SMALL PRINT, PLAIN WORDS

A few words about Tsubami

Everyday file jobs should feel small.

Tsubami is a collection of focused image and PDF tools. The goal is simple: help you finish a practical task without an account, subscription or unnecessary steps.

A smaller, clearer toolkit

We focus on image compression, resizing and conversion, plus creating and organizing PDF pages. We show limits before you choose files and explain what each tool can change. We explain each conversion’s limits before you begin. There is no AI or OCR; editing adds new elements and some exports simplify the original layout.

Your device does the work

File contents are processed in your browser instead of being sent to a processing server. Your device’s memory and browser capabilities determine how large a job it can handle. Keep your originals and inspect the output.

How this stays free

The tools are free. We plan to support the site with clearly labelled advertising. Advertising, if enabled, is kept separate from processing and download controls. The basic tools do not require watching an ad.
