Every creator's tiny toolkit — private, free, instant.
ZipCraft is a collection of micro-tools that run entirely in your browser. Resize, crop, convert and fix images for any platform — YouTube, Instagram, TikTok, Discord and more — without your photos ever leaving your device.
Small tools. Big time-savers.
We build tiny, focused tools that solve one problem really well — with accurate specs, no bloat and no privacy trade-offs. New tools ship regularly.

One goal: no empty tool tab should win.
Creators lose hours fighting between mismatched platform ratios — a thumbnail crops wrong, a story gets letterboxed, a post looks stretched. We researched what people actually struggle with, then built tools that give the exact correct answer in seconds: the precise ratio, the exact resolution, and every major platform's requirements on the same page.
ZipCraft is a micro-SaaS in the truest sense — small, sharp, and free. As we grow, every tool stays free and private, and every tool user is treated like the reason we exist.
