About Us

Toolsaku is a small collection of free online tools for everyday jobs: resizing a photo for Instagram, shrinking a file to fit an email, or turning a WEBP into a JPG.

Saku (作) is Japanese for create: free tools that help you make things.

Every tool runs in your own browser. Your files are never uploaded to a server, there is no sign-up, and the tools keep working on slow connections once the page has loaded.

There are 42 tools today, across images, PDFs, video, text, social media, calculators and everyday utilities, and we add new ones regularly.

Meet the developer

Hi, I'm Aditya Kumar, the developer behind Toolsaku.

I built Toolsaku because most free tool sites are slow, full of ads, and want you to upload your files. Every tool here runs right in your browser, so your photos, PDFs and videos never leave your device.

It's a one-person project, and I add new tools regularly. Have an idea or found a bug? I'd love to hear from you.
