Most UK illustrators end up with both a PDF and a website, then quietly wonder which one is doing the work. The honest answer is that the format matters less than the moment: what you are sending, who will open it, and what they need to decide. A children's book editor reading a submission at her desk wants something different from a brand manager forwarding your link to three colleagues.

What Each Format Is Actually Good At

The PDF portfolio

A PDF is a piece of theatre you control. Page order, image size, margins, pace — all fixed. It behaves like a printed portfolio, which is why it still works so well for submissions: agents, art directors and publishers are used to receiving them, and they can read one without an internet connection. For a picture book pitch, spreads in sequence do something a website rarely manages — they reproduce the rhythm of turning pages.

Its weaknesses are equally fixed. Once sent, it is frozen, and a PDF from three years ago may still be circulating with work you have since improved on. Large files clog inboxes, and few clients will tell you the email bounced. Your images cannot be found in a search, and you will never know whether they were opened.

The website portfolio

A website is a home rather than a handout. Update it once and every future visitor sees the current version. It works on a phone, it can be linked from an email signature or a social profile, and search engines can read it. If someone wants to check whether you are still working, still available, or still based in Manchester, the site answers in seconds.

The cost is upkeep. Domains and hosting renew every year, images need compressing, and a neglected news section from 2019 undermines everything above it. There is also the temptation to show all of it, which is how a portfolio becomes an archive.

Sharing and Delivery: Small Decisions, Big Effects

How you send work is often noticed more than you would expect. A few habits make both formats land better.

• Name files properly. Rosa_Adeyemi_Illustration_Portfolio.pdf is findable six months later; portfolio-final-v3.pdf is not.
• Keep attachments lean. Many mail servers reject or quarantine large files. Compress sensibly, or send a download link instead.
• Host your PDF on your own site. Then you can link to it, replace it when the work changes, and see roughly how many people are reading it.
• Use a clean address. Your own domain reads as professional; a long free subdomain reads as temporary.
• Write three lines of context. Who you are, what the work is for, what you would like to happen next. Never send a bare link.
• Open both on a phone before you send. Half of your recipients will.

Updates and the Problem of the Stale PDF

Illustrators change. Styles sharpen, subjects shift, and work you were proud of in March can look thin by autumn. A website absorbs that in an afternoon. A PDF has to be rebuilt and re-sent, which means the older version keeps doing the rounds long after you have moved on.

The workaround is to treat PDFs as tailored documents rather than your master portfolio. Build two or three: one for editorial and commissioning, one for children's books, one for commercial and packaging work if that is a direction you want. Refresh them twice a year, date them, and keep the newest version on your site.

Being Found: Where the Website Does the Long Work

Search is rarely how a client finds an illustrator they already know, but it is often how they find one they do not. An art director looking for a botanical illustrator in Bristol, or a museum wanting someone who can draw natural history specimens, will start with a search engine. Your website can appear in those results; your PDF, sitting in someone's downloads folder, cannot.

The basics are unglamorous and they work: descriptive page titles, alt text on every image, sensible image filenames, a page per project, and enough written copy that search engines understand what you do and where you are. A short news or journal section, added to a few times a year, keeps the site alive. Instagram and similar platforms help with discovery too, but you are borrowing that audience. The website is the only place you own.

First Impressions: The First Ten Seconds

Assume your work is opened on a phone, on a train, between meetings. In a PDF, that often means pinch-zooming a double-page spread in a portrait window, which is not the experience you designed. On a website, a well-built page will simply fit.

Against that, a PDF offers something a scrolling grid struggles to give: a considered order. Six images chosen for one specific client, arranged with intent, will almost always outperform your entire archive. Relevance beats volume.

A portfolio is not a gallery. It is an answer to a question the client is already asking.

So ask what they need. A publisher wants to see characters, sequence and narrative control. An advertising art director wants to see how your style holds up under a brief and a deadline. A magazine wants ideas and speed. Whichever format you choose, the selection should say: I understand your problem.

A Practical Hybrid That Works

You do not have to choose. Most working illustrators are best served by both, used for different jobs.

1. Keep a website as your permanent home: a home page with your strongest work, project pages, an about page with one clear sentence about what you do, and a contact address that is not a form alone.
2. Build two or three tailored PDFs, each eight to twelve images, aimed at the kinds of client you want more of.
3. Host those PDFs on your site so they have a link you can send in a sentence.
4. Lead with the link in a first email. Attach the PDF when the brief calls for it, or when the client asks.
5. Refresh the PDFs twice a year and prune the website every few months, ruthlessly.
6. Check both on a phone, and ask one or two trusted illustrators for a blunt opinion.

The format is not the deciding factor. Clear work, chosen for the person in front of you and delivered without friction, is what gets the reply. Pick the tool that makes that easier for the client — and keep it tidy enough that you are not embarrassed to send it.
