PNG preserves alpha. Browser colour conversion can change appearance; the original colour profile is not copied. Files and settings are cleared when you leave.

Before you export
Text uses the system sans-serif font available in your browser. Logo transparency and chosen opacity combine in the output. A watermark that does not fit blocks export.
Images are decoded and exported one at a time. The output archive is limited to 64 MiB. Original files are preserved, and watermarking cannot guarantee ownership protection.
Your inputs stay in this browser. These tools work without an account. The content editor opens separately; your files are not transferred automatically.
