Why use this tool?

Use this free browser utility when you need a focused result without installing desktop software or creating an account. The workspace is designed for a single task, with the input, controls and output kept together.

Privacy, compatibility and limitations

File sizes vary widely with compression, resolution and format. Drives have filesystem overhead; available capacity differs from marketing capacity and operating systems may use binary units.

Before you download: Check the output visually or technically before replacing an original file. Browser support, device memory and source-file structure can affect results.

Questions about Storage Capacity Calculator

How many photos fit on 64 GB?

It depends on average file size: at about 4 MB each, the theoretical count is roughly 16,000 before overhead.

Does a 1 TB SSD have 1 TiB usable?

No. Manufacturers generally use decimal units and filesystem formatting reduces usable space.
