Input and processing example
Compare it yourself · Illustrative example
확인 / Check 파일: 20 MB 이하 / file up to 20 MB 픽셀: 20,000,000 이하 / pixels up to 20 million 각 변: 8192 px 이하 / each side up to 8192 px
Steps to verify
- Check format and file size.
- Check width × height and each side.
- Prepare a suitable copy in the source editor if needed.
How to interpret the result
Supported inputs are PNG, JPEG and WebP. Entering a larger resize maximum does not bypass an input limit.
Deciding what to do next
Do not disguise an unsupported file by renaming its extension. Actual format and browser decoding matter.
Feature scope
Downsize PNG, JPEG and WebP proportionally in the browser without upscaling. Inputs are bounded by 20 MB, 20 megapixels and 8192px per side; metadata and animation are not preserved as originals.
