PDF Candy
Lays out the PDF Candy toolbox, showing which of merging, converting, OCR, and signing is good enough for what, and where the free tier's file-size and task limits actually bite.
PDF Candy collects the usual PDF chores into browser tools: merging, splitting, compressing, converting to and from Office formats, OCR on scans, editing, signing, and locking. Coverage looks at where the free tier stops, how well OCR handles poor scans, whether batch jobs hold up on large files, and how the desktop version differs from the web one.
