercept and no server-side copy to breach. This is not a policy that could change — it is a consequence of where the code runs.

You can verify it in about thirty seconds. Open your browser's developer tools with F12, select the Network tab, and use the tool. You will see the page's scripts load — including the PDF libraries, which are fetched on demand the first time a tool runs — and then nothing further. No request carrying your document is ever made.

For a stronger test, disconnect from the network once the page has loaded. The tool will keep working exactly as before, which is only possible because nothing is being sent.

Uploaded files are validated in the browser before anything runs: the extension must match what the tool accepts, the file must not be empty, and it must be within the size limit. Malformed documents produce a clear error and a retry option rather than a silent failure.

Being clear about limits is more useful than a feature list that quietly omits them. Only cell values are converted — charts, images, shapes, conditional formatting and cell colours are not reproduced — and very wide tables can become cramped even in landscape.

If you need capabilities beyond that — redaction, PDF/A conformance, OCR, or scripted batch processing across thousands of documents — dedicated desktop software genuinely earns its licence fee, and this is not trying to replace it. For the specific job of producing a PDF, everything you need is on this page.
