Audio, Video & Publishing

Reproduce decimal video-file size from documented video/audio bitrates, duration and explicit container overhead, then compare an independent file-size record.

Reproduce and compare active square-pixel sample counts, decimal megapixels and axis ratios for two explicit reviewed raster records.

Reproduce media-set capacity from a reviewed inventory, per-item payload, explicit working overhead and reserve, then compare an independent capacity record.

Reproduce reviewed square-pixel active-image geometry for a documented target canvas using an explicit Fit/Pad or Fill/Crop mode and rounding rule.

Reproduce a strictly sequential render or export queue from two named completed work-and-elapsed-time observations, explicit fixed overhead, and an independent duration record.

Count words, Unicode characters, sentences and paragraphs. Inspect English readability, estimate reading time and compare a selected publishing length rule.

Estimate reading or narration time from your own effective words-per-minute rate, with optional page estimates using your chosen word density.

Live Markdown editor with real-time HTML preview. Supports headings, bold, italic, links, code blocks, tables, and blockquotes.

Generate scan-testable URL, email, phone, WiFi, or escaped vCard QR codes with UTF-8 capacity checks, color warnings, raster logos, PNG, and SVG.

Calculate whole-pixel image dimensions with a locked ratio or independent width and height, then compare scale and pixel area before exporting in an editor.

Preview sRGB colors with adjustable color-vision models. Compare palettes and text pairs, check original contrast, and copy the simulated colors as CSV.

Compare a measured sample or true peak with a chosen ceiling, or calculate peak-to-RMS crest factor using compatible digital levels.

Calculate byte-aligned PCM payload and explicit overhead from sample rate, stored sample width, channels and duration. Compare bytes, MB and MiB.
