Convert XLSX to PDF
We turn XLSX into PDF right in your browser — the file never goes to a server.
What you will lose
Nothing important: the target format does everything the source does.

XLSX
Good at
- Formulas, pivot tables and charts in one file
- Opens in Excel, Google Sheets and LibreOffice
- Several sheets instead of a pile of separate files
Awkward about
- Heavy for a plain table — CSV is readable by anything
- Formulas sometimes evaluate differently across apps
- Printing without setup spills across pages
Use it when
- You need calculations, not just rows and columns
- People read the data, not programs
- The table will keep growing and recalculating
Good at
- Looks the same everywhere: fonts, margins and line breaks are fixed
- The one format any office will accept without argument
- Holds text, vectors and photographs in a single file
Awkward about
- Hard to edit: it is a format for reading, not for changing
- Weight depends on what is inside — a scanned page can weigh as much as a book
- Text inside a scan stays a picture until something recognises it
Use it when
- The document is being sent, printed or filed somewhere official
- The layout must not shift on someone else’s device
- Loose pages need to become one file
Common questions
- Does the file get uploaded to a server?
- Yes, this pair needs the server: browsers cannot encode that format. The file and the result are deleted within a couple of hours and never shared.
- Will transparency survive?
- Yes, PDF supports transparency, so semi-transparent edges stay as they were.
- Can I get the original quality back afterwards?
- Yes, PDF supports lossless compression, so you can go back to the original.
- How many files, and how large?
- Up to 5 files at a time, 50 MB each. No sign-up, no watermarks.
