Direct answer: Enlarge low-resolution supplier and archive product photos in bulk — AI upscaling up to 4x with detail reconstruction, so images meet marketplace minimums without reshooting.
Starting 2026-08-07, PicTools offers a batch AI image upscaling tool for marketplace sellers and catalog teams. Upload undersized product images, choose an enlargement factor (2x or 4x), and process the entire batch at once. The AI reconstructs edge detail, textures, and printed text instead of simple interpolation, so upscaled photos stay sharp rather than blurry or painterly. Typical use cases include rescuing supplier photos that fall below marketplace minimum resolution (e.g. the 1000px long edge commonly required for zoom-enabled listings), upgrading legacy catalog images for a store redesign, or making old social media assets usable again. A before/after preview is available per image before you export the full batch as JPEG, PNG, or WebP. Available now for all registered users. Questions or feedback: sapsap@qq.com.
