Utilities · fourteen tools
Tools that keep
your files yours.
your files yours.
Fourteen things that do one job each. Nine of them work entirely in the page without sending anything anywhere — the photos, the conversion, the disk search, the metadata, the hidden characters — because a tool that has to upload your file first is a service, not a utility. The five that do use the network say exactly what leaves.

Deadline
The countdown ledger
Equinoxes, solstices, full moons, clock changes and tax day counted down on the page, with your own dates kept in your browser.
Courier
Send a file, browser to browser
A file goes straight between two browsers over WebRTC with no server in between, and SHA-256 at both ends proves it whole.
Diff & Crate
Compare two files, open a zip
Compare any two files — texts by line and word, images by slider and pixel heat — and open a zip, all without sending anything.
File Search
Find anything on your own disk
Search a folder on your own disk by name, content, size, date and type, and find duplicates, with nothing uploaded.
OmniFile
Any format in, the one you need out
Files, a folder or a ZIP read for what their bytes say they are, then converted in the tab by Canvas and FFmpeg, never uploaded.
File Share
A link and a QR code that expire
A short link and QR code for any file up to 2.24 GB, expiring in one to 72 hours, with an optional password and no account.
Search
Sixteen live feeds, one box
Wikipedia, Hacker News, Stack Exchange, arXiv, GitHub and more at once, with quick answers and a handoff to seven assistants.
Glass
Every byte of a photo, read
A photo’s JPEG markers, PNG chunks and EXIF fields read by hand with their hex offsets, plus forensic views and a clean copy.
Watermark
The characters you cannot see
Eight detectors read pasted text character by character for invisible controls, lookalike letters and bidi tricks, with offsets.
Paper Tape Calculator
Eleven tools printing to one receipt
Standard, scientific, programmer, loans, dates, units and more on one running tape, where any line can be reused or exported.
VIN Decoder
Seventeen characters, read
Any VIN decoded the way NHTSA reads it, with the check digit worked out, the model’s recalls and complaints, and the EPA’s MPG.
MPG Lookup
What the EPA says a car burns
The EPA’s city, highway and combined MPG for any car since 1984 by year, make, model and engine, read live from fueleconomy.gov.
Darkroom
Photos, cleaned before you send them
Read what a photo carries, strip it without re-encoding a pixel, then convert or resize a batch, all without an upload.
PDF
Merge, split and reorder, no upload
Merge files, pull out pages by range, rotate, reorder and delete them in your browser, where they stay; nothing is uploaded.
