FAQ
Where does image dpi metadata viewer process my image?
Processing runs in this browser tab. The selected file is not intentionally uploaded by this page.
What happens with very large images?
Images above the stated pixel or frame limits are stopped before processing to reduce the risk of a frozen tab.
Does this tool change the original file?
No. The original file remains untouched; the download is a newly created output or report.
Which browsers can run this image tool?
Current desktop and mobile browsers with Canvas, Blob, and modern JavaScript support work best. Format decoding still varies by browser.
Why might the result differ from desktop software?
Browser decoders, encoders, color management, and metadata support can differ from dedicated desktop applications.
