425 free online tools; most run in your browser
ZIPZAX provides a free suite of 425 online tools for routine digital tasks, organized into 14 categories such as Documents & PDF, Images, Development, Data and Calculators. Most tools run entirely in the browser, processing files locally via WebAssembly without uploading them. The platform also includes dedicated Studios for image, video, PDF, diagram and resume work, plus a code playground and a Python notebook, all created by a three‑person team in Lisbon, Portugal.
