Can I process multiple files at once?
Yes. Upload as many files as you need. They process sequentially and you can download them individually or all at once as a ZIP file.
Why is the converted PNG larger than my HEIC?
HEIC uses lossy compression (like JPEG) while PNG is lossless. The quality is preserved perfectly, but lossless formats produce larger files. Try WEBP for a good balance of quality and size.
