Image Converter vs JWT Decoder
conversion
Image Converter
Convert images between PNG, JPEG, WebP, AVIF, TIFF, GIF, and SVG formats
Upload an image and convert it to another format. Supports PNG, JPEG, WebP, AVIF, TIFF, GIF as both input and output; SVG is accepted as input only. Maximum input size is 3 MB. Returns the converted image as a base64 string along with dimensions and file size.
Example input:
{
"image": "<base64-png>",
"from": "png",
"to": "webp",
"quality": 80
}encoding
JWT Decoder
Decode and verify JSON Web Tokens — header, payload, claims, and signature.
Paste a JSON Web Token to instantly decode its header and payload. Optionally supply a secret or public key to verify the signature.
Example input:
{
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"
