常见问题

Are my TIFF images uploaded?

所有处理都在浏览器本地完成,无需上传文件。

Can I convert TIFF to ICO online?

Yes. This page opens the converter with ICO selected as the output format.

Will the file size change after conversion?

ICO output can be smaller or larger depending on compression, transparency, colors, and image dimensions.

Can I control output quality?

Quality control is available for JPG, JPEG, and WebP output. PNG, BMP, TIFF, GIF, and ICO have different export behavior.

Does conversion keep transparency?

PNG and WebP can preserve transparency. JPEG/JPG output uses a background because JPEG does not support alpha transparency.

Why can very large images fail?

Browsers limit memory and canvas size. Try smaller dimensions or fewer files if conversion fails.
