The fastest way depends on what you already have open

If you have a PDF file and want to insert photos into it, your options split into three paths: using the PDF editor you already chose, converting the PDF to a format you can edit in a word processor, or using a dedicated online tool. The method that works fastest for you depends on whether you're on a computer or phone, how many photos you're adding, and whether you need the result to stay as a PDF or can work in another format.

Most people's first instinct — opening the PDF in Adobe Reader or Preview and looking for an "insert image" button — won't work, because those programs are viewers, not editors. You need either an editor you installed, or a web tool you can reach from a browser.

Key Takeaways

  • PDF editors like Adobe Acrobat, PDFtk, or Sejda let you insert photos directly into a PDF, but most require either a paid subscription or an account.
  • Converting a PDF to Word, adding photos there, and saving back to PDF works with free tools like LibreOffice but produces a less reliable result.
  • Online tools like Smallpdf or ILovePDF let you upload a PDF and add images without installing software, though they store your file on their servers temporarily.
  • On phones and tablets, the easiest route is usually a dedicated app like Adobe Acrobat Reader (paid features) or Preview on Mac, rather than trying to edit in a browser.
  • Where you add the photo matters: inserting it as an image object keeps the PDF structure intact, while converting and re-saving can shift text and formatting.

Adding photos directly in a PDF editor on Windows

If you chose Adobe Acrobat (the paid version, not the free Reader), open your PDF, go to the Tools menu, select "Edit PDF," then look for "Add Image" in the toolbar. Click where you want the photo, navigate to the file on your computer, and it will appear in the PDF. You can resize it by dragging the corners. Adobe Acrobat costs about $15 per month or $180 per year, depending on whether you bundle it with other Creative Cloud apps.

If you don't have Adobe, PDFtk is a free command-line tool that works on Windows, but it requires typing commands rather than clicking buttons — not ideal if you're not comfortable with a terminal. A more user-friendly free option is LibreOffice Draw, which is part of the free LibreOffice suite. Open your PDF in Draw, click Insert > Image, select your photo, and it will appear on the page. You can then save the file back as a PDF. The trade-off is that LibreOffice sometimes shifts text slightly when you re-save, so check the result before you rely on it.

Sejda is a web-based editor that works in any browser on Windows. Go to sejda.com, click "Edit PDF," upload your file, then use the "Add Image" button in the toolbar. You can add multiple photos, resize them, and arrange them on the page. Sejda's free tier allows two tasks per hour; beyond that, you pay per task or subscribe monthly. Your file is deleted from their servers after one hour.

Adding photos directly in a PDF editor on Mac

Mac's built-in Preview app can edit PDFs without installing anything else. Open your PDF in Preview, click the markup toolbar icon (it looks like a toolbox), then click the image icon and select "Sketch" or "Signature" — or use Insert > Image from the menu bar. Select your photo, and it will appear on the page. You can move and resize it with your mouse. This is the fastest route on Mac if you only need to add one or two photos.

If you have Adobe Acrobat on Mac, the process is the same as Windows: Tools > Edit PDF > Add Image. If you want a free alternative with more features than Preview, read LibreOffice (free, open-source), open your PDF in LibreOffice Draw, and follow the same Insert > Image steps as on Windows.

Sejda also works on Mac in any browser, with the same process as Windows: upload, click "Add Image," position your photos, and read the result.

Using online tools when you don't want to install software

ILovePDF (ilovepdf.com) and Smallpdf (smallpdf.com) both offer "Edit PDF" features in a browser. Upload your PDF, click the image icon, select your photo from your computer, and drag it to the position you want. Both tools let you add multiple images, resize them, and rotate them. ILovePDF's free tier allows two tasks per day; Smallpdf's free tier is limited to two tasks per day as well. Both delete your file after a few hours.

The advantage of online tools is that you don't install anything and don't need a subscription. The disadvantage is that your PDF and photos are temporarily stored on someone else's server. If your document contains sensitive information — medical records, financial statements, or anything you wouldn't want a third party to see — use an editor on your own computer instead.

A middle ground is PDFtk Server (pdftk.com), which is free and open-source. It runs on your own computer, so your files never leave your machine. It's command-line only, which means you type instructions rather than clicking buttons, so it's best for people comfortable with a terminal.

Adding photos on an iPhone or iPad

The easiest route on iOS is Adobe Acrobat Reader (free app, paid editing features). Open the app, tap the PDF you want to edit, tap the pencil icon to enter edit mode, then tap the "+" button and select "Image." Choose a photo from your camera roll, position it, and save. The free version lets you view and annotate PDFs; adding images requires a paid subscription (about $10 per month).

