Format, file, archive, unit, and encoding conversion tools
Take messy tabular data to analysis-ready — merge source tables into one, strip the byte-order marks that break column matching, keep only the columns you need, fix spellings and formats, handle outliers by policy instead of panic, scale or standardize the numbers, and finish with range limits and a crosstab summary.
Furnish a bare spreadsheet into a workbook people can use without asking you questions — upgrade the legacy file, fill formulas down with the cells locked, name the ranges, gate inputs with validation dropdowns, let conditional formatting flag outliers, freeze the headers, build the index sheet, and set the workbook up to print.
Rescue a damaged PDF, strip what should not travel with it, and cut its weight — repair broken headers and cross-reference tables with diagnostics, export annotations before erasing them, remove metadata and form fields, then downsample and recompress to hit your size target.
Take any pile of PDF pages to a clean, printable document — straighten orientation and trim scan edges, delete or extract the pages that matter, unify every page to one paper size, choose color or grayscale for the printer, then add a cover and impose a booklet when the job is bound.
Send PDFs you can prove are yours — redact sensitive content permanently before sealing, add a visible signature block and a PAdES certificate signature, stamp the document status, embed invisible per-recipient tracking IDs, and audit incoming signatures down the certificate chain.
Take a pile of mixed audio files to one shippable library — find and judge duplicates, convert the whole batch to a single format with deliberate encoder settings, fix the CBR or VBR bitrate policy, repair tags and filenames in bulk, and correct playback speed without touching pitch.
Break clean text on purpose — filter, duplicate, and reverse sentences and words, inject random letters and symbols, shuffle lines and words, and prove every mutation stays controlled for parser stress tests, OCR rehearsal, and language experiments.
Dress a finished image with material character — mask where the effect applies, add film grain or surface texture, overlay geometric patterns, and extend the composition with water reflections.
Decide what happens to the sound inside a video — repair noise and loudness, normalize to the EBU R128 delivery standard, replace a licensed music track, or strip audio entirely for silent delivery.
Add prefixes and suffixes to text lines or words, wrap every value in quotes or backticks for SQL, config, and Markdown, and strip inherited numbering, bullets, and decoration from pasted lists.
Convert between bits, bytes, and the decimal SI prefixes KB, MB, GB, TB plus the binary IEC prefixes KiB, MiB, GiB, TiB with the system of every number pinned down before you calculate.
Tune PNG bit depth, palette, and transparency, choose progressive or baseline JPEG loading, dial WebP quality modes, and compress TIFF for archives until every image fits its destination.
