Field notes
The page describes an in-browser workflow that tests multiple encoded versions, compares them with the original using PSNR, and keeps the smallest result above a stated 40 dB fidelity floor. A separate Target Size mode searches for a file under a specified KB budget, while batch jobs run in parallel and can return a ZIP archive. The visible examples include HEIC, PNG, and JPG inputs, including one JPG reduced to a 200 KB target.
