Pokemon HeX runs entirely in your browser — no installation, no signup, and your save file never leaves your device. This guide walks you through a complete edit, from dumping your save to putting it back.
1. Export your save file
You need a decrypted save file:
- 3DS / Switch: dump the save with a save manager such as Checkpoint, JKSM, or SaveDataFiler.
- Emulator: use the
.savor.dsvfile directly. - Encrypted backups from devices like Powersaves are not supported.
No save at hand? The editor ships with built-in example saves for Generations 1–8, so you can explore the editor first.
2. Open the save in the editor
Open the online editor and drag the save file onto the page (or use the file picker). The save is parsed locally by the PKHeX.Core engine compiled to WebAssembly — nothing is uploaded.
3. Edit your data
- Pokémon: click any slot to edit its nickname, form, nature, ability, IVs/EVs, moves, shininess, Poké Ball, and more.
- Boxes: use the batch tools to heal a box, make everything shiny, sort, or remove duplicates.
- Items, Pokédex & trainer: manage bag items, complete the Pokédex, and edit trainer name, money, play time, and badges.
4. Check legality
Every Pokémon is validated against real encounter data as you edit. Invalid Pokémon are flagged instantly, and you can legalize them with one click — or scan all boxes at once to spot problems.
5. Export and import back
Review the change log and the diff against your original save, then export the file. Restore it to your console with the same save manager you used in step 1 (or copy it back to your emulator) and keep playing.
