How to add an image to a PDF

Placing an image, step by step

1. Open the Add Image tool.
2. Select your PDF first, then the image you want to drop in, a PNG or JPG.
3. List the pages the image should appear on.
4. Pick one of nine positions and set the width as a percentage of the page.
5. Press Add image and download the updated PDF.

Choosing PNG or JPG

PNG and JPG are the two formats a PDF can embed directly, and the choice is not arbitrary. Use PNG for logos, seals, stamps and anything with a transparent background: the transparency is preserved, so the mark sits cleanly on top of your existing content instead of arriving inside an ugly white rectangle. Use JPG for photographs, where its compression keeps the file small and the missing transparency doesn't matter. Other formats (WebP, GIF, SVG) need converting first, which any image viewer or editor can do by re-saving as PNG.

Sizing and placement without distortion

You control the image by its width, expressed as a share of the page width, and the height follows automatically from the image's own aspect ratio. That single-dimension approach is deliberate: it makes it impossible to stretch or squash the picture, because you never set width and height independently. The nine positions (four corners, four edge midpoints and the center) each hold a consistent margin, so a logo pinned to the top-right lands in the same relative spot on every page you target, whatever their sizes.

How the image is embedded

Technically, the picture is stored once as an image XObject and drawn onto each page you selected at the coordinates your position and width imply. That is efficient (the same logo added to twenty pages is not twenty separate copies of the pixels) and it means the image becomes a true part of the page content, visible in every reader and every printout rather than living in a detachable annotation layer that other software might strip.

Where it earns its keep

Three jobs cover most uses. Branding: stamp a company logo in the corner of a report or across an invoice template so every page carries your identity. Signing and sealing: drop a scanned signature or an official seal onto the exact page of a contract that needs it, without printing and rescanning the whole document. Filling visual forms: place a passport photo, a product shot or a floor-plan image into the slot a template leaves for it. For the reverse task, pulling pictures back out of a PDF, use Extract Images.

Both files stay on your device

The image is embedded into the PDF by code that runs in your browser, so neither the document nor the picture (a signature, a company seal, a personal photo) is ever uploaded to a server. Everything is assembled locally and handed straight back to you as a download. That matters most precisely when the image is something you would not want floating around online; the reasoning behind that guarantee is spelled out in are online PDF tools safe.

Frequently asked questions

Will my logo keep its transparency? Yes, if it is a PNG with transparent pixels. JPGs have no transparency and will show a solid background.

Can I add several different images at once? One image per pass. To stack a second one, run the tool again on the file you just downloaded; doing them one at a time keeps positioning predictable.

Can I put the same logo on every page? Yes. List every page (or a range), and the image is placed identically on each in a single pass.

Does the placed image print? Yes. It is drawn into the page content, so it appears in every reader and on paper. It is not a hideable annotation.

What if I only need typed words, not a picture? Use Add Text for selectable labels and dates, or Watermark for a repeated stamp across pages.
