As answered by people managing Bootstrap and SplitImage.io.
SplitImage.io's answer:
We have not publicly named or ranked individual customers.
SplitImage.io's answer:
SplitImage.io combines a general image splitter with tools for Instagram profile grids, seamless carousels, and TikTok profile banners. Users can preview the layout, adjust the crop, and export numbered images. Image processing happens locally in the browser, and the processing engine is available as a separate open-source project.
SplitImage.io's answer:
Choose SplitImage.io when you need to turn one image into aligned, ready-to-post pieces without measuring and cropping each tile manually. You can check the result before downloading, use layouts designed for social profiles and carousels, and get the images in a numbered ZIP. Your source image stays on your device during processing.
SplitImage.io's answer:
SplitImage.io is primarily for content creators, social media managers, designers, and small businesses preparing Instagram grids, carousels, or TikTok profile banners. It also helps anyone who needs to divide an image into evenly sized pieces for print, crafts, or digital assets.
SplitImage.io's answer:
SplitImage.io started with a practical goal: make it easier to turn one image into several aligned files without manually cropping and naming every piece. The project expanded from general image splitting to workflows for social media grids, carousels, and banners. Its image-processing core was later released separately as the open-source SplitImage Engine.
SplitImage.io's answer:
The frontend uses HTML, CSS, and vanilla JavaScript with ES modules. Image processing uses browser Canvas, File, and Blob APIs, including the open-source SplitImage Engine. Cloudflare Workers serves the site and handles supporting endpoints; images are split and packaged in the browser.
