.gmd ⇄ .txt, both directions, in batches, with a preview of what is inside the level.
Sprite studio
Open a texture pack and see every single sprite as its own picture. Swap one for your own image — it is resized to the original slot for you.

Run one of the bundled Geometry Dash levels right here. Space jumps, Esc closes the game.

Questions people actually ask
What is a .gmd file?
A .gmd file is a Geometry Dash level export. It holds the level's data plus its name, creator and song. Tools and mods such as GDShare can import it.
What is a .txt level string?
A .txt level string is the raw level text. It usually looks like random letters starting with H4sI… because the game compresses it. It is what tools and modded clients that accept level strings expect, and it is a good plain-text backup of a level.
Is my file uploaded anywhere?
No. There is no server in this app. Your files are read and converted inside your browser tab, and they keep working if you go offline.
Can I convert the other way too?
Yes. Drop a .txt file (or paste level text) and you get a .gmd file, with the level's name, creator and song filled in automatically when the file contains them.
I dropped a file and nothing happened.
Levels convert here; a save file such as CCGameManager.dat is read in the save file reader, and a texture pack opens in the sprite studio. Every room is on the same page — use the menu at the top.
Why is my .txt file so hard to read?
That is normal — level strings are compressed. Open Details on a result and choose Readable text to see the decoded version.
Where did my converted files go?
Downloads go wherever your browser saves downloads. The app also keeps a private copy of your last conversions in this browser's storage (see Saved files) so you can download them again. Deleting them there does not touch your original files.
Drop a .zip, .png or .plist anywhere on this page.
Open a texture pack to see every sprite
Drop a .zip texture pack, a matching .png + .plist pair, or loose sprite images anywhere on this page. Every sprite in the atlas is cut out and shown as its own picture, with its real pixel size.

Replace this sprite
Choose a picture — it is scaled to fit this sprite's slot for you. The rest of the pack is untouched, and you can undo at any time.
Play a level alpha
The bundled Geometry Dash runtime runs here, inside the workspace. Space jumps, Esc closes the game. Nothing to install — and the preview itself is still in alpha.
Saved files 0
Your converted levels stay on this device so you can grab them again later — even offline. Deleting them here never touches your original files.
Save file reader
Drop CCGameManager.dat (or any .dat from Geometry Dash) to read your stats, coins, demons and level progress. The file is only read — nothing is written back.
