이미지 형식 변환
What this tool does
Change image file type between common web formats while keeping the picture content. Convert PNG to JPEG for smaller size, or JPEG to PNG when you need a lossless copy.
Supported formats
Input: JPEG, PNG, WebP, GIF. Output: PNG, JPEG, or WebP (one file per input). Multiple files can be converted in one batch.
How to use
Add one or more images, select the target format, click Convert, then download each result. Transparent PNG areas may become a solid background when converting to JPEG.
Limitations & tips
Converting to JPEG always loses some quality and does not preserve transparency. GIF animation is not preserved — only the first frame is used. Extremely wide or tall images may be slow on low-end devices.
