Sending PDFs that get read: applications, invoices and formal submissions
The difference between a document that lands well and one that gets bounced is rarely the content. It is usually the file.

Always send PDF, never the source file
A Word document renders differently depending on the reader's fonts, version and platform. Your careful two-page CV can arrive as three pages with an orphaned heading. PDF fixes the layout, so what you see is what they see. Export from your editor rather than printing to PDF where possible — direct export keeps hyperlinks working.
Name the file for the person receiving it
The recipient may be saving dozens of files into one folder. Include your name and the document type: dave-mitchell-cv.pdf, not cv-final-v3-updated.pdf. Avoid spaces and special characters, which some upload systems mangle. Keep it under about 40 characters.
Merge into one pack, in the order they will read it
- Cover letter first, then CV, then certificates and references.
- For invoices, put the invoice ahead of supporting receipts and timesheets.
- One file beats five attachments — it cannot be partially lost or read out of order.
- Check the page order and orientation after merging, before sending.
Respect the size limit before you hit send
Portals commonly cap uploads at 2–5 MB and email at 10–25 MB. If a text CV is several megabytes, an embedded photo or a scanned signature at full resolution is the reason. Compress moderately, then check the smallest text is still crisp. Never compress so far that a scanned signature becomes a smudge.
Final checks that take one minute
- Open the finished file in a plain reader, not just the tool that made it.
- Check document properties for an author name or file path you do not want shared.
- Confirm any hyperlinks are clickable.
- View it on a phone — a large share of first reads happen there.
- Send it to yourself first if the submission is important and one-shot.
