Online PDF tools vs desktop software: which should you use?
By Mergevanta · Updated · 1 min read
Quick answer
Should I use an online PDF tool or desktop software?
Use an online tool for quick jobs like merging or converting files: it runs in any browser with nothing to install, and the good ones are free and keep no copies. Use desktop software if you edit PDFs every day, need OCR, forms or redaction, or must process very large files offline.
