To provide better customization services, vendors typically require you to supply a customization file. Here are some common formats for files:
1. Before the payment:
You are interested in product customization and want to get a preliminary customization pricing stage.
- JPEG/JPG:
-Commonly used for photographs and complex images, offering a smaller file size through compression, but lacking support for transparent backgrounds.
- PNG:
-Supports transparency, making it suitable for images that require a clear background, such as logos and icons
Reason: The reason the supplier requires image format customization files at the preliminary confirmation stage is to understand your customization needs and provide you with an initial quote based on them.
2. After the payment:
You have decided to proceed with product customization, and the supplier’s required file formats for customization.
- AI (Adobe Illustrator):
-Ideal for professional design work, supporting high-quality vector graphics that can be easily scaled without losing quality.
- PDF (Portable Document Format):
-Versatile for sharing and printing, capable of containing both vector and bitmap graphics, ensuring design consistency across different platforms.


Reason: The reason the supplier requires AI or PDF format customization files in the formal customization stage is that these formats are clearer than image formats, allowing the supplier to achieve the best results when customizing the product.
In general, during the initial stages of customization confirmation, vendors will only require a logo in an image format.
After you make the payment and before the customization process begins, they will need you to provide the logo in PDF format.
