Frequently Asked Questions

Why did the background turn white (or black) after PNG → JPEG?
JPEG has no alpha channel, so transparent pixels must be filled with a concrete color — the tool defaults to white with other options available. To keep transparency, convert to WebP, which supports alpha alongside lossy compression.
Do repeated conversions degrade quality?
Every lossy transcode (JPEG/WebP) accumulates loss. Keep a lossless master (PNG/TIFF) and derive all versions from it — avoid the JPEG-of-a-JPEG generational smear.
Can it convert HEIC (iPhone photos)?
It depends on the browser’s decoder: Safari supports HEIC natively; Chromium-based browsers often do not. If conversion fails, export JPEG from the system first, or set the iPhone camera to "Most Compatible" before shooting.
