Add Images to an Existing PDF – Append Image Pages Free Online

Use the free Add Images to a PDF below: your PDF never leaves your browser — all work happens on your device, and nothing is uploaded to any server.

What this tool does

Adding a photo to the end of a PDF sounds simple, yet most free tools make it hard. They ask you to sign up, they shrink your image, or they send your file to a server you do not control. This tool takes a different path. You open your PDF in your browser, pick one or more images, and each image becomes a full new page at the end of your document. The original pages stay exactly as they were. Nothing is reordered, nothing is compressed by a remote service, and nothing leaves your device.

That matters when the PDF is personal. A scanned contract with a photo annex, a school report that needs a diagram on the last page, or a portfolio that gains a new piece of work — these are files you may not want to upload. Because all the work happens locally with the pdf-lib library running in your browser, your file is never sent anywhere. When you press download, the new PDF is built on your own computer.

How to use it

Start by choosing your PDF file. Then choose your images. JPG and PNG both work. If you pick several images, they are added in the order you selected them, one per page. Each new page is sized to fit the image, so a wide photo gets a wide page and a tall photo gets a tall page, up to a sensible maximum. Press the button and the finished PDF downloads at once. Open it to check that the new pages sit exactly where you expect them — right after the last original page.

If an image looks wrong, check its orientation before you add it. The tool keeps the image as it is, so a sideways photo stays sideways. Rotate it in your phone or photo app first, then add it. That one habit saves most people a second try.

When it is useful

Teachers use this pattern all the time. A worksheet PDF gains a scanned answer sheet, or a hand-drawn map, without rebuilding the whole document. Small businesses attach a photo of a signed delivery note to an invoice PDF. Job seekers add a certificate scan to the end of a CV PDF. Photographers append a contact sheet to a client proof. In each case the goal is the same: keep one document, in one order, instead of juggling two files.

It also helps with scanned paper. If you scanned a multi-page form but one page came out as a photo on your phone, you can join it to the PDF in seconds. No printer, no scanner software, no new account.

Tips for good results

Use clear, well-lit images. A dark or blurry photo will still be added, but it will look dark or blurry in the PDF too — the tool does not enhance images. Keep file sizes reasonable. Phone photos of several megabytes work fine, but a dozen huge photos make a very large PDF that is slow to email. If you only need the image for reference, a smaller copy is enough.

For documents you plan to print, PNG keeps sharp lines and text crisp, while JPG is smaller for photos. Both are accepted, so pick the format that matches your image. And always keep your original PDF. The tool creates a new file; it never overwrites the one you uploaded.

Limits you should know

This tool appends images at the end only. It does not insert an image in the middle of a document, and it does not place a small image inside an existing page. Those are different jobs with different tools. It also does not edit the text of your PDF. If you need to change wording, use a PDF editor instead.

Very large PDFs with hundreds of pages may be slow on an old phone, because the whole file is rebuilt in the browser. On a normal desktop or a recent phone, a typical document finishes in seconds.

Privacy, in plain words

Your PDF and your images are processed on your device. They are not uploaded, stored, or seen by anyone else. Close the tab and the files are gone from the tool. That is the whole privacy story, and it is the reason this tool is safe for personal documents.

Common questions

Can I add many images at once? Yes. Select several files in one go and each becomes its own page, in selection order.

Will my original pages change? No. They are copied untouched, and the new pages are added after them.

Does it work on mobile? Yes, in any modern mobile browser. Pick files from your photo library and download the result.

Is there a file size limit? There is no server limit, because there is no server. Your browser memory is the only practical limit, so extremely large files may struggle on low-memory devices.
