Using Toolkatsu
Toolkatsu provides free browser-based image utilities. Use images you own or have permission to process. Do not use the service to violate another person’s rights, distribute illegal material or interfere with the website.
Check the result
Compression can change image quality and dimensions. JPG removes transparency and uses a white background. Re-encoding may remove metadata and change color rendering. Keep an original copy and inspect the downloaded result before submitting or publishing it. A receiving website may impose requirements this tool cannot check.
Availability and responsibility
Browser support, memory and file characteristics can affect processing. We do not guarantee uninterrupted service, recovery of unsaved work or suitability for every submission requirement. Nothing here excludes responsibility or consumer rights that cannot legally be excluded.
Ownership and changes
You retain your rights to your images. Toolkatsu does not acquire ownership by processing them. Features and these terms may change; the effective date will be updated when the terms change. Questions: [email protected].
