- What EXIF fields does this tool compare?
- The tool shows 16 columns: file name, file size, width, height, aspect ratio, format (JPG/PNG/WebP/etc.), DPI, color space, date taken, camera make, camera model, ISO, aperture, shutter speed, focal length, and GPS presence.
- How many images can I compare at once?
- There is no hard limit. Load as many images as you need — each is processed in parallel in your browser so the table fills in quickly even for large batches.
- Why do most fields show "—" for my images?
- EXIF data is only written by cameras and some editing apps. AI-generated images (ChatGPT, Midjourney, etc.), screenshots, and images that have had metadata stripped will show "—" for camera fields. File size, dimensions, aspect ratio, and format are always shown regardless.
- Are my images uploaded to a server?
- No. Everything runs in your browser. No image data ever leaves your device, making this tool safe for private, confidential, or legally sensitive photos.
- What does the amber highlight mean?
- Any column where at least two images have different values is highlighted in amber across all rows. This makes it instantly obvious which properties differ without manually scanning the table.
- Can I export the comparison results?
- Yes — click "Export CSV" to download a spreadsheet with all 16 columns for every loaded image. The file opens in Excel, Google Sheets, or any spreadsheet app.
- Which image formats are supported?
- JPG, PNG, WebP, GIF, BMP, TIFF, HEIC/HEIF (iPhone photos), and AVIF. EXIF reading works for all formats; browser preview support for HEIC varies by OS.
