The PDF is the imposed object. The cover is a plate.
A lookbook lives as a PDF because the printer, the tutor and the client still open that container. The homepage does not. Dragging the whole volume onto a landing page is how you ship a 40 MB brick and a first paint that never comes.
Pdfmira treats the volume as a sheet to develop: each page can leave as WebP, JPG or PNG. The WebP cover is the newsprint of 2026 — handsome enough on a retina screen, thin enough for a portfolio grid. It is not a press master. Keep the PDF for the copy shop.
A sequence that respects the spread
Start from the PDF you already signed off, not from a folder of leftovers. On PDF to WebP, leave the file on the light table and watch the plate before you download. If type breaks or skin posters, the source was already thin — WebP will not invent a drum scan.
Need a still that a campus printer or an old form will open? Run the same page through PDF to JPG at print stock. Need the cover on a site and a JPG in the press kit? Two jobs, two plates. Do not flatten a twelve-page signature into one hero if the story is a sequence: export pages, then pick the three that read at thumbnail size.
If the lookbook is already a folder of JPGs, skip the PDF hop. JPG to WebP is the shorter cut. The PDF route is for when the only master you have is the imposed file.
Weight, not magic
WebP is a publishing format. Offset, plotter, and most photo labs still want JPG or PNG. If a call asks for “cover 300 dpi TIFF”, this spread will not save you: you need the original plates.
After the WebP exists, Compress images can still shave bytes for an LMS that caps 2 MB. Judge the large preview. If the magenta of a lookbook dress turns to dust, raise the stock or stay on the heavier file. Pdfmira does not run an imposing engine: we rasterise, we do not rebuild a grid.
What this is not
This is not a substitute for the tool that imposed the lookbook. Fonts, bleed and crop marks stay in the PDF. The WebP is a picture of a page, for the wall and the web. Guest flow is enough for the first export; a named studio is for the roll of jobs, not for quality.
