XPS File Too Large? How to Reduce It and Convert Successfully

XPS2PDF.co.uk accepts files up to 25 MB per file. If your file exceeds that, the upload will be rejected before conversion starts. The most common culprits are high-resolution scans, large embedded images, and documents with many pages.

This guide explains what makes XPS files large and gives you practical steps to bring the size down — or break the document into parts — so conversion goes through cleanly.

Why XPS files get oversized

An XPS file is a ZIP archive containing XAML markup, embedded fonts, and all images at whatever resolution they were inserted. Unlike PDF, there is no built-in XPS compression setting you can dial down at print time — what goes in stays in. Three things dominate file size:

• Scanned pages at high DPI. A 300 DPI colour scan of a single A4 page can run to 1–3 MB. A 50-page document scanned at 600 DPI can easily exceed 100 MB before the XPS is even created.
• Embedded full-resolution photographs. If the source document contains high-res photos that were never downsampled, each one carries its original file size inside the XPS container.
• Many pages. Even a modest page size multiplies across hundreds of pages. A 300-page report can pass 25 MB from text alone if the fonts and layout are complex.

The ZIP container around all this does apply compression, but if the content is already compressed (JPEG images, for example), the outer ZIP gains very little.

Reduce scan DPI before creating the XPS

If the XPS was created by scanning a paper document, the scan settings are the fastest lever. Re-scan at a lower resolution:

• 300 DPI is sufficient for text documents intended for screen reading or archival PDF. It is the default output resolution for the JPG option on this converter.
• 150–200 DPI is acceptable for documents that will only be read on screen and not printed.
• Scanning in greyscale instead of colour typically cuts file size by a factor of three.

If you no longer have the paper originals and the XPS is the only copy, skip to the splitting options below.

Split a large document into smaller parts

If reducing DPI is not an option, splitting the document is the next best approach. The converter accepts up to 20 files per batch, so you can upload several smaller parts in one go and then combine the resulting PDFs afterwards.

To split a large document, re-open it in the application that created it and print specific page ranges to the Microsoft XPS Document Writer. For example, pages 1–40 become part1.xps, pages 41–80 become part2.xps, and so on. Each chunk should come in well under 25 MB.

If the original source file is no longer available, the same technique works if you can open the XPS in the Windows XPS Viewer and print selected pages to the XPS Document Writer to create smaller sub-files.

Re-export from the source application

If you have the original Word, Excel, or other Office document, export it directly as PDF rather than going via XPS. Office applies image downsampling and PDF compression automatically during a PDF export, whereas the XPS Document Writer preserves everything at full quality. The resulting PDF will typically be significantly smaller and is already in the format most readers need.

For documents that genuinely must stay as XPS, re-saving with the XPS Document Writer from a lower-resolution version of the source (for instance, a version with images compressed inside Word) will produce a smaller XPS without any loss of text content.

Check the real file size before uploading

Right-click the file in Windows Explorer and choose Properties to see the exact size in bytes. The 25 MB limit is measured against the file as it sits on disk — the same figure Windows shows. If the file is 24.9 MB it will upload; if it is 25.1 MB it will not. There is no automatic resizing on upload.

After reducing size, drop the file into the converter above. If conversion still fails for a different reason — such as a password or a corrupted container — the relevant guides are linked below.

Frequently asked questions

What is the maximum XPS file size for XPS2PDF.co.uk?

The limit is 25 MB per file. You can upload up to 20 files in a single batch, so splitting a large document into parts and uploading them together is a practical workaround.

My XPS file is 30 MB — will compressing the ZIP help?

Probably not much. The XPS container already uses ZIP compression. If the images inside are JPEGs (which are already compressed), re-zipping the outer container saves very little. The effective fix is to reduce the resolution of the images or scans before the XPS is created.

Can I split an XPS file without the original source document?

Yes, if you have the Windows XPS Viewer. Open the XPS, then File → Print, select the Microsoft XPS Document Writer as the printer, and enter a page range. This creates a new, smaller XPS from just those pages.

Why is my 10-page scanned XPS over 25 MB?

High-DPI colour scans are the most common reason. A single A4 page scanned at 600 DPI in colour can exceed 3 MB. Re-scan at 300 DPI in greyscale and the same 10 pages will typically come in well under 10 MB.

Does converting to JPG instead of PDF produce smaller output files?

The JPG output from this converter renders each page at 300 DPI as a JPEG image. Multi-page documents download as a ZIP of separate images. The input file still needs to be under 25 MB; JPG output does not bypass the upload limit.
