File Size Converter - Professional Tool for Developers and IT Professionals
Our free online file size converter is an essential tool for programmers, system administrators, web designers, and anyone working with digital data. The converter supports accurate conversion between all modern data storage units: from bytes to exabytes, including both decimal (SI) and binary (IEC) standards with professional-grade precision.
💾 Understanding Data Storage Units: Standards and History
Decimal system (SI standard): Uses multipliers of 1000. Kilobyte (KB) = 1000 bytes, megabyte (MB) = 1000² bytes, gigabyte (GB) = 1000³ bytes. This system is used by storage manufacturers, network equipment, and marketing materials. A 1 TB hard drive contains exactly 1,000,000,000,000 bytes under this standard.
Binary system (IEC standard): Uses multipliers of 1024 (2¹⁰). Kibibyte (KiB) = 1024 bytes, mebibyte (MiB) = 1024² bytes, gibibyte (GiB) = 1024³ bytes. Operating systems Windows, Linux, macOS display file sizes in binary units. This is why a 1 TB drive shows as 931 GiB in the system.
Historical context: Before 1998, there was confusion in using terms KB, MB, GB. The International Electrotechnical Commission (IEC) introduced standard IEC 60027-2, separating decimal and binary prefixes. This resolved decades of ambiguity in data volume measurements and established clear naming conventions.
Why the difference matters: Understanding both systems is crucial for accurate capacity planning, performance calculations, and avoiding confusion when working with storage devices, network bandwidth, and memory specifications in professional environments.
🔧 Practical Applications in Web Development
Page load optimization: Average web page should load within 3 seconds. At 3G speed (1.6 Mbps = 200 KB/s), this means maximum 600 KB per page. For 4G (25 Mbps = 3.125 MB/s), the limit increases to 9.375 MB, but Google recommends staying under 1-2 MB for optimal user experience.
Image optimization for web: Icons should be under 5 KB, logos under 20 KB, hero images under 150 KB, background images under 300 KB. WebP format reduces size by 25-35% compared to JPEG without quality loss. AVIF format provides up to 50% savings but has limited browser support.
CDN and caching strategies: Static resources (CSS, JS, images) are distributed via CDN. Recommended sizes: CSS files under 50 KB, JavaScript bundles under 200 KB. Code splitting allows loading only necessary code, reducing initial page size by 60-80%.
Modern web technologies: HTTP/2 multiplexing reduces the penalty of multiple small files. Brotli compression provides 20% better compression than gzip. Service Workers enable efficient caching strategies, reducing repeated downloads.
🗄️ Enterprise Storage Planning and Management
Corporate data growth: Enterprise databases grow 20-40% annually, logs consume 5-15% of primary data volume, backups require 2-3x space of primary data. For high-load systems, plan RAID arrays considering redundancy overhead (RAID-1: 50%, RAID-5: 20-25%, RAID-6: 33%).
Cloud storage economics: Providers use different billing systems. AWS S3 charges per GB-months, Google Cloud Storage per GB-seconds. When choosing tiers, consider access frequency: Standard (frequent access), Nearline (monthly), Coldline (quarterly), Archive (yearly access patterns).
Mobile application constraints: iOS apps are limited to 4 GB on iPhone/iPad. Android APK cannot exceed 100 MB in Google Play, additional files up to 2 GB via OBB. Games use streaming resources to reduce initial download size and improve user acquisition.
Database optimization: Indexes speed up queries but consume 20-50% of table size. Table partitioning improves performance for large datasets. Normalization reduces data duplication, denormalization improves read performance in specific use cases.
📊 Media Formats and Compression Analysis
Video codecs and quality: H.264 remains the compatibility standard, H.265 (HEVC) reduces size by 25-50%, AV1 by 30-50% compared to H.264. 4K video (3840×2160) in H.264 uses 15-25 GB/hour, in H.265 8-15 GB/hour. VP9 (YouTube) provides good quality at limited bandwidth.
Audio format efficiency: Lossless formats (FLAC, ALAC) use 700-1400 Kbps (25-50 MB per album), lossy formats (MP3 320 kbps, AAC 256 kbps) 8-10 MB per album. Opus codec provides best quality at low bitrates (64-128 Kbps for streaming applications).
Image optimization strategies: RAW photos from professional cameras use 20-80 MB, JPEG from same camera 5-15 MB. Vector graphics (SVG) perfect for icons and logos (1-10 KB). PNG for images with transparency, JPEG for photographs without transparency.
Next-generation formats: WebP provides 25-35% size reduction over JPEG with same quality. AVIF offers 50% better compression but limited browser support. HEIF (iPhone photos) provides excellent compression for mobile photography workflows.
⚡ Network Performance and Bandwidth Calculations
Network throughput: Gigabit Ethernet (1 Gbps = 125 MB/s) theoretically transfers 1 GB in 8 seconds. Wi-Fi 6 (802.11ax) reaches 9.6 Gbps = 1.2 GB/s. USB 3.0 provides 5 Gbps = 625 MB/s, USB-C (USB 3.2 Gen2) 10 Gbps = 1.25 GB/s. Thunderbolt 4 achieves 40 Gbps = 5 GB/s.
Storage device speeds: HDD (7200 RPM) reads 100-200 MB/s, SATA SSD 500-600 MB/s, NVMe SSD 3000-7000 MB/s. Copying 100 GB takes: HDD 8-17 minutes, SATA SSD 3 minutes, NVMe 30-60 seconds. For video editing, NVMe drives recommended for smooth 4K content playback.
