The short answer
Why use Size Finder?
File properties often explain why an image prints poorly, rotates unexpectedly, or reveals more information than intended. Reading the file first prevents guesswork.
Size Finder focuses on reading the width, height, and file size of an image. The inspector reports what the file contains and says when a tag is absent. It does not invent DPI, GPS, camera, or shutter data that was never stored.
The selected file stays in this browser tab and is released when you leave the page. Metadata fields are optional and can be removed by messaging apps or editors. A missing value is different from a zero value.
What Size Finder does
Open the source file
Drop, choose, or paste a supported file into Size Finder. Reading the width, height, and file size of an image. The source stays on your device; we work on a copy.
Read what is actually there
Size Finder is for reading the width, height, and file size of an image. The preview is the place to decide if the setting went too far. The original file is not overwritten.
Useful controls
Main controls: File selection and read-only result details. Working limit: 50 MB and 50 megapixels per image. Watch the preview at full size before you save. A current desktop browser usually has more memory than a phone.
Leave with the facts
Export is on-screen dimensions, metadata, colors, or extracted previews depending on the tool. The download is a new file. Keep the original until you have opened the copy once.
Where Size Finder fits
These are ordinary jobs where the focused controls save time. They also show where a full editor or a manual review may still be the better choice.
Before publishing
Check dimensions and metadata before an image leaves your device.
Troubleshooting
