Metadata Inspector Guide
Reference for using Metadata Inspector with supported inputs, browser limits, common mistakes, and related AscendLab image tools.
Quick answer
Use the Image Metadata Inspector when you need quick image facts before choosing another tool. It helps decide whether to resize, compress, convert, strip metadata, or create a favicon.
What this tool does
Inspect image dimensions, type, transparency, animation hints, EXIF presence, and browser readability before editing or publishing.
Supported input
- Browser-readable image files
- Dimension checks
- Basic metadata and transparency checks
Not a fit for
- RAW camera formats
- Complete color-profile inspection
- Server-side validation
Data handling and processing behavior
Processing is handled in the browser for this tool based on the current public implementation. Avoid using sensitive images unless you have reviewed the implementation and your own data handling requirements.
Step-by-step use
- Open Metadata Inspector.
- Choose a browser-readable local image or provide the required source input.
- Review the supported formats, file size guidance, and output settings.
- Generate the output or metadata summary.
- Download the result or copy the summary into the next workflow.
Practical examples
Logo QA. Check whether a PNG has transparent pixels before converting to JPG.
Upload planning. See whether an image is large enough to resize before compression.
Limit. This does not replace a dedicated prepress or color-management workflow.
Common errors
Converting transparency to JPG. If transparency is present, use PNG or WebP unless a matte background is acceptable.
Compressing before resizing. Large pixel dimensions often matter more than quality settings.
Ignoring browser support. Some formats can be listed but not decoded by the current browser.
Limits
- 25MB recommended limit.
- Browser memory and image decoder support can affect large files.
- Canvas-based outputs can change metadata, color profile behavior, and compression.
- Keep the source image when exact fidelity, audit trails, or metadata preservation matter.
