I have these PDF files and they are 4500px x 6646px and 300 resolution and I need to display it on a touchscreen....on this touchscreen you have the ability to zoom in and zoom out. I have converted the PDF to png and when I display it on the touchscreen it looks a little blurry / pixelated when not zoomed in, but when I zoom it its clear as day. My question what size or format would look best on touchscreen that is 1920 x 1080 resolution? So it looks clear as day both zoomed in or zoomed out? I have tried svg same result....I have access to inDesign, Illustrator and Photoshop.....Does anyone have any suggestions?

I have tried using Inkscape, but it does not work well on Macs.

PS - The PDFs are one site plan and bunch for floor plans.

  • Why can't you use the PDFs? Have you tried SVG?

    There's no step by step: open in Illustrator and save as SVG. Are there raster images in the PDF or is everything vector?

  • As mentioned above – the optimal solution would probably be to save as SVG from Illustrator if that is possible. If you need to use PNG and the problem is that it looks fuzzy in 100% view after exporting from Illustrator, I would try to open the PDF in Photoshop rather than Illustrator, and "Save as ..." (or Export) to PNG from there. I have found that not all Adobe programs handle export to raster images very well.

Adobe Illustrator, Adobe InDesign both handle vector art, so does Sketch app (though it's more of a UI design tool now), so do Affinity Designer and Affinity Publisher - all of which are available for Mac - I also use Inkscape (on occasion) on a Mac, and as long as you've an X11 instance, it works fine.

For myself, I'd do this work in Affinity Designer myself.

I'd plan on using .svgs as your display art format, as it allows scaling / zooming without any resolution or pixelization issues, assuming all vector content.

If you do have raster art embedded in that .pdf, I'd redraw it as sheer vector - that way your .svg won't have any raster content to get pixelated.

Hope that helps.
