Hubs
Structured landing pages that connect tools, samples, and workflows around one theme.
Calculators, numerics, date logic, statistics, and finance tools
Image, audio, and video processing, conversion, and optimization tools
Color, layout, graphics, visual styling, and design helper tools
Writing, cleanup, formatting, extraction, and text analysis tools
Developer utilities, networking, web debugging, and automation helpers
Format, file, archive, unit, and encoding conversion tools
Build an animated GIF from video clips or still images, cut its weight with color reduction, resizing, and compression, and tune playback speed and looping until it fits the delivery budget.
Convert footage between MP4, AVI, FLV, MKV, MOV, and WebM containers, keep CRF and bitrate decisions under control during the re-encode, and batch a whole library under one recorded configuration.
Extract the luminance channel, suppress noise with a recorded radius, compare Sobel, Prewitt, Roberts, and Laplacian operators, tune thresholded edge detection, and reproduce the winning result as an explicit convolution kernel.
Turn a single master photo into correctly sized crops for Instagram, TikTok, LinkedIn, and X, preview caption-safe zones, build split grids and collages, and add clearly named styled variants when the channel voice allows them.
A focused workflow for one workbook or one worksheet: select a range, map headers, convert the cleaned table to JSON, and review source, type, null, and duplicate behavior without expanding into batch ingestion or warehouse delivery.
Capture and replay controlled webhook requests, inspect delivery evidence, and check the receiver HTTPS certificate without treating a valid certificate as proof of business trust.
A plain-text presentation workflow for centering lines and marking selected words, phrases, or patterns while keeping code and data semantics outside the transformation.
Screen a beam or slender member from support case and loading through reactions, section properties, bending and shear stress, deflection, and optional Euler buckling. Use the results for preliminary checking only, not design approval.
Check UUID structure, Semantic Versioning syntax, and URL slug characters with focused evidence, without confusing a valid format with uniqueness, availability, or release compatibility.
Turn a source clip into a short ringtone, preview the cut, and check loudness and silence before moving the file to a device.
Check ISBN, UPC/EAN/GTIN, and carrier tracking identifiers for supported formats and available check digits before a catalog or shipment handoff.
Preserve the original PDF hash, compare it with a trusted reference checksum, verify embedded signatures, and record certificate-chain findings without treating tool output as legal validity or proof of signer identity.
