Frequently asked questions
What details can I see?
Resolution in pixels and megapixels, file size, format, aspect ratio, DPI, whether the image has transparency, colour profile and EXIF orientation.
How is transparency detected?
The image is drawn to a canvas and its alpha channel is sampled — if any pixel is not fully opaque, the image is reported as transparent.
Why does DPI sometimes say ‘default’?
Many web images don’t store a DPI value. When none is present we show 72 DPI, the conventional screen default. Print files usually embed a real value (e.g. 300 DPI).
Is my image uploaded?
No — everything is read locally in your browser.
