Adding an image to an existing PDF document often feels frustrating when PDF software forces you to convert the entire file to Word first or upload private documents to an unknown server. TryDocsy Add Image to PDF inserts graphics directly onto existing pages in your web browser. You can place color photographs, transparent corporate logos, diagram callouts, or scanned payment receipts onto invoices, proposals, and application forms without converting or re-rendering surrounding text.

The tool runs in your browser, so your contracts and financial records stay on your machine. To change the text as well, see [the methods that edit existing PDF text](https://trydocsy.com/blog/how-to-edit-a-pdf). If you need to sign a contract, use [Sign PDF](https://trydocsy.com/pdf/sign) to draw or upload a signature. If you want a repetitive background mark across every page, use [Watermark PDF](https://trydocsy.com/pdf/watermark) instead.

## How it works

1. **Open your PDF document** — Drop your PDF file into the editor area or choose it from your local disk. The document opens in browser memory without sending bytes across a network.
2. **Upload your image file** — The Add image dialog opens on its Upload tab once the PDF loads. Pick a PNG, JPG, or WEBP image from your device, then choose Add to page. Reopen the dialog from the Add image or signature button in the toolbar.
3. **Adjust position and dimensions** — Drag the image across the page to position it. Use its resize handle to change the size, which keeps the proportions.
4. **Save and download the updated PDF** — Check the page, click Download in the upper bar, and save the modified PDF file to your computer.

## When you'd use it

- **Company letterheads and organizational logos** — Place transparent PNG branding logos and official organization crests onto sales invoices, white papers, and formal proposal sheets.
- **Expense reimbursement and receipt vouchers** — Attach scanned receipts, train tickets, and hotel invoices onto corporate travel expense forms for monthly accounting verification.
- **Identity photos on job and registration forms** — Add passport-style portrait photos onto submitted employment applications, membership profiles, and conference registration records.
- **Technical diagrams and workflow charts** — Insert updated architecture sketches, schematic diagrams, and data screenshots into existing specification guides and system documentation.

## How does default image sizing and positioning work?

A new image starts at 28% of the page width, centered horizontally in the upper part of the page. Its height is capped at 40% of the page height and its width at 90% of the page width, so a tall portrait or a wide banner still fits.

Once placed, you can drag the image to any location on the page or pull its resize handle to enlarge or shrink it. The handle keeps the image's proportions, so photos do not stretch. If you need to make corrections to existing wording near your image, you can switch to [Edit PDF](https://trydocsy.com/pdf/edit) to adjust text runs.

## How do PNG and JPEG images affect exported PDF file size?

A PDF stores each image as its own object. A JPEG goes in with its original compressed bytes, so its quality doesn't change. A PNG is decoded and compressed again without loss, and its transparency is kept as a separate soft mask, so a PNG's cost in the PDF can differ from its size on disk. Phone photos with a rotation flag are the exception to the JPEG rule: PDF ignores that flag, so we re-encode those upright as a new JPEG.

In our test, on a synthetic 1,909-byte two-page PDF, a 778 KB JPEG photo added about 779 KB, and a 512 by 512 pixel transparent PNG of 215 KB added about 222 KB. The picture's pixel size on the page made no difference, since resizing it in the editor doesn't change the stored image. To keep a PDF small for email, shrink your images before placing them, or run the finished file through [Compress PDF](https://trydocsy.com/pdf/compress).

## What image formats and embedding features were tested?

We tested placement on a synthetic two-page PDF using Microsoft Edge 156 on Windows 11. Each image was placed, the PDF was downloaded, and the file was reopened to check the stored image and the page text.

We read the files back with pdf.js and pdf-lib, and did not open them in Acrobat or Preview, so check the result in your own reader before you send it.

*Synthetic document image tests, Microsoft Edge 156 on Windows 11, 2026-10-31*

| Image | How it's stored | Result |
|---|---|---|
| PNG with transparency | Lossless, with a soft mask | Soft mask present, page text unchanged |
| JPEG photo | Its original bytes | Stored as JPEG, page text unchanged |
| JPEG with a rotation flag | Re-encoded upright | Stored at its upright size |
| WEBP image | Converted to PNG | Stored as an image, page text unchanged |

## Frequently asked questions

**Q: What image file formats can I add to a PDF?**
A: You can add PNG, JPEG, JPG, and WEBP image files. Transparent PNG images keep their transparency, so text and colors underneath stay visible around your graphic.

**Q: Why does my PDF become larger after adding an image?**
A: A PDF stores the full image data of each picture you add, even if you shrink it on the page. Expect the PDF to grow by about the size of a JPEG. A PNG is compressed again, so its share can come out a little higher or lower than the file you started with.

**Q: Can I resize or move the image after placing it?**
A: Yes. Click the placed image to select it. Drag it to move the picture anywhere on the page, or pull its resize handle to make it larger or smaller.

**Q: Does adding an image alter or flatten the original PDF text?**
A: No. An image is added on top of the existing page content. The text under and around it stays in the file and is still searchable, even where the image covers it.

**Q: Can I add multiple images to the same page or across different pages?**
A: Yes. You can place multiple distinct images on one page or navigate between different pages in the document to insert images wherever needed before saving your final file.