If you don't want to pay, GoodNotes (paid app, about $8 one-time) lets you import a PDF as a background and add images on top of it, then export the result as a PDF. Notability (paid app, about $12 one-time) works the same way. Both are designed for note-taking but work well for adding photos to PDFs.

A free alternative is to email the PDF to yourself, open it in the Mail app, take a screenshot of the page, add your photo in the Photos app using the markup tools, and email the result back to yourself. This is slower and produces a lower-quality result, but it costs nothing and doesn't require an app.

Adding photos on an Android phone or tablet

Adobe Acrobat Reader (free app, paid editing) works on Android the same way as iOS: open the PDF, tap edit, tap the "+" button, select "Image," and save. Editing features require a paid subscription.

Xodo (free app with optional paid features) lets you open a PDF, tap the drawing tools, and insert images. The free version includes basic editing; advanced features like OCR require a paid subscription. MuPDF (free app) is a lightweight viewer that also supports basic image insertion, though the interface is less polished than Xodo or Adobe.

If none of these feel right, you can also upload your PDF to Sejda or ILovePDF from your phone's browser, add images there, and read the result. The process is the same as on a computer, just smaller on your screen.

When to convert to Word instead of editing the PDF directly

If your PDF is mostly text and you need to add photos alongside that text, sometimes it's faster to convert the PDF to a Word document, add the photos there, and save back to PDF. This works well if the PDF has straightforward formatting — mostly just paragraphs and headings.

To convert, use a free tool like Zamzar (zamzar.com) or CloudConvert (cloudconvert.com): upload your PDF, select "Word" as the output format, and read the result. Open the Word file in Microsoft Word or free alternatives like LibreOffice Writer or Google Docs, click Insert > Pictures, select your photo, and position it. Then save the file as a PDF: File > Save As > PDF.

The catch is that PDFs don't always convert perfectly to Word. Text might shift, images in the original PDF might disappear, or formatting might break. Always check the converted document before you rely on it. If the original PDF has complex layouts, photos, or forms, this method usually produces worse results than editing the PDF directly.

What happens to file size and quality when you add photos

When you insert a photo into a PDF, the file size grows by roughly the size of the photo itself. A typical smartphone photo is 2 to 5 megabytes; a PDF with one photo added will be roughly that much larger. If you're adding many photos, the file can become slow to open or difficult to email.

Most PDF editors let you compress images before inserting them. In Adobe Acrobat, right-click the image and select "Compress Image." In LibreOffice Draw, right-click and look for "Compress" or "Properties." Compressing reduces file size but also reduces quality — the photo will look slightly softer or grainier. For documents you're printing or sharing, this trade-off is usually worth it. For documents you're archiving, keep the original uncompressed version.

If you're adding a photo that's larger than the page, most editors will automatically shrink it to fit. Check the result to make sure the photo is still readable at the smaller size.

Frequently Asked Questions

Can I add a photo to a PDF without converting it to another format?

Yes, if you use a PDF editor like Adobe Acrobat, LibreOffice Draw, or an online tool like Sejda or ILovePDF. These insert the photo as an image object within the PDF structure, so the file stays as a PDF. Viewers like Adobe Reader or Preview cannot add images — you need an editor.

What's the difference between inserting a photo and scanning a document with a photo in it?

Inserting a photo adds an image file to an existing PDF. Scanning creates a new PDF from a physical document. If you have a printed document with a photo and want to digitize it, use a scanner app like Adobe Scan or your phone's built-in scanner, not an image insertion tool.

If I add a photo to a PDF and then open it in a different program, will the photo still be there?

Usually yes, as long as the program can read PDFs. The photo becomes part of the PDF file itself. However, if you convert the PDF to another format (like Word) and back to PDF, the photo might shift position or the conversion might fail. Stick with PDF editors to avoid this.

Does adding a photo to a PDF make it harder to search or copy text from?

No. Adding an image object to a PDF doesn't affect the text layer underneath. You can still search for words and copy text normally. The only exception is if you insert the photo as a scanned image (a picture of text rather than actual text), which makes that part of the document unsearchable.

Is it safe to upload my PDF to an online tool like Sejda or ILovePDF?

Both tools delete files after a few hours and use encryption in transit. However, your file does sit on their servers temporarily. If your PDF contains sensitive information like medical records, financial statements, or personal identification, use an editor on your own computer instead. For general documents, online tools are reasonably safe.
