Frequently Asked Questions

LINE automatically compresses images on upload. Use high-resolution images at or above the recommended size and set JPEG quality to high to minimize quality loss.

Can I resize images for LINE for free?

Yes, ShareMint lets you resize to all LINE sizes for free. Everything runs in your browser — your images are never sent to a server.

JPEG is the most common and widely compatible format. Use PNG if you need transparency. WebP offers smaller file sizes with good quality but may not be supported everywhere.
