About the HEIC Converter API
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11. While it offers great compression, many platforms don't support it. This API converts HEIC to universally supported formats like PNG, JPG, or WebP.
Ways to call it
One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

Request parameters — POST /v1/heicconverter
Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.
Required
| Parameter | Type | Example | Description |
|---|---|---|---|
imageRequired | string | Upload a HEIC or HEIF image file to convert | |
outputFormatRequired | string | png | Target formatpngjpgwebpgiftiff |
Optional
| Parameter | Type | Example | Description |
|---|---|---|---|
qualityOptional | integer | 90 | Output quality (applies to jpg/webp) default 90 · range 1-100 |
maxWidthOptionalPremium | integer | 1920 | Maximum width in pixels (maintains aspect ratio) range 1-10000 |
maxHeightOptionalPremium | integer | 1080 | Maximum height in pixels (maintains aspect ratio) range 1-10000 |
curl -X POST "https://api.apiverve.com/v1/heicconverter" \
-H "x-api-key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"outputFormat":"png","quality":90,"maxWidth":1920,"maxHeight":1080}'Authentication
Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.
| Header | When | Value |
|---|---|---|
x-api-keyRequired | Every request | Your API key. Header names are case-insensitive, so X-API-Key is the same header. |
AuthorizationAlternate | Instead of the above | Bearer <key> — for clients that only expose bearer auth. Resolves to the same account and the same billing. |
content-typeRequired | POST body | application/json |
A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.
Response — POST /v1/heicconverter
Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.
{
"status": "ok",
"error": null,
"data": {
"id": "f8e7d6c5-4321-09ab-fedc-ba0987654321",

Response fields
Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.
| Field | Type | Example | Description |
|---|---|---|---|
id | string | "f8e7d6c5-4321-09ab-fedc-ba0987654321" | Unique conversion task identifier |
inputFormat | string | "heic" | Original image format (HEIC or HEIF) |
outputFormat | string | "jpg" | Converted image output format |
inputSizePremium | number | 3145728 | Original image size in bytes |
outputSizePremium | number | 892456 | Converted image size in bytes |
mimeType | string | "image/jpeg" | MIME type of converted image file |
expires | number | 1707350400000 | Download URL expiration timestamp (milliseconds) |
downloadURL | string | "https://storage.googleapis.com/apiverve/heicconverter/f8e7d6c5.jpg" | Temporary download URL for converted image |
Response headers
Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.
| Header | What it carries |
|---|---|
x-api-remaining-credits | Credits left in the current cycle |
x-api-credits-used | Credits spent in the current cycle |
x-api-max-credits | The allowance for the cycle |
x-api-version | Version of the endpoint that answered |
Errors
Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.
| Status | Meaning | What to do |
|---|---|---|
400 | Input was rejected | Read error; it names the parameter that has to change. |
401 | Key missing or invalid | Check the header name and the key value. |
403 | Key valid, but not permitted here | A key restriction or an IP allow-list — never a bad key. |
429 | Rate limited, or out of credits | Read error to tell them apart, then back off or top up. |
What a call costs — 10 credits per call
Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.
| Plan | Per month | Credits | HEIC Converter calls | Per 1,000 calls |
|---|---|---|---|---|
| Free | Free | 200 | 20 | Free |
| Starter | $29.99 | 200,000 | 20,000 | $1.50 |
| Pro | $99.99 | 1,000,000 | 100,000 | $1.00 |
| Mega | $299.99 | 4,000,000 | 400,000 | $0.75 |
Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
Call it from cURL — POST /v1/heicconverter
No SDK to install — this is a plain HTTPS call to /v1/heicconverter with your key in the x-api-key header. Swap in a real key and it runs as-is.

Zero-code embed — one snippet, no backend
Drop an interactive HEIC Converter form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.
Changelog — HEIC Converter API
Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
Entries are picked up from dated catalog snapshots, so the first one appears after the next snapshot that moves something. A period where nothing changed produces no entry — silence is a valid changelog for the HEIC Converter API.
