Insert a picture into a PDF in 4 steps
- 1
Open Add Image
Go to Add Image and select the PDF. The Image tool is active and the side panel reads "Click on the page where the image should go."
- 2
Click the page and pick a file
Click the spot where the top-left corner of the image should sit. Your file picker opens; choose a PNG, JPG, WebP or GIF up to 25 MB.
- 3
Resize and position it
The image arrives selected. Drag it to move it and drag a corner to resize. Keep aspect ratio is on by default; untick it if you really want to stretch the picture. Lower Opacity to make a faint stamp or background.
- 4
Save PDF
Click Image again to place another picture, or click Save PDF. The download ends in -image.pdf.
How big the image appears at first
The tool treats each pixel as 1/96 inch, so a 300-pixel-wide logo starts about 3.1 inches (225 points) wide. Large photos are scaled down so they never start wider than 60% of the page. Resizing afterwards does not touch the pixels; it only changes how large they are drawn.
Which image format to use
- PNG for logos, signatures and stamps. It is embedded as-is, and transparent areas stay transparent, so the page shows through.
- JPG for photos. It is embedded without re-compression, so there is no extra quality loss. A JPG that a phone saved with a rotation flag is re-encoded upright first, because PDF viewers ignore that flag and would show it sideways.
- WebP and GIF are accepted and converted to PNG on the way in. An animated GIF becomes a still image.
- HEIC, SVG and TIFF cannot be picked here. Convert them first, or turn an SVG into its own page with SVG to PDF.
Adding a signature image or logo
For a scanned signature, crop it tightly and save it as a transparent PNG so no white rectangle covers the signature line. If you want a tool built for signing, with the signature placed and sized for you, use Upload Signature. To put the same logo on every page, Add Watermark saves you from placing it page by page.
Add Image vs. JPG to PDF
Add Image puts a picture onto a page that already exists. If you want each photo to become its own new page, that is a conversion job: use JPG to PDF or Images to PDF. You can then add those pages to an existing file with Merge PDF.
Frequently asked questions
Will adding a photo make my PDF much bigger?
The file grows by roughly the size of the image file, since it is embedded at full resolution. If the result is too large, run it through Compress PDF.
Can I put an image behind the existing text?
No. Added images are always drawn on top of the original page content. Lower the opacity if the text underneath must stay readable.
Can I use the same image twice?
Yes. Select it and click the duplicate button in the side panel, then drag the copy into place. The image data is stored only once in the saved file.
Can I replace an image that is already in the PDF?
Not directly. Cover the old image with a Whiteout box and place the new one on top.
