Softnag is an open, privacy-centric web utility platform designed to solve daily digital tasks — from image optimization and PDF manipulation to developer encoding and math calculations — without paywalls, forced registrations, or server uploads.
For years, common online file converters and developer tools have suffered from severe usability issues:
Most online converters require uploading sensitive PDFs, confidential contracts, or private family photos to third-party cloud servers with unknown retention policies.
Softnag performs conversions directly within your browser's memory using HTML5 Canvas, WebAssembly, and modern Web APIs. Your files never leave your device.
Many online utilities lure users in, only to slap a watermark, demand a paid monthly subscription, or cap file sizes after a single use.
Every utility is fully featured and free without artificial daily limits, watermarks, forced signups, or subscription locks.
Rather than maintaining centralized processing clusters that ingest user files, Softnag leverages modern browser standards to run complex computations on your own device:
crypto.getRandomValues() and crypto.subtle for cryptographically secure, uncrackable randomness.Compress, resize, crop, convert, and optimize images directly in your browser with zero server uploads.
Merge, split, rotate, extract, compress, and convert PDF documents locally on your device with complete privacy.
Format, validate, encode, hash, inspect data, and test regex securely using standard client-side browser APIs.
Generate high-entropy passwords, decode JWTs, calculate cryptographic hashes, and inspect data securely in your browser.
Count words, convert casing, compare diffs, remove duplicates, sort lists, and generate clean dummy copy.
Calculate percentages, loan EMIs, GST sales tax, exact age, and convert universal units instantly.
Quickly format JSON, decode JWTs, generate UUIDs, encode URLs, test regular expressions, and compute cryptographic hashes during active development.
Compress WebP images, crop social banners to standard aspect ratios (16:9, 1:1, 9:16), extract color palettes, and generate website favicons instantly.
Merge lecture notes into single PDF files, count words/characters for essays, calculate age/grades, and maintain focus with the Pomodoro study timer.
Split documents, add watermark security to sensitive reports, calculate GST and loan EMIs, and convert CSV data tables safely on confidential local machines.
