Converting images one by one is a tedious, soul-crushing task. When you have dozens or even hundreds of files, the repetitive cycle of uploading, converting, and downloading is a massive waste of time. This is where batch image conversion becomes a game-changer, allowing you to process entire folders of images in a single, efficient operation.
As the developer behind FastConverter.app, I built these tools to solve my own frustration with bulk image conversion. I wanted a solution that was fast, private, and didn’t require installing anything or trusting a third-party server with my files. That’s why FastConverter processes everything right in your browser—no uploads, no risk.
This guide explains how to batch convert your images securely and instantly, streamlining your workflow and ensuring every file is handled consistently.
Batch processing is essential in many common scenarios:
Using a browser-based tool is the fastest and most secure way to convert your images. Our tools process files directly on your device, meaning your files are never uploaded to a server. Here’s how to do it:
