EVOA Toolbox について

EVOA Toolbox is a collection of everyday tools for PDFs, images, documents, developer data, design assets and small utilities. They run in your browser, so there is nothing to install and our tools do not upload your files.

Most online converters send your file to a server. That is slow for large files and unnecessary for most tasks. Modern browsers can merge PDFs, re-encode images, parse CSV and compute hashes themselves, so that is what we use.

Local processing has trade-offs: very large files are limited by your device’s memory, and some formats depend on what your browser supports. Each tool page explains its limits.

Every tool is free to use, without sign-up. The tools process your files in your browser and do not upload them.
