Most processing is designed to run in the browser whenever possible, which makes the tool useful for quick personal or work files. For sensitive, production, or regulated material, test with a sample first and confirm the target platform's format, size, and quality requirements.
Common questions
Will format conversion preserve transparent backgrounds?
Not always. JPEG does not support transparency, so use PNG or WebP when alpha transparency matters.
Is WebP better than JPEG for websites?
WebP often produces smaller files at similar quality, but you should still consider browser and platform compatibility.
What should I check before batch converting images?
Confirm target format, transparency, quality settings, and output filenames so original assets are not accidentally overwritten.
