How to convert add image to PDF
- Open the PDF invoice, quote, or report that needs visual branding or verification.
- Pick your image file in PNG, JPG, WebP, or GIF format from your local workplace drive.
- Move the graphic over the desired page area and drag the corner handle to resize it.
- Select "Download PDF" to export a professional document containing your placed graphics.
Company logos, accounting stamps, and transparent graphic placement
Adding a corporate emblem to a supplier estimate or stamping "PAID" across a settled billing statement makes office documents look professional. The tool accepts PNG, JPG, WebP, and GIF images (displaying the first frame of animated files), placing newly chosen pictures in the middle of your active page view at half page width or less. Transparent backgrounds in PNG files are preserved, enabling circular department seals and signature images to sit cleanly over text and table grids without ugly white backing boxes.
For building inspection logs, property condition inventories, and insurance assessments, photographic evidence in JPG format is embedded in its native state without lossy re-compression. Your office photos and confidential company assets are never transferred over the web, as pdf.js and pdf-lib manage image rendering and document synthesis entirely on your desktop computer. The tool also handles sideways scan pages correctly, ensuring that pictures land where you positioned them on screen.
Precise placement on invoices, proportional scaling, and reliable printing
Desk workers can position graphics with great accuracy by dragging the picture across the page, or by using keyboard arrow keys to nudge the item into place (holding Shift for 10 pt steps). Corner control handles let you resize images while preserving their natural aspect ratio, preventing distorted logos or squished inspection photos. If you need to enclose an image or table within a visible boundary, switch to "Box" to add an outline in Thin, Medium, or Thick stroke widths.
Clicking "Download PDF" embeds your pictures into the document fundamental graphic stream. Unlike temporary viewer comments that can fail to print, embedded images become permanent elements of the page that show up consistently on client tablets, mobile readers, and office laser printers. The resulting file downloads as <original name>-edited.pdf, keeping your master paperwork untouched. To stamp the same mark on every page in one go, Watermark PDF does that job.
Questions
Can I insert a company logo with a transparent background onto an invoice?
Yes. The tool retains transparency in PNG graphics, so your logo overlays colored backgrounds and invoices cleanly without a white bounding box.
How do I resize a stamp image without distorting its proportions?
Drag the corner handle of the placed graphic. The editor locks the aspect ratio automatically to prevent stretching or skewing.
Can I add a drawn signature to an office memo or quote?
Yes. You can switch to the "Sign" tool to draw an approval signature directly on screen, or import a pre-made transparent PNG signature.
