FAQ
Frequently Asked Questions
Is it safe to use this Image Size Finder with my photos?
Yes, completely safe. This tool runs 100% in your browser using JavaScript. Your images are never uploaded to any server. No data leaves your device, making it ideal for sensitive or private images.
What image formats does this tool support?
The Image Size Finder supports all major formats including JPEG, PNG, WebP, GIF, BMP, SVG, TIFF, HEIC, AVIF, ICO and more. Any format your browser can read will be analyzed instantly.
Can I check multiple images at once?
Yes! You can upload multiple images at once by selecting them all at once via the file picker, or dragging a batch of images into the drop zone. Each image gets its own detailed analysis card.
How does the DPI unit converter work?
Select a DPI preset (72, 96, 200, 300) or enter a custom value. The tool converts your image's pixel dimensions into inches, centimeters, and millimeters at that resolution. For print, 300 DPI is recommended.
Is there a file size limit for the images I can check?
No file size limit. Since processing happens entirely in your browser, you can check images of any size. However, very large files may take a moment to load depending on your device's speed.
What is megapixel count and why does it matter?
Megapixels = (Width × Height) / 1,000,000. It tells you the total pixel count of an image. Higher megapixels mean more detail, which is important for large prints and professional photography. A 12MP image (e.g., 4000×3000) prints clearly at large sizes.
Can I paste an image directly into the tool?
Yes! Simply copy an image (e.g., from a webpage or screenshot) and press Ctrl+V (Windows) or Cmd+V (Mac) anywhere on this page. The tool will instantly analyze the pasted image.
What Is an Image Size Finder?
An image size finder is an online tool that reads metadata from image files to display their width and height in pixels, file size in KB or MB, aspect ratio, megapixel count, and other technical properties. Unlike traditional desktop tools, our browser-based solution processes everything locally - your images are never sent to a server.
Why Check Image Dimensions Online?
Knowing your photo dimensions is essential for web design, social media posting, print preparation, and photo editing. For example, Instagram requires specific image sizes, web performance depends on image file size, and print quality is determined by pixel dimensions relative to DPI.
Image Size vs. File Size - What's the Difference?
Image dimensions refer to the width and height in pixels (e.g., 1920×1080). File size refers to how many kilobytes or megabytes the image occupies on disk. A large 5000×4000 pixel image can have a small file size if compressed well (WEBP, JPEG), or a large file size if saved as RAW or TIFF.
DPI and Print Size Calculator
DPI (Dots Per Inch) determines how large your image prints at a given quality. At 300 DPI (print quality), a 3000×2400 pixel image prints at 10×8 inches. At 72 DPI (screen), the same image appears much larger. Use our built-in unit converter to find the exact print size of your image.
Supported Image Formats
Our image size checker supports JPEG, PNG, WebP, GIF, BMP, TIFF, SVG, HEIC, AVIF, ICO and virtually any other format your browser can handle - including modern formats used by the latest smartphones and cameras.
