## Pricing

$3.00 / 1,000 image processeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## Bulk Image Converter & Optimizer

Convert, resize, compress, and strip metadata from **many images at once** — to **WebP, AVIF, JPEG, or PNG**. Point it at a list of image URLs; get back optimized images (with download URLs) and a size-savings report. Pure compute on images you supply — **no scraping, no personal data** (in fact, it *removes* EXIF/GPS by default).

This **bulk image converter** is designed for developers and site owners who need a programmable **image optimization API** that scales to thousands of images without queuing, uploads, or manual clicks.

### Use cases
- **Web performance** — bulk-convert a media library to WebP/AVIF and cut page weight 70–90%.
- **Thumbnails / responsive images** — **bulk image resize** to a max width/height in one pass.
- **Format migration** — normalize a mixed folder (PNG/JPEG/legacy formats) to one modern format.
- **Privacy** — strip EXIF/GPS metadata from images before publishing.

### How to use it (quick start)

1. Feed the Actor a JSON array of image URLs via `imageUrls`.
2. Choose your output `format`: `webp`, `avif`, `jpeg`, `png`, or `original`.
3. Optionally set `quality` (1–100), max `width`/`height`, and `fit` behaviour.
4. Run the Actor. Each converted image produces a dataset row with an `outputUrl` you can download directly — no separate storage step needed.
5. Pass the output URLs to a CDN, CMS, or static-site pipeline for immediate deployment.

### Input
`imageUrls` (required) · `format` (webp / avif / jpeg / png / original) · `quality` (1–100) · `width` / `height` (max px, aspect preserved) · `fit` (inside / cover / contain) · `stripMetadata` (default true).

```json
{ "imageUrls": ["https://site.com/a.jpg", "https://site.com/b.png"], "format": "webp", "quality": 75, "width": 1200 }
````

### Output

One dataset item per image: `status`, `sourceUrl`, **`outputUrl`** (download the converted image from the run's key-value store), `format`, `width`, `height`, `originalBytes`, `outputBytes`, **`savedPct`**. Failed fetches/decodes return a structured `error` item (never charged).

### Pricing (pay-per-event) & cost example

| Event | Price | When |
|---|--:|---|
| `image-processed` (primary) | $0.003 | per image successfully converted |

**1,000 images → $3.00.** Measured platform compute + transfer is **well under $0.10** for that batch (<3% of revenue). Failed images are never charged.

As a **bulk image compressor**, this is one of the most cost-effective ways to optimise a media library programmatically.

### Integrate

Chain it after any Actor that outputs image URLs, or call it via the **REST API / MCP / Make / n8n**. Converted files live in the run's key-value store (download via `outputUrl`).

### FAQ

**What image formats can I convert to?** WebP, AVIF, JPEG, PNG, or keep the original format. The default is WebP — the best balance of size and quality for most use cases.

**Can I use this as a bulk image compressor without losing quality?** Yes. At quality=100 there is virtually no visible degradation (especially for WebP and AVIF), but file sizes drop significantly vs. uncompressed JPEGs.

**Does it strip EXIF and GPS data?** Yes, by default. Orientation is applied before stripping so your images look right even after metadata removal. Set `stripMetadata: false` to preserve EXIF if needed.

**Is there a limit on how many images I can process?** No hard limit — you set `imageUrls` to any array length. Processing is billed per-image at $0.003. For very large batches, consider splitting across multiple runs.

**Can I process HEIC images from an iPhone?** Not currently — the prebuilt image engine (sharp/libvips) does not include the patent-encumbered HEIC/HEVC codec. Supported inputs include JPEG, PNG, WebP, AVIF, GIF, TIFF, and SVG; a HEIC URL returns a structured error item (never charged). Convert HEIC to JPEG on-device first.

**How do I download the converted images?** Each dataset row includes an `outputUrl` field — a direct download link to the optimized file in the run's key-value store. You can also chain to another Actor for upload to S3, CDN, or CMS.

**Do I need to upload images?** No — the Actor fetches images by URL. Point it at any publicly accessible image URL; no uploads required.

### Limitations

- Fetches images by **URL** (one polite request each); it does not crawl pages to discover images.
- Output images are stored in the run's key-value store (retention per your Apify plan).
- Animated formats are converted to a single frame unless the target format supports animation.
- Built on **sharp / libvips** (Apache-2.0 / LGPL) — permissive, commercial-friendly.

# Actor input Schema

## `imageUrls` (type: `array`):

Direct URLs of the images to convert/optimize. Each is fetched once and processed.

## `format` (type: `string`):

Target image format. 'original' keeps the source format and only resizes/optimizes.

## `quality` (type: `integer`):

Compression quality for lossy formats (WebP/AVIF/JPEG). Lower = smaller file.

## `width` (type: `integer`):

Resize so width fits within this many pixels (aspect ratio preserved). Leave empty to keep original width.

## `height` (type: `integer`):

Resize so height fits within this many pixels (aspect ratio preserved). Leave empty to keep original height.

## `fit` (type: `string`):

How to fit the image within the given width/height.

## `stripMetadata` (type: `boolean`):

Remove EXIF and other metadata (including GPS) from the output. Orientation is auto-applied first.

## Actor input object example

```json
{
  "imageUrls": [
    "https://example.com/photo1.jpg",
    "https://example.com/photo2.png"
  ],
  "format": "webp",
  "quality": 80,
  "fit": "inside",
  "stripMetadata": true
}
```
