Small tools.
Big vibes.

Turns iPhone HEIC photos into PNGs or JPGs that the rest of the internet can actually open. Drag in up to 50 files. Works offline after first load. Zero iCloud involvement.

Format, minify, sort keys, and validate JSON. Tree view for spelunking. Keyboard shortcuts for the keyboard people. Catches most of the common errors and tells you exactly where they are.

Drop an image, get a color palette. Exports as CSS variables, SCSS, Tailwind config, Figma tokens, or plain JSON. The color names are generated from the actual colors. They are sometimes correct.

Make SVG files small without making them look bad. Strips editor metadata, rounds coordinates, removes useless attributes. See the byte count drop in real time. Side-by-side visual check. Satisfying.

Write a regex, see matches highlighted live, and get a plain-English explanation of what every piece of it actually does. Handles the escapes, the lookarounds, the weird character classes. Find-and-replace mode too.

QR codes for URLs, WiFi credentials, contacts, emails, SMS, or just text. Customize the colors, drop a logo in the middle, download PNG or SVG. The WiFi password never goes anywhere near our server.

Drop one image, get every favicon size you need — 16, 32, 48, 180, 192, 512 — plus a multi-resolution .ico and the HTML snippet for your head. One ZIP, one minute. Then never think about favicons again.

Paste two versions of anything — code, prose, config, logs — and see exactly what changed. Line-by-line with word-level highlights. Split or unified view. Export as a standard unified patch.

Convert between JSON, YAML, TOML, CSV, TSV, XML, Markdown tables, HTML tables, and SQL INSERT statements. Any format to any other. Type coercion, handles nested data, gets the quoting right. 72 directions, one tool.

Paste any timestamp — Unix epoch (seconds or milliseconds), ISO 8601, RFC 2822, or almost any human-readable date — and see every other representation at once. Timezone-aware, DST-correct, live clock. Math, diffs, copy-per-row.

Stitch images into PDFs, or slice PDFs back into images. Drag, drop, reorder, download. Client-side, 50 MB cap, honest about what it can't do. Word docs stay on your Word.

Paste broken JSON. Get fixed JSON back. Trailing commas, unquoted keys, Python-style True, truncated payloads — it fixes what's safe, refuses what isn't, and tells you every change it made.

Describe a pattern in English, get a regex back — with test cases and explanation. On-device AI via Chrome's built-in Prompt API or WebGPU fallback. No upload, no server.

Paste any cron expression, get plain-English meaning plus the next 5 trigger times. 12 timezones, full crontab syntax including / , and -. Validates before it explains.

Encode text or files to Base64, decode Base64 back, preview data URLs. URL-safe and MIME-wrap variants. Images, PDFs, and text all render a live preview.

Paste a JWT. See the header, payload, and signature decoded — all client-side, never sent anywhere. Live countdown on exp claims. Flags alg=none and other security footguns.

Shrink PDFs by re-encoding images to JPEG. Quality slider, DPI target, settings saved between visits. Your PDF never leaves your browser. Tell it nothing, it tells you no secrets.

UUID v4, UUID v7, ULID, Nanoid. Single or batch up to 1000. Decode existing IDs to pull out embedded timestamps. All sourced from crypto.getRandomValues — the same CSPRNG your browser uses for TLS.

MD5, SHA-1, SHA-256, SHA-384, SHA-512. Text or files up to 2 GB, streamed in 2 MB chunks so your tab doesn't freeze. Hex or Base64 output, hash-compare mode for verifying downloads. Input never leaves the page.

Every HTTP status code on one page, with what it means, when to use it, and the real-world pitfalls. Searchable and filterable. Deep-linkable — /http-status/#404 jumps straight to 404.

Drop a .ico file and see what's inside — every image at every resolution, dimensions, bit depth, BMP vs PNG blobs, AND masks, CUR hotspots. Byte-level hex dump with field annotations. Extract individual images as PNG. Browser-only.

Write Markdown on the left, see the rendered preview on the right. GFM tables, task lists, strikethrough, and auto-highlighted code blocks. Export as HTML, copy the rendered output, or print straight to PDF. Your document never leaves this page.

URL percent-encoding, HTML entity encoding, and case conversion (camel, snake, kebab, Pascal, constant, dot, path) — three panels in one page. The daily encoding tasks you keep looking up, done in your browser.
