A few straightforward terms.

Effective October 28, 2026. These terms apply to the free tools and guides at tools.lingjie.cyou.

Use your own judgment

Tools and guides are provided as available. We aim for useful, accurate behavior but cannot guarantee uninterrupted access, perfect output, or suitability for every purpose. Check downloaded images, calculated results, and generated links before relying on or publishing them. Reading-time estimates are approximate. A color contrast result is not a full accessibility audit.

Your content

You retain your rights to your own input and output. Make sure you have permission to use the images and text you process. Do not use the site to infringe others’ rights, publish unlawful material, or interfere with the service. We do not claim ownership of your work.

Browser limitations

Image codecs, fonts, memory, color management, and text segmentation can vary between browsers. Image tools flatten supported images to a new raster export and may remove metadata or animation. Keep original files. Very large files may exceed the available memory on your device.

Availability and costs

The current toolkit is free and does not request payment information. Features and limits may change. Any future paid offering would require separate information and a deliberate purchase; using these tools does not start a subscription.
