The AI Sign Designer now accepts PDF uploads, making it even easier for your customers to turn artwork they already have into a custom sign. PDFs are one of the most common formats designers and businesses use for logos and brand artwork, so this removes a frustrating extra step for customers who previously had to convert their files before uploading.

When a customer uploads a PDF, the AI Sign Designer processes it automatically, just like a photo or image, producing a sign-ready preview and the production files you need to fulfil the order.

## What’s Changed

- **PDF uploads now supported**Alongside JPG, PNG, SVG and photos, customers can now upload PDF artwork directly into the AI Sign Designer
- **Automatic conversion**Uploaded PDFs are turned into a sign-ready design with no extra effort from your customer
- **Larger files welcome**PDF artwork can be up to 25MB, comfortably covering the high-resolution files designers typically supply
- **Clear feedback on problem files**Unreadable or password-protected PDFs are handled gracefully, so customers get a helpful message instead of a broken upload
