How to edit a PDF's layout when you have no source file

Open the PDF in Layout by Zaweba and it comes in as a layout rather than a flat picture. Text arrives in text frames with its fonts, sizes, colours, spacing and alignment, drawings arrive as vector shapes, and photographs arrive as pictures, so you can move things, change words, swap pictures and export a new PDF.

This is the answer to a very common problem: someone needs a leaflet updated, the designer who made it has moved on, and all that is left is the PDF. Redrawing it from scratch is slow. Opening it as a layout gets you most of the way in moments.

What comes across, and what to expect

A PDF is a finished print file, not a working document, so it doesn't contain everything the original layout did. Layout reads what is there and builds frames from it. Text keeps its look, but the PDF often stores text in short pieces, a line or a few words at a time, rather than as one flowing story. Shapes come across as vector paths you can edit. Pictures come across at the resolution they were saved at in the PDF, which may be lower than the originals.

That means small edits, such as a new phone number, an updated date, a different photo or a moved logo, are quick. Wholesale rewrites of long text are better done by joining the text into a proper story first or retyping it into a fresh frame.

Editing step by step

Open the PDF and save it straight away as a .zala document, so you are working on a copy and the original stays safe. Look over each page to see how the text has been split into frames. Make your word changes in place. If a paragraph needs to grow, it may be easier to delete the separate line frames and set the paragraph again in a single text frame with a paragraph style.

Check the fonts. If the PDF used fonts you don't have, live preflight's missing fonts check shows it, and missing-font substitution is highlighted in the text, so you can choose a replacement deliberately rather than by accident.

Replace pictures where you have better versions. The Links panel shows each picture's effective and actual resolution, which tells you quickly whether a picture taken out of the PDF is good enough for print or needs replacing with the original.

Rebuilding for the long term

If the document will be updated regularly, it pays to rebuild it properly once. Create paragraph styles for the headings and body text, apply them, and thread the text into stories so it flows. Make a parent page for the repeating parts such as page numbers and footers. After that, future updates are as easy as with any document made in Layout from the start.

Exporting the new version

When the changes are done, run live preflight and export with the preset that suits the job: a press preset for a printer, Smallest file for email, or one of the PDF/X-style presets if the printer asked for one. If the result needs to meet a standard, File > Check a PDF can check it against PDF/X, PDF/A-2b and PDF/UA rules.

Knowing the limits

Some PDFs are harder than others. A scanned document is a picture of a page, so there is no text to edit, only an image. PDFs with heavily outlined text or complex transparency may come in as many small pieces. And a file someone else created may be theirs to control, so make sure you have the right to change it before you start.

For the everyday job of updating a leaflet, a menu, a form or a poster when the source has gone missing, opening the PDF as a layout is the fastest honest route back to an editable document.
