- Select Process, review the result, and download it.
The method, explained
The browser decodes the image and reports its pixel dimensions; file size is measured in bytes.
A 1920 × 1080 image contains 2,073,600 pixels and has a 16:9 aspect ratio.
What to keep in mind
JPG, PNG and WebP inputs only, up to 20 MB total and 24 million decoded pixels per image. Animated files are treated as still images. JPEG uses a white background for transparency. Output size may increase; review the preview and size.
Common questions
Are my files uploaded?
No. This tool processes files in your browser. Files are not sent to ClarityKit or an external API. Reset the tool or close the tab to release the working files.
What should I do if processing fails?
Check the supported formats and limits above. Try a smaller, unencrypted file and keep the tab open until the result is ready.
