Upload Metadata
What to uploadUpload all the .json files from your NFT metadata folder. Each file represents one NFT — usually named 0.json, 1.json, 2.json etc. These are the files that contain your token name, description, traits and image URL.

IPFS Configuration
What is IPFS?IPFS is a decentralised storage network used to host NFT images. After uploading your images to a pinning service like Pinata, you get a CID — a unique hash that points to your folder. This tool updates your metadata to reference that CID.
New IPFS CID Required
From Pinata, NFT.Storage, IPFS Desktop, etc.
Fields to Update Select
Which fields to updateThese are the keys inside your JSON files that hold image URLs. Most collections only need "image". Enable animation_url only if your NFTs have a separate video or audio file hosted on IPFS.
✓
image
→ ipfs://CID/0.png
animation_url
video/audio only
external_url
custom URL
For standard image collections, image is all you need. Only enable animation_url if your NFTs include video, audio or interactive files.
Options
Advanced optionsThese control how the tool handles edge cases in your metadata. Safe to leave as default for most collections — the settings below explain what each one does.
Preserve old URL as backup field
Backup original URLWhen enabled, the tool saves the original URL into a new field called "original_image" before overwriting it. Useful if you want a record of where the images were previously hosted.
Saves original in "original_image" etc.
Skip files with no existing URL
Skip empty filesIf a JSON file doesn't already have an image field, this option prevents the tool from adding one. Recommended to keep this on — it avoids accidentally modifying clean or unusual metadata files.
Don't add empty fields to clean files
Use token ID as filename
Token ID namingWhen on, the tool uses each file's token ID as the image filename — so token 0 points to ipfs://CID/0.png, token 1 to ipfs://CID/1.png etc. This is the standard for almost all NFT collections. Only turn off if your images use custom filenames.
ipfs://CID/0.png, 1.png…
