TL;DR: PDF files often carry hidden metadata—camera EXIF data, GPS locations, and software fingerprints—that can expose your identity when you share documents. The fastest way to remove this metadata is to create a fresh PDF from your images using a browser-based tool that processes files locally, such as OctopusPDF’s Images to PDF converter, which strips source metadata automatically without uploading your file [K1][K3]. This guide walks you through the process in four steps.
What You Will Need
- A web browser (Chrome, Firefox, Safari, or Edge—any modern version works)
- The image files you want to convert (JPG, PNG, scans, or screenshots)
- An internet connection to load the tool (after that, processing happens locally)
- Optional: a PDF file whose metadata you want to inspect (for verification)
No account, software installation, or payment is required for the core workflow described below.
| Item | Requirement | Notes |
|---|---|---|
| Browser | Any modern browser | The tool runs entirely in your browser tab |
| Source files | JPG, PNG, scans, screenshots | One image becomes one PDF page [K4] |
| Upload | None | Files never leave your device [K1][K4] |
| Metadata handling | Automatic | EXIF, location, software fingerprints are stripped [K3] |
Step-by-Step Instructions
Step 1. Open the Images to PDF Tool in Your Browser
Navigate to https://octopuspdf.com/images-to-pdf in your browser.
This tool works entirely in your browser tab. Your images never upload to a server, so there is no intermediate server that could log, store, or leak your data [K1][K4]. This is the core difference between this approach and upload-based redaction tools, which create a privacy paradox by sending your file through a third-party server to "protect" it [K2].
Watch out: Do not use this step with sensitive images if your employer or network blocks local browser features like JavaScript or WebAssembly. If the page fails to load interactively, try a different browser before proceeding.

Step 2. Add Your Images to the Conversion Queue
Drag and drop your images into the designated drop zone, or click the file picker button to select images from your device.
The tool supports multiple images. You can reorder them after adding, because the order you arrange determines the page order in the final PDF [K1]. Each image becomes one page in the output PDF [K4].
Watch out: If you are converting images that contain location data (for example, photos taken on a smartphone), do not rely on your operating system's file browser to tell you whether location data exists—many OS viewers do not display this. Trust the tool to strip it, and verify with Step 4.

Step 3. Convert the Images to a Clean PDF
Click the conversion button (typically labeled "Convert" or "Create PDF").
The conversion happens locally in your browser. The output PDF will contain no metadata from the source images—no camera EXIF data, no GPS location, no software fingerprints [K3]. Because the whole process runs in your browser, there is nothing to leak: the images never upload, and the resulting PDF is generated without carrying over hidden data [K4].
| Metadata Type | Status in Output PDF | Source |
|---|---|---|
| Camera EXIF (make, model, lens) | Removed | [K3] |
| GPS location | Removed | [K3] |
| Software fingerprints (editor IDs) | Removed | [K3] |
| Source image metadata | Removed | [K1] |
Watch out: If you add a large number of images (for example, more than 50 high-resolution photos), the local processing may take a minute. Do not close the browser tab during conversion. If your device has low memory, close other tabs to free resources.

Step 4. Download and Verify the Output PDF
Click "Download" to save the resulting PDF to your device.
After downloading, you should verify that the metadata was indeed stripped. The most reliable way is to check the document properties in your PDF viewer:
- Open the downloaded PDF in your viewer (Adobe Acrobat, Preview on macOS, or a browser).
- Navigate to File → Properties (Acrobat) or Tools → Show Inspector → Document (Preview on macOS).
- Inspect the "Description" and "Advanced" tabs for any metadata fields.
Alternatively, use a text editor to open the PDF and search for string patterns like EXIF, GPS, or your camera model name. If these appear, metadata remains; if not, the clean-out succeeded.
Watch out: Some PDF viewers, especially web browsers, automatically modify or add metadata when saving a copy. For verification, use a dedicated desktop PDF application rather than a browser's PDF viewer.

Common Mistakes / Troubleshooting
| Problem | Likely Cause | Fix |
|---|---|---|
| The tool does not process my images | Browser JavaScript is disabled or blocked by an extension | Enable JavaScript, disable privacy extensions temporarily, or try a different browser |
| The output PDF still shows location information | You are viewing the original image file, not the PDF | Verify the downloaded PDF file, not the source image; check file properties of the PDF itself |
| Images are in the wrong page order | You added them in the wrong sequence | Reorder the images in the queue before converting [K1] |
| Conversion is very slow with many images | Local processing requires device memory | Close other browser tabs, reduce image count, or batch convert |
| Worried about privacy despite the local processing | You may be using a browser with sync or cloud features that store local activity | Use a private/incognito window, or use a clean browser profile |
How to Verify Success
- The PDF downloaded from OctopusPDF opens correctly.
- In the PDF properties, the "Author" field is empty or absent.
- Search the PDF file for
EXIForGPS—no matches found. - The PDF does not contain your camera model name or device name.
- No file was uploaded: check your browser's network tab (F12 → Network) during conversion—no requests to external servers for the image data [K1].
If all checks pass, your output PDF is clean and ready to share.
FAQ
Q1. Does OctopusPDF upload my images to a server?
No. The Images to PDF tool processes your files entirely in your browser. Per the official documentation, "Your file never uploads—processed in your browser" [K1]. This is the key difference from upload-based redaction tools, where your file passes through a third-party server [K2].
Q2. Will this tool remove metadata from an existing PDF?
No. This workflow converts image files into a new PDF, stripping source metadata in the process. If you already have a PDF with embedded metadata, you would need a different tool—OctopusPDF offers a redaction and sanitization service that also runs entirely in the browser [K2].
Q3. What about AI features like Summarize or Translate—do they upload my PDF?
No. OctopusPDF's AI features (Summarize and Translate) parse your PDF inside the browser tab using pdf.js. Your API key stays in browser localStorage, and the browser connects directly to the OpenAI-compatible endpoint you entered. OctopusPDF does not proxy the request, so there is no server-in-the-middle [K5].
