PDF Candy offers over forty PDF tools covering conversion, editing, merging, splitting, compression, OCR, and more. The interface groups tools by category, making it easy to find what you need. There's also a desktop version for Windows that works offline. The online tools are free with no registration required, though there are file size limits and some tools are restricted to a certain number of uses per day.

The site is supported by ads, which are noticeable but not overwhelming. Conversion quality is generally good, and the range of supported formats is broad. It's a useful resource when you need to handle a PDF task and don't want to install software or pay for a subscription. For occasional use, the free tier is more than adequate.
