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
Turn a background-removed image into a checked target-size canvas by choosing a suitable edge treatment and reviewing the boundary before delivery.
Check supported passport, SSN, driver's license, VIN, and license plate patterns before a form or record moves forward, while keeping the result limited to format evidence.
Organize soil, groundwater, geometry, loading, and drainage assumptions before screening shallow-foundation capacity, infinite-slope stability, and Rankine active earth pressure. Calculator output is preliminary only.
Check credit-card, IBAN/SWIFT, EU VAT, and US EIN strings against syntax, length, country rules, and applicable checksums without treating a format pass as proof of account or registration status.
Protect files and selected data fields, open encrypted PDFs with authorized credentials, set or remove permissions, and verify reversible output and reader compatibility.
Generate or reproduce a file hash, compare it with a published checksum, and verify a detached Ed25519 signature with a separately trusted public key.
Generate or convert cron expressions, validate semantics, visualize upcoming runs, and test them against an explicit trigger window.
Prepare a preliminary concrete mix per cubic metre and a separate reinforcement spacing or bar-count check. Keep units, material assumptions, cover and spacing constraints, constructability, and local code review visible. Calculator results are not a stamped structural design or site safety approval.
Check email, phone, and postal code syntax with country or region context for single values and batches, while keeping format results separate from deliverability, reachability, and address existence.
Plan and verify recurring meetings across time zones, workdays, holidays, conflicts, and ICS export requirements.
Prepare a consistent image set by correcting orientation, removing unwanted margins, applying one size policy, compressing files, and checking representative outputs before delivery.
Map silence in dialogue or recordings, trim only the boundaries that should go, compress internal pauses deliberately, and add measured space with an audible before-and-after check.
