Encode text or files into data: URIs (with MIME, charset, base64) and decode them back. Live previews for images/HTML/SVG/JSON, copyable snippets, QR generation, batch decode, and optional minify/sanitize — all local.
A powerful base converter that supports conversions between bases 2–36 (binary, octal, decimal, hex, and more). Features include auto-detecting input base, exact big-int math for integers, fractional support with configurable precision, two’s-complement helper, and bulk mode for converting multiple numbers at once. Runs entirely client-side for speed, privacy, and accuracy.
Convert images to Base64 (with preview) and decode Base64 back to images entirely client-side. Includes copy-ready HTML/CSS/Markdown snippets, line wrapping, automatic MIME detection/validation, and re-export to PNG/JPEG/WebP. Works offline for speed and privacy.
Reduce Base64 image size with client-side compression and resizing. Paste a Base64 string (raw or data URI) or upload an image, preview original vs optimized, adjust quality and dimensions, and copy the optimized Base64 instantly. Supports automatic MIME detection/validation and re-encoding to PNG/JPEG/WebP. Runs offline for speed and privacy.
Convert Hex to ASCII and ASCII to Hex with robust parsing (0x, \xNN, spaces, commas), UTF-8/Latin-1 support, configurable grouping & delimiters, classic hexdump view, MD5/SHA-256/CRC32, entropy, and stats — all client-side.
Convert JSON to CSV and CSV to JSON entirely in your browser. Supports NDJSON, schema detection, flattening nested objects to dotted paths, exploding/joining arrays, delimiter/quote/EOL/BOM options, previews (table/JSON), and fast chunked parsing for large files.
Convert PHP array/object literals to JSON and back — no code execution. Supports short [] and long array() syntax, assoc vs stdClass output, pretty/minify with custom indent, JSONC (strip // and /* */), strict validation with line/column errors. 100% client-side.
data:
URI. Choose base64 or percent-encoding, set MIME and charset, and grab ready-to-use snippets for <img>
, CSS, Markdown, or <link>
. Decode existing data URIs back to text/files, preview safely, and export. Nothing leaves your browser.Tired of bloated tool websites with 10 ads per click? This platform is built for speed, simplicity, and reliability. Whether you're debugging JSON or testing colors, we’ve got your back.
