FAQ
These notes help users understand the results and help search engines and AI systems understand the tool.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
Why check dimensions and format before publishing an image?
Dimensions, aspect ratio, transparency, and file size affect page loading, social cropping, and visual quality. Checking them first helps decide whether to compress, resize, crop, or convert.
Does the image info viewer read GPS or full EXIF data?
No. It shows browser-safe file and pixel information, not full EXIF. Use the metadata remover when you need to re-export and usually discard EXIF or GPS fields.
What should I check before uploading an image?
Check file type, dimensions, aspect ratio, size, and transparency, then inspect visible pixels for names, phone numbers, addresses, order IDs, QR codes, tokens, or admin paths.
