I built ResizeKit, Batch Image Resizing & Renaming for E-commerce & Social Media

One upload. Multiple platforms. Perfectly sized and organized product images.

Preparing product images for different e-commerce platforms can be surprisingly tedious. Each platform has its own image size requirements, and manually resizing, renaming, and organizing dozens of images takes time.

I built ResizeKit with Base44 to make that process simple.

ResizeKit is a micro-SaaS that helps e-commerce sellers, store owners, and creators batch resize and rename product images in just a few clicks.

How it works

Upload your images: Drop in multiple product images, even if they have messy or inconsistent filenames.

Choose platform presets: Select one or multiple presets, such as Shopify, Amazon, or Etsy.

Customize your output: Enter a product name and choose how images fit: Contain, Cover, or Stretch.

Process and download: ResizeKit processes the images and packages everything into a single ZIP file.

Each platform gets its own folder, with automatically generated, consistent filenames. For example: female-jacket-shopify-2048x2048.png

Why I built it A simple task like preparing product images shouldn't require opening an image editor, manually adjusting dimensions, and renaming every file.

ResizeKit turns that repetitive workflow into a quick, organized process, helping sellers spend less time preparing assets and more time running their businesses.

Built with Base44. Designed to make everyday e-commerce workflows a little easier.
