Frequently asked questions
- Will the background hide my text?
- No — the background is drawn behind your existing content, so text and graphics stay on top. Note that pages with their own opaque white background will cover the color you add.
- Can I use an image instead of a color?
- Yes. Pick a PNG or JPG and it's placed full-bleed behind each page — useful for branded stationery or textured paper.
- Does my file get uploaded?
- No. The background is composited entirely in your browser — nothing is sent to a server.
Color or image, behind your content
A background can turn a plain document into branded stationery or make slides easier on the eyes. Add Background places a solid color or a full-page image behind every page, under your existing text and graphics, so nothing you already have is covered up.
Solid colors and full-bleed images
Pick any color with the color picker, or choose a PNG or JPG to stretch edge to edge behind each page. It's a quick way to add a tint, a letterhead texture, or a consistent brand backdrop across a whole document.
Notes and limits
Because the background sits underneath, a page that already paints its own solid white will hide the color — that's expected. Everything runs locally, so nothing is uploaded. To place a smaller image on top of the content instead, use Add Image.
How it composites onto the page
The background is drawn as the very first element on each page, before anything else in the original content stream is redrawn on top — that's the technical reason it can never obscure existing text or graphics, and also why a page with its own opaque white fill will hide it, since the original content still wins that layer. Color fills use the exact color value you pick; image fills are stretched or cropped to cover the full page edge to edge.
Common real uses
Printing invitations or certificates on plain paper without buying pre-printed stationery, giving an internal report a light brand tint without redesigning it, adding a subtle texture behind scanned handwriting notes to make them easier to read on screen, or matching a PDF to a company's letterhead color for a batch of otherwise unbranded documents.
A print cost consideration
A full-page solid color or image background uses far more ink or toner than plain text on white paper — fine for a one-off certificate, worth reconsidering for a hundred-page report someone's going to print at their own expense.
