A prospective client asks for your portfolio. You email a link to your website. Two weeks later, no reply. They probably looked, probably forgot, probably moved on.
A portfolio PDF stays in the inbox. It can be forwarded to the client's boss. It can be re-opened on a flight. Websites can't do any of that.
Curate ruthlessly
5-8 case studies max. Each case study one to two pages. Lead with your strongest work — the client typically reads the first two and skims the rest. Tailor the selection to the client's industry where possible. A generic portfolio loses to a tailored one every time.
Build the case studies
Each case study: project title, client (or generic descriptor if NDA'd), problem, approach, outcome, image. Build in your design tool of choice and export to PDF. Convert from Word if you're a writer rather than a designer. Convert images if you're including visual work.
Combine into one file
Use merge PDF to combine cover, contents, case studies, and contact page. The cover page should have your name, discipline, and contact details — recognisable at thumbnail scale. The contact page should make next steps obvious (email, phone, website).
Compress for email
Portfolios run heavy with images. Compress PDF to under 10MB for easy email. Test on a phone — if case studies still read clearly, you've compressed correctly. Keep the original high-resolution version for any print needs.
FAQ
How long should a freelance portfolio be?
10-20 pages including cover. Beyond that, attention drops. Quality of case studies beats quantity.
Should I include rates?
Usually no — rates depend on scope and engagement model. A portfolio sells the work; rates are a conversation.
Can I update the portfolio per client?
Yes — tailored portfolios convert better. Maintain a master document with all case studies; export tailored versions per pitch.
Should the portfolio be password-protected?
Usually no — the portfolio is sales material. For NDA'd work shown in samples, redact identifying details rather than locking the whole file.
A portfolio PDF wins work that a website link doesn't. Build it in Flint and your next pitch lands harder.
