About converters
We provide free online converters for designers and developers: color spaces (RGB, HEX, HSL, CMYK), time zones, Unix timestamps, date and age calculations, QR codes, barcodes, Base64 and URL encoding, MD5/SHA hashes, UUIDs, JSON formatting, HEIC to JPG, and extracting palettes from images. Pick a tool below to get started.
Our converter tools use instant resultswhere applicable. We do not see, store, or transmit your content for those tools. That means faster results and privacy for sensitive inputs.

Frequently asked questions
- What converters are available?
- This hub links to color and time/date converter suites, QR and barcode generators, HEIC to JPG, color palette extraction, Base64 and URL encoders, hash and UUID generators, and a JSON formatter. Open any card to use that tool.
- What color formats can I convert?
- The color converters section supports RGB, HEX, HSL, and CMYK, plus a color picker. RGB and HEX are common for web; HSL helps with intuitive adjustments; CMYK is used for print workflows.
- How do time zone and Unix tools work?
- Use the time & date tools to convert between time zones, translate Unix timestamps to readable dates (and back), add or subtract time from dates, or calculate age from a birth date. Pick the matching tool from the hub.
- Are conversions accurate?
- Yes. Color, date, and encoding conversions use standard formulas and algorithms. For legally or safety-critical use, double-check against authoritative references.
- When should I use HEIC to JPG versus the main image converter?
- Use HEIC to JPG when iPhone exports are still in Apple’s HEIC/HEIF container. Use the general image converter when you already have JPG/PNG/WebP and need cross-format swaps or tuning.
