FAQ

• Can I inspect transparency?：Yes. The preview area shows PNG transparency and image content directly in the browser.
• Why are PNG files often larger than JPG?：PNG favors lossless storage and is commonly used for transparency and high-fidelity UI assets.

Privacy

Image preview, thumbnail generation, and decoding run locally in the browser and do not upload your files to the server.
