Insert Image Into PDF
You do not need Acrobat Pro to drop a signature, a letterhead logo or a QR code onto a PDF page. This tool lets you pick the page, upload a PNG/JPG and drag it into position, the output is a new PDF with the image embedded, no rasterisation of the original pages.
How to insert an image into a PDF
-
1
Upload the PDF
Your original document.
-
2
Upload the image
PNG (with transparency) or JPG.
-
3
Choose the page
Any single page, or "all pages" for a stamp effect.
-
4
Position and resize
Drag within the page preview; the original PDF content stays untouched underneath.
-
5
Export
Download the modified PDF with the image layered on top.
What gets embedded
The image is added as a new PDF object and referenced from the page’s content stream. That means:
- Original page content is preserved, no “flatten to raster” step.
- PDF text remains selectable and searchable through the image (unless the image fully covers text).
- File size grows by roughly the image’s file size, a 300 KB signature adds ~300 KB to the PDF.
When to use a transparent PNG
Signatures, round stamps and logos with a non-rectangular outline need PNG with alpha. A JPG of the same signature will drop the white paper background onto your document.
Positioning conventions
PDF coordinates originate at the bottom-left of the page, not the top-left. This tool hides that detail, you drag the image visually in preview, but if you script PDFs elsewhere, remember the flipped Y axis.
Safe use cases
- Signatures on contracts. Consider a proper e-signature service (DocuSign, HelloSign) for legal agreements that need an audit trail.
- Stamps (“Paid”, “Draft”, “Confidential”).
- Watermarks: semi-transparent logos across every page.
- Letterhead: brand elements on the first page only.
Caveats
- Some heavily encrypted or XFA-form PDFs cannot be modified without flattening; this tool will flag those cases.
- Scanned PDFs where every page is already an image get the new image layered on top, but there is no underlying text to preserve.
Frequently Asked Questions
No. The tool adds the image as a new object on top of the existing page; selectable text and form fields elsewhere on the page remain functional.
Yes, pick “all pages”. This is the typical workflow for a corporate letterhead or a “Draft” stamp.
It produces a visible image on the PDF but no cryptographic audit trail. It can also invalidate an existing digital signature because the document changes. For legally enforceable e-signatures use a dedicated service (DocuSign, Adobe Sign) that records identity verification and timestamps.
No. The PDF, image and modified PDF stay in your browser. In the multi-step flow, a local working copy expires after 30 minutes and Start over deletes it immediately. PDFs are limited to 100 MiB; PNG and JPEG images to 20 MiB and 40 megapixels.
