Why Users Are Leaving iLovePDF
Cloud Storage Privacy Concerns
iLovePDF uploads your files to third-party cloud servers (AWS/Azure) to process them. If you work with financial records, legal contracts, or medical data, this creates severe data breach liability.
Daily Usage Caps & Paywalls
Free users on iLovePDF frequently hit document count limits, wait timers, and restrictions unless they pay $7-$10/month for a subscription.
Upload & Download Latency
Large 50MB+ PDFs can take minutes to upload and re-download. Hearthhammer processes files instantly on your local computer CPU.
