Frequently asked questions

What does Text ↔ binary converter do?

Convert text to binary (8-bit) and decode binary back to text.

When would I actually use this?

Finding out how big a thing will be before you make it: how many gigabytes an hour of footage takes, how long a file needs on the connection you have, how large a photo prints before it goes soft, what bitrate fits the budget you were given.

What is the most common mistake?

Reading a figure in one unit next to a figure in another. Megabits are not megabytes and the eight-fold gap sinks most transfer estimates; a kilobyte is 1 000 bytes to a drive maker and 1 024 to the operating system; pixels are not dots per inch. None of it is hard arithmetic — the unit on each side is what decides whether the answer means anything.

How is Text ↔ binary converter different from Binary to text converter?

They sit next to each other but answer different questions. Binary to text converter: decode 8-bit binary back into readable text (spaces between bytes are optional). Pick whichever matches what you're starting from — both are free.

Where do the figures come from?

Byte prefixes follow the IEC convention where a kibibyte is 1 024 bytes and a kilobyte is 1 000 — drive makers use the second, operating systems often report the first, and a disk that shrinks on arrival is that gap and nothing else. Print sizing assumes 300 dpi unless you change it.

ExplainerFrame Rates, Timecode, and the Drop-Frame That Drops NothingFrames = duration × rate is trivial until the rate is 29.97. Non-drop timecode then drifts exactly 3.6 seconds an hour. Drop-frame corrects it by skipping 108 frame numbers — the same 108 — but the correction is not perfect: counting every frame shows a residual of 3.6 milliseconds per hour.ExplainerHow Big Is That Audio File?Uncompressed audio size is exact arithmetic: sample rate × bit depth × channels × seconds ÷ 8. CD audio is 176,400 bytes per second. A 320 kbps MP3, by contrast, is bitrate × duration and does not depend on the sample rate at all — 2,400,000 bytes a minute whether it came from 44.1 or 48 kHz.ExplainerPrinting A4 on Letter Shrinks It to 94 %A4 and US Letter differ by 5.9 mm one way and 17.6 mm the other, so "fit to page" scales the whole document to 94 %. Ten-point type becomes 9.4, and a plan drawn to scale is wrong by six per cent.ExplainerWhat Is Aspect Ratio? 16:9, 4:3 and How to Compute ItAspect ratio is the proportion of width to height. Learn what 16:9 and 4:3 mean, how to compute a ratio from pixel dimensions, and where each ratio is used.ExplainerSixty Thousand Divided by the Tempo, and Everything Else Is a FractionAt 120 BPM a quarter note lasts 500 ms, an eighth 250 and a dotted eighth 375. One division produces the whole table, and the dotted eighth is the one that changed how delay pedals are used.ExplainerWhat an Availability Percentage Actually AllowsThree nines sounds like a promise until you divide it into minutes. What 99.9 % buys per year, per month, per week and per day; why the measurement window matters far more than the extra nine; and the two different months this tool uses for the same slug.
