Developer tools that never upload your files

Paste an SVG, get a Vue 3 SFC — with props passthrough, currentColor theming and id prefixing.

Code generation

Decode dozens of JWTs at once — header, payload, exp/nbf scan, CSV export. Tokens never leave the browser.

Security & keys

One image in, a whole icon set out: favicon.ico, every PNG size, apple-touch-icon, a maskable icon, site.webmanifest and copy-paste markup.

Images

Paste an OpenAPI or Swagger spec and get typed Vue 3 composables and SFC components — no CLI, no install, nothing uploaded.

Code generation

Turn PDF pages into PNG or JPEG at the DPI you choose — all pages, a range like 1-3,7, or odd/even. The file never leaves your browser.

Documents

Check a Vite .env against .env.example: missing, extra and empty variables, duplicate keys, and secrets you accidentally exposed to the client.

Data & config

Paste your text and the parts you want to match — get ranked regex candidates, each verified against your own text before it is suggested.

Data & config

Convert between PNG, JPEG and WebP in any direction — batch, resize, quality, ZIP. Decoding and encoding happen in your browser.

Images

Base64, Base64URL, URL, HTML entities, hex, binary, \uXXXX escapes, ROT13 and naming styles — batch, with the equivalent command line for every step.

Security & keys

SHA-1/256/384/512, MD5, HMAC, CRC32, file hashing, AES-GCM, password strength and TOTP — offline, in one page, each step with its command line.

Security & keys

Format, validate and convert JSON, YAML, XML and TOML — keeping the comments other formatters throw away, with errors located to the line.

Data & config

Drop your dist folder: per-chunk sizes, real gzip, entry vs lazy, and which chunk blows the budget — without uploading your build.

Code generation

Tick what your project needs and get a clean vite.config.ts — aliases, dev proxy with rewrite and ws, build target, manual chunks — plus the install command.

Code generation

Paste vite.config.ts and package.json: a plugin imported but never installed, a define value that is not stringified, an empty envPrefix, an es5 target — found before your build runs.
