File Size & Storage Converter

Turn bytes into gigabytes instantly — the exact file size and storage converter for photos, downloads, drives, and dev work.

Type a number, pick a unit, get the precise answer. No ads, no rounding tricks, no confusing charts — just an exact converter with a clean, fast interface.

KEY FEATURES

• Convert bit, byte, KB, MB, GB, TB and PB both ways, live as you type

• Switch decimal (1000-based) and binary (1024-based) units in one tap

• Transfer-time estimator — see exactly how long a download or upload takes on 3G, 4G, 5G, Wi‑Fi, or fiber

• Storage planner — see how many photos, songs, or hours of video fit on any drive or phone

• Pin favorite conversions and keep a saved history

• Plain-language reference on why a "1 TB" drive shows less, and other storage facts

HOW IT WORKS

1. Enter a value and choose the units you're converting between

2. Read the exact result instantly, no calculator needed

3. Save it for later, or switch to Transfer and Planner for real-world estimates

Full access to the transfer-time estimator, storage planner, and complete all-units view is part of File Size Premium, available as a weekly, yearly, or lifetime option. The core converter works without any purchase.

File Size runs entirely on your device — no account, no ads, and nothing you type ever leaves your phone.
