How to Remove Image Metadata (EXIF) Before Sharing
Strip hidden GPS coordinates, device info, and timestamps from your photos before they reach anyone else
Strip Metadata NowEvery digital photo carries more than what you see on screen. Hidden inside the file is a block of structured data called metadata that records where the image was taken, which device captured it, the exact date and time, and sometimes even the software you used to edit it. This information travels silently with the file every time you share, upload, or send it.
Most people never think about this hidden layer because image viewers and social feeds display only the visible pixels. Yet anyone who downloads your original file can inspect the metadata in seconds using free tools or a simple right-click. A single photo shared on a forum, marketplace, or messaging app can reveal your home address, your daily routine, and the exact phone you carry, all without you realizing it.
The good news is that removing metadata is straightforward. In this article, we explain what image metadata contains, why it matters for your privacy, and how to strip it safely from PNG, JPG, WebP, and other common formats before you share anything online.
What Is Image Metadata?
Image metadata is structured information stored inside a photo file alongside the actual pixel data. It is written automatically by cameras, phones, and editing software at the moment of capture or processing, and it persists through most file operations, including format conversions and resizing. There are several distinct types you should know about.
EXIF (Exchangeable Image File Format) is the most common and most detailed type. It records camera settings like shutter speed, aperture, ISO, and focal length. It also stores the device manufacturer and model, the date and time the photo was taken, and an orientation flag that tells software how to rotate the image for correct display. Critically, EXIF can include GPS coordinates with enough precision to identify a specific building or street address.
ICC color profiles describe how colors in the image should be interpreted and displayed. Profiles like sRGB or Adobe RGB ensure colors look consistent across different screens and printers. These are generally harmless from a privacy standpoint, but they do add to the file size.
XMP (Extensible Metadata Platform) is an Adobe-developed standard that stores creator information, copyright notices, keywords, and editing history. Professional photographers use XMP to track intellectual property, but for casual sharing it can reveal your real name and editing tools.
Comments and custom fields are free-text areas where software can write arbitrary data. Some editing applications embed the full version string, license info, or processing notes into these fields.
Not all metadata is visible in your operating system's file properties. Many fields require dedicated EXIF viewers or command-line tools to inspect, which is precisely why most people never realize how much data they are sharing. The table below summarizes the most common fields and their associated risk levels.
| Field | What It Reveals | Risk Level |
|---|---|---|
| GPS Coordinates | Exact latitude, longitude, and sometimes altitude of the capture location | High |
| Device Make/Model | Manufacturer and model of the camera or phone used | Medium |
| Serial Number | Unique identifier that can link multiple photos to one device | Medium |
| Date/Time | Precise timestamp of capture, modification, and digitization | Medium |
| Software Tags | Name and version of editing or processing applications | Low |
| ICC Color Profile | Color space information (sRGB, Adobe RGB, etc.) | Low |
| XMP Creator Info | Author name, copyright text, keywords, and descriptions | Medium |
| Thumbnail | Embedded preview that may retain data from a pre-crop version of the image | Medium |
How to Remove Metadata from Your Images
There are several approaches to stripping metadata, ranging from manual re-exporting to dedicated tools. The method you choose depends on how many images you need to process and how thorough you want the removal to be.
Re-export Through a Canvas-Based Converter
The most reliable way to remove all metadata is to pass the image through a tool that decodes the pixels and re-encodes them into a fresh file. When an image is drawn onto an HTML Canvas element and then exported, only the raw pixel data is written to the new file. All EXIF, XMP, GPS, ICC profiles, comments, and thumbnails are left behind because Canvas operates exclusively on pixel values. This is the approach pic2PNG uses: your image is decoded in the browser, drawn to Canvas, and exported as a clean PNG with zero metadata.
Use the Strip Metadata Option
pic2PNG includes a dedicated Strip Metadata toggle. When enabled, the converter explicitly removes all embedded data fields during processing. Combined with the Canvas pipeline, this gives you a double layer of assurance that nothing beyond the visible pixels makes it into the output file.
Dedicated Metadata-Stripping Software
Desktop tools like ExifTool, ImageOptim (macOS), and the Windows file properties dialog can also remove metadata. These are useful if you need to strip metadata from files without changing the format. However, they require installation and, in the case of ExifTool, familiarity with command-line syntax. A browser-based approach like pic2PNG is faster for quick tasks and requires no setup.
Re-save in an Editor
Opening an image in a photo editor and saving it as a new file often drops some metadata, but this is not guaranteed. Many editors preserve EXIF data by default. Unless the application has an explicit option to exclude metadata on export, you cannot be certain the output is clean.
What to Watch Out For
Stripping metadata is usually straightforward, but there are a few things worth keeping in mind to avoid unexpected results.
Color Profile Removal Can Shift Colors
ICC color profiles tell displays and printers how to interpret the colors in your image. If you strip the profile along with the rest of the metadata, the image may look slightly different on some screens because the viewer will fall back to assuming sRGB. For casual sharing and web use, this difference is rarely noticeable. But if color accuracy matters, for example in product photography or print work, consider keeping the original file with its profile intact for those purposes and only stripping metadata on copies destined for public sharing.
Always Keep Your Originals
Metadata stripping is a one-way operation. Once the data is removed and the file is saved, you cannot recover the GPS coordinates, timestamps, or camera settings from that copy. Always work on duplicates and keep your original files in a private archive. The original metadata is genuinely useful for organizing your personal photo library, searching by date or location, and maintaining editing history.
URL and Cloud Imports Involve a Server
When you import an image into pic2PNG via a URL or a cloud service like Google Drive or OneDrive, the file is fetched through a server-side route before it reaches your browser for processing. The actual conversion and metadata stripping still happen locally in your browser, but the import step means the file briefly passes through a server. If you are handling highly sensitive images, drag-and-drop from your local device is the most private import method because it avoids any network transfer entirely.
Bonus: Stripping Metadata Reduces File Size
Beyond privacy, removing metadata has a practical benefit: it makes your files smaller. Color profiles alone can add 3 to 5 KB to a file, and some wide-gamut profiles exceed 30 KB. EXIF blocks with embedded thumbnails, detailed camera data, and editing histories can add tens of kilobytes more. For a single image the savings may seem modest, but across a website with hundreds of images, the cumulative reduction in page weight is meaningful for load times and bandwidth.
You can amplify these savings by combining metadata stripping with other optimizations. pic2PNG offers resize and PNG optimization tools that reduce pixel dimensions and compress output files without visible quality loss. Resize an oversized 4000-pixel photo down to 1200 pixels, strip the metadata, and export as an optimized PNG, and you can often reduce the file from several megabytes to a fraction of that size.

Conclusion
Image metadata serves a useful purpose in personal archives and professional workflows, but it becomes a liability the moment you share a file publicly. GPS coordinates can reveal your home address, device identifiers can link your photos across platforms, and timestamps can map your daily routine. None of this information is visible in the image itself, which is exactly what makes it dangerous.
The simplest defense is to strip metadata before sharing. Use pic2PNG to convert your images to clean PNG files with all hidden data removed, entirely in your browser with no server uploads. Keep your originals safe in a private archive for personal use, and share only the stripped copies.
