Opening a PDF as an editable layout in Layout by Zaweba
Layout by Zaweba opens a PDF as a real layout with text frames, fonts, colours and spacing, plus vector shapes and pictures you can edit again.

Sometimes the PDF is all that is left. The designer who made last year's brochure has moved on, the original files are lost, or a supplier only ever sends PDFs. Layout by Zaweba can open a PDF as a layout, so the pages come back as frames, shapes and pictures you can work with again, instead of a flat document you can only annotate.
What comes across when a PDF opens
Text becomes text frames, with fonts, sizes, colours, spacing and alignment carried across. Vector shapes become shapes you can select, recolour and reshape. Pictures come across as pictures in frames.
That is different from placing a PDF page, which puts the whole page into a frame as a picture. Placing keeps the page exactly as it was but doesn't let you change it. Opening rebuilds it as a layout you can edit.
Jobs this makes possible
Updating an old document is the obvious one. A price list, a menu or a programme from last year needs new dates and a few new items. Open the old PDF, change what needs changing and export again, rather than rebuilding from nothing.
Reusing parts of a supplied file is another. An advert, a logo panel or a chart from a PDF can be opened, then the pieces copied into your own document as editable objects.
Translating or localising a leaflet goes more smoothly when the text is in frames with its formatting, so a translator's text can replace the original paragraph by paragraph.
Checking how a file was built can help too. Opening a PDF shows how the text is broken into frames and how shapes are layered, which is useful when you need to match a style.
What to expect and how to tidy up
A PDF is a finished output, not a working file, so the layout you get back reflects how the PDF was written. Text that ran in one long story in the original may come back as separate frames, perhaps one per line or per paragraph, because a PDF doesn't keep the threading. Styles aren't in a PDF either, so the text arrives with its formatting applied directly.
That means a little tidying is normal. Join frames that should be one story by threading them, define paragraph styles from the text as it came in and apply them, and replace low quality pictures with originals if you have them. The Links panel will show what picture files you're working with.
Fonts matter. The PDF tells Layout which fonts were used; if those fonts aren't on your PC, the text is shown with a substitute and preflight flags the missing font. Install the fonts, or choose replacements, before you edit text in earnest, or line breaks will change when you fix it later.
Mistakes to avoid with opened PDFs
Expecting a perfect working file is the main one. You get an editable layout that looks like the PDF, not the designer's original file with all its structure. Budget some time to tidy it.
Editing text before sorting out fonts leads to reflow surprises later.
Forgetting rights is another. Opening a PDF makes its contents editable, but it doesn't change who owns them. Use this on documents you have the right to change.
Where opening a PDF fits in Layout
Once the pages are open, every other tool applies. Styles bring consistency back, preflight checks the result, and the export presets produce a fresh print PDF, an EPUB or a set of slides. For many small jobs, opening last year's PDF is the fastest route to this year's document.
