I have yet to find anything that works well. I can't afford Adobe Acrobat, and get awful migraines from Adobe Reader. Nearest I've found is to go into Textedit and see if I can move optional content groups to a hide list. But that only rarely works.

For scanned pdfs, I currently use k2pdfopt with options to clean up, convert jpeg2000 to jpeg, etc., and ocrmypdf with various options to ocr the pdf. The default k2pdfopt settings chop pages up for small Kindles, but -mode copy avoids that, and device, color handling, etc. settings can help create fast-loading and readable pdfs. I used to use Elucidate to ocr the pdf. For other pdfs, I haven't found a good solution. Does Pdf Expert allow users to remove a given layer (not merge it into the rest of the pdf, but remove as in remove), or change OCProperties (the setting to show or hide a layer by default)? It's possible that the right OCProperties might keep k2pdfopt or other processing tools from passing that layer through, so that older devices can show the pdf without the extra graphics obscuring everything.

I've tried Acrobat Reader, it gives me migraines. I don't have and can't afford Acrobat Pro.

I'm trying to convert fancy pdfs into more-readable pdfs. Many of these fancy pdfs have colorful backgrounds which obscure the text. I'm trying to remove the colorful backgrounds for clarity and reprocess everything to pdf 1.4 for compatibility and speed. Exporting like that would convert the pdfs into many image files each, lose the searchable text, and keep the colorful backgrounds.

Same problem, but Inkscape will only open one pdf page at a time. I need to repair whole books. Besides switching fonts, Affinity Publisher turns some italic text into regular text, and adds spaces in the middle of words.

Hi, A lot of publishers publish ebooks as complicated pdfs. If I've bought a pdf or downloaded a free pdf, I often need to pre-process it before I can read it on my Mac or on my Kindle. For scanned ones, and simple pdf-born ones I've had a lot of success with Willus's k2pdfopt. But for complex pdf-born-pdfs, I'm often at a loss. Would Affinity Publisher or one of its companion apps help? A lot of pdfs include fancy background images which obscure text. Being able to hide layers and export the results sounds handy, though from the demo, it looks like Affinity Publisher requires me to select the same layers on each page. Ideally, I'd like some way to check all the layers in the pdf, select which ones to hide, and maybe then make exceptions for specific pages. I can't figure out how, is it possible to do that? I think I saw a feature request, so maybe it isn't yet, but will be possible...? A lot of pdfs also include very faint text on some pages, or light text against dark backgrounds, or dark text against dark backgrounds. If I can edit layers to hide the backgrounds, is it possible to switch all text to black?
