This is the most common question. Let’s separate ethics from practicality.
The Ethical Side: Isaac is a single-player game. Using a 100% save file does not affect leaderboards (there are none), violate any EULA (End User License Agreement), or harm other players’ experiences. Many veterans use save files to test mods, speedrun specific bosses, or recover lost progress. It is not considered cheating by the developer—Edmund McMillen has even joked about "save file sharing" being a form of community mercy.
The Safety Side: Crucial warning. Never download a random .dat file from a sketchy "free game saves" website. Many of these contain malware or adware. Stick to trusted sources like: The Binding Of Isaac Repentance 100 Save File Download

In the Isaac community, downloading a 100% save file is a polarizing topic. This is the most common question
The Purists argue: "The point of Isaac is the journey. You haven’t ‘beaten’ the game if you didn’t suffer through 500 failed Lost runs. You’re robbing yourself."
The Pragmatists argue: "It’s a single-player game. If you’ve already beaten the game on Switch or console and just want to play on PC, why redo the grind? Time is valuable." We will provide a verified, clean download source
Our take: If you have never played Isaac before, do not download a 100% save. Play blind. The discovery of a new item or a hidden floor is the magic of the game.
However, if you are on your third platform, or you lost your save to a hard drive crash, or you simply want to design mods—downloading a The Binding of Isaac: Repentance 100% Save File is a perfectly reasonable quality-of-life tool.
