Format & Upload 259 T-Shirts

I have 256 finished T-shirt graphics sitting in HEIF/HEVC format. I need each one converted to a Printful-ready file and then added to my Printful store.

Here’s what I’m expecting:
• Convert every HEIF/HEVC design to the correct file type and resolution that Printful accepts by default.
May require first converting to Vector before formatting to PNG but also may not.
- Maintain correct image size, correct file format, and appropriate DPI resolution for highest quality final product.
Ensure designs have correct print size for full chest print across various adult and children's shirt sizes
- Ensure accurate color profile and bleed area in prepared files.
• Keep the original artwork intact—no creative changes, just precise formatting and placement.
Ensure consistent sizing, placement, and file quality across designs.
• Upload each design to my Printful account
Conduct a successful test run of final product to ensure quality standards.

I’ll give you access to the raw files and to my Printful dashboard. Once the last design is sitting safely in Printful, send me a quick confirmation and links so I can hit “publish.”

If you have experience batch-processing files in Photoshop, Affinity, or similar and know your way around the Printful interface, this should be straightforward. Turnaround time is flexible, but let me know how fast you can realistically handle all 256 designs. I would like the project completed by the end of October for lunch in November.
