How to Add Images to a PDF for Free (2026 Guide)
Dropping an image into a PDF sounds like it should be trivial — and it is, once you know where to click. The catch is that a PDF isn't a Word document: there's no cursor to type beside, so an image gets placed as a floating layer on top of the page. This guide shows you how to add a logo, signature, photo, or screenshot to any PDF for free, how to get the size and sharpness right, and how to avoid the handful of mistakes that make an inserted image look off.
When You'd Add an Image to a PDF
People reach for this far more often than you'd expect, usually for one of these reasons:
- Branding a document — dropping a company logo onto a quote, invoice, or report
- Signing by image — pasting a saved signature graphic where a contract needs one
- Completing a form — adding a passport photo or ID image to an application
- Annotating visually — placing a screenshot, diagram, or chart next to the text it explains
- Stamping — applying an "Approved", "Paid", or "Draft" graphic
If your goal is instead to turn a folder of photos into a brand-new PDF, that's a different job — see how to convert images to PDF. This guide is about placing images onto an existing document.
Which Image Formats Work — and Which to Pick
Most everyday formats are supported, but the right choice depends on what you're adding:
- PNG — the best choice for logos, signatures, and icons because it supports a transparent background. The image sits cleanly on the page with no white box around it.
- JPG / JPEG — ideal for photographs and detailed images. Smaller file size than PNG, but no transparency, so a photo arrives as a solid rectangle.
- WebP — a modern format that keeps quality high at a smaller size; handy when the finished PDF needs to stay light for email.
- GIF — works for simple flat graphics, though only the first frame is placed (PDFs don't animate).
One rule of thumb: if the image has anything that should "float" over the page — a logo, a signature, a stamp — use a PNG with a transparent background. For a full-frame photo, JPG is usually the sensible pick.
How to Add an Image to a PDF: Step-by-Step
Step 1: Open your PDF
Go to EditPDFs.app and upload the document. It opens in the editor with page thumbnails down the side, so you can scroll to the exact page that needs the image before you place anything.
Step 2: Select the image tool
Choose the image tool from the toolbar. This switches the editor into insertion mode and prompts you to pick a file — nothing is added to the page until you choose one.
Step 3: Choose the image file
Pick the image from your device (or your phone's photo library on mobile). It drops onto the current page as a selectable object with handles around its edges — think of it as a sticker you can still move, not yet glued down.
Step 4: Position, resize, and rotate
Drag the image to where you want it. Pull a corner handle to resize while keeping the proportions locked (dragging a side handle can stretch it, which is what makes logos look squashed). If the tool offers a rotation handle, use it to straighten a tilted signature or angle a stamp.
Step 5: Export the finished PDF
Once placement looks right, download the document. The image is embedded into the page, so it travels with the file and displays the same way for whoever opens it next.

The most common complaint about images in PDFs is that they end up blurry or pixelated. That almost always comes down to resolution. A logo that looks crisp at 80 pixels wide on a website will look fuzzy when stretched across half a page. A few habits prevent it:
- Start bigger than you need. It's fine to shrink a large image down; it looks terrible to blow a small one up. Aim for an image at least as wide (in pixels) as the space it will fill on the page.
- Mind the file size. A 12-megapixel phone photo dropped into a PDF can balloon the file. If the document needs to stay email-friendly, resize the photo down first, or compress the PDF afterwards.
- Place images in whitespace. An inserted image sits on top of the existing content, so dropping it over text hides what's underneath. Position it in a margin or blank area unless covering something is the goal.
Troubleshooting Common Problems
The image has a white box around it
That's a JPG. JPGs can't store transparency, so the background fills in as white. Re-export the graphic as a PNG with a transparent background and re-add it — the box disappears.
The image looks blurry or pixelated
The source image is lower resolution than the space it's filling. Use a larger original, or scale the placed image down until it sharpens up. Avoid enlarging a small image past its natural size.
The image is covering text I need to see
Images render as a top layer. Drag it into a margin or empty space, or resize it smaller. If you need it behind the text instead, that isn't possible with a simple overlay — rework the layout so the image sits in clear space.
It landed on the wrong page
Images are added to whichever page is in view when you insert them. Scroll to the correct page first using the thumbnails, then place the image — or delete it and re-add it on the right page.
It looks fine on screen but prints wrong
This is usually a resolution or color issue rather than a placement one. A screen-resolution image can print soft; start from a higher-resolution source. If you want the image locked so it can't shift in another viewer before printing, consider flattening the PDF.
Adding Images on Phone, Tablet, and Desktop
- Windows / Mac (any browser): The steps above are identical — no install needed. Drag-to-position is easiest with a mouse or trackpad for fine placement.
- iPhone / iPad: Open EditPDFs.app in Safari and pick the image straight from your Photos library or the Files app. Pinch and drag to position with touch.
- Android: Use Chrome the same way — insert from your gallery or downloads, then drag the image into place and export.
A Note on Privacy
The images people add to PDFs are often personal — a scanned signature, an ID photo, a private document. Many online editors upload both the PDF and your images to their servers to process them. EditPDFs.app does the work entirely in your browser, so neither the document nor the image you insert ever leaves your device.
Frequently Asked Questions
Is it free to add images to a PDF?
Yes. On EditPDFs.app it's completely free with no signup, no watermark, and no limit on how many images or documents you work with.
Will adding an image reduce its quality?
No. The image is embedded at the resolution of the file you upload — what you put in is what you get out. Any blurriness comes from the source image being too small for the space, not from the insertion itself.
Can I add several images to one PDF?
Yes. Add as many as you like across any pages. They can also overlap — a later image sits on top of an earlier one, which is useful for layering a logo over a banner, for example.
Which format is best for a logo or signature?
A PNG with a transparent background. It places cleanly with no white box, so the logo or signature blends into whatever is behind it on the page.
Why did my PDF get so much larger after adding a photo?
High-resolution photos carry a lot of data. Resize the photo before adding it, or compress the finished PDF if you need to email it. A logo or signature adds almost nothing by comparison.
Can I move or delete the image after placing it?
Yes — until you export, the image stays a selectable object you can drag, resize, or remove. Once you've downloaded the file, it's embedded into the page.
Does this work on my phone?
Yes. EditPDFs.app runs in any mobile browser, and you can pull images straight from your photo library — handy for adding a photo of a signature or an ID to a form on the go.
