How to Use Add Background

Adding Backgrounds to PDFs

So you need to add a background to a PDF. Maybe for branding, maybe to make it look less boring, maybe you just want a watermark on there. Whatever the reason, here's how to do it without installing Acrobat or whatever expensive thing Adobe is selling these days.

The tool lets you use solid colors, gradients, patterns, images, watermarks - pretty much anything you want behind your text. And yeah, your original content stays readable. Nobody wants a background that makes the text impossible to see.

Upload Your File

  • Find the upload button. Click it. Pick your PDF.
  • It reads the file and tells you how many pages are in there. Just so you know what you're working with.

Pick What Kind of Background

  • There's presets if you're in a hurry. Professional stuff, creative stuff, business templates. Click one and you're done.
  • Or go custom if you want something specific. Colors, gradients, patterns, your own image, text watermarks. Your call.

Customize It

  • Solid Color: Pick a color. Adjust how see-through it is. That's it.
  • Gradient: Linear, radial, angular - basically different ways to blend colors. Add multiple colors if you want. Change the angle until it looks right.
  • Pattern: Dots, lines, grids, diagonal lines, crosses. Size them however you want. Match your brand colors or whatever.
  • Image: Upload your logo or any image. It'll fit it on the page. You can rotate it, flip it, make it more transparent. Had to use this last month for company letterhead.
  • Watermark: Type "CONFIDENTIAL" or "DRAFT" or whatever you need. Pick the font size, color, angle, how faded it looks.

Which Pages Get the Background

  • You can set start and end pages. Don't want it on every page? Fine.
  • Skip the first page if you want your cover clean. Skip the last page too if needed.
  • Only odd pages, only even pages - useful for printing two-sided stuff.

Preview and Download

  • There's a preview on the right side. Shows you what it'll look like before you commit.
  • Tweak colors, opacity, position - whatever needs fixing.
  • Hit download when you're happy with it. Takes a few seconds to process.
  • File downloads with "with-background" in the name so you know which version it is.

Other Stuff:

  • Files get deleted: Your PDF gets wiped from the server after 2 hours. Or you can delete it right away if you're paranoid. I usually just let it auto-delete.
  • Pretty easy to use: Interface isn't complicated. Live preview shows changes as you make them. Processing is fast.
  • Keeps your content intact: Background goes behind everything. Your text stays readable, images stay visible. Quality doesn't get trashed.

That's basically it. Upload, pick a background style, download. Works for business docs, reports, whatever you need to brand or watermark.
