About Wei2 Tools

Wei2 Tools brings image processing, unit and time conversion, and developer utilities into one browser-based toolbox.

Tools with explanations

Resize and watermark images, inspect JSON and regular expressions, or convert units and timestamps. Each tool explains its inputs and limits. Practical guides show concrete settings, expected results, and common mistakes.

Local processing and privacy

Tool inputs are processed on your device without an account. Images and entered text are not uploaded by the processing tools. Downloads create separate files. Web analytics and feedback forms have their own data handling, described on the privacy page.

Understand the limits

These are preparation tools, not a professional prepress service. The first version accepts static JPG, PNG, and WebP images. It does not provide RAW or HEIC decoding, CMYK separations, ICC proofing, AI detail recovery, or guarantees about a printer’s output. Browser rendering may change color profiles and removes most original metadata from exported copies.

Check your print provider’s instructions and keep original files. If the image matters, make a test print before ordering a large run.
