📦 File Size Converter
Convert between bytes, KB, MB, GB, and TB using binary units (1 KB = 1024 B) — size up APKs, app data, downloads, and storage on your Android device, with a human-readable result.

What is a File Size Converter?
A file size converter translates a size from one unit to another — bytes to megabytes, gigabytes to megabytes, and so on. It uses binary units where each step is a factor of 1024, exactly how Android and desktop operating systems measure files, apps, RAM, and storage.
Use it to check whether an APK will fit in your remaining space, to compare download sizes, or to make sense of the raw byte counts that developer tools and log output sometimes show. Alongside the precise conversion, it gives a tidy human-readable size like "1.5 MB" so the number is easy to picture.
❓ Frequently Asked Questions
Does this converter use 1024 or 1000 bytes per KB?
1024. It uses binary units (1 KB = 1024 B, 1 MB = 1024 KB, and so on), which is how Android and most operating systems report app sizes, storage, and RAM. Storage-drive marketing sometimes uses 1000-based decimal units, which is why a '128 GB' phone shows less usable space.
Why does my Android storage show less space than advertised?
Two reasons. First, manufacturers often advertise capacity in decimal GB (1000-based) while the system reports binary GB (1024-based), so the number looks smaller. Second, the operating system, pre-installed apps, and system partitions consume part of the total before you store anything.
How big is a typical Android app?
It varies widely. A simple utility might be a few megabytes, while a game with high-resolution assets can run to several gigabytes once its data files download. Use this converter to compare an APK's listed size against your free storage before installing.
What is the human-readable result?
Alongside the exact conversion, the tool picks the largest unit that keeps the number readable — so 1,572,864 bytes is shown as '1.5 MB'. It's the same logic file managers use so sizes are easy to grasp at a glance.
