Image Optimizer & Converter: WebP, AVIF, JPG

Compress images, resize them and convert to WebP, AVIF, JPG or PNG in bulk. Image Optimizer & Converter takes image URLs or uploads and returns smaller, web-ready files: shrunk to fit your max width/height (never enlarged), optionally squeezed under a target file size in KB, with EXIF and GPS location data removed and phone photos rotated upright. Every result has a direct download link and before/after sizes. $0.002 per image, failed images are free. A simple image compression API for websites, shops, n8n/Make/Zapier automations and AI agents via the Apify MCP server.

What can this image compressor and converter do?

• 🗜️ Compress images with modern encoders (libwebp, AVIF, mozjpeg, palette PNG). Typical savings: 60–95% for camera photos (a 14.7 MB photo became ~165 KB WebP in our test).
• 🔄 Convert image formats: JPEG, PNG, WebP, AVIF, GIF (first frame) and TIFF → WebP, AVIF, JPEG, PNG, or keep the original format.
• 📏 Resize to fit inside maxWidth × maxHeight, keeping the aspect ratio. Small images are never upscaled.
• 🎯 Target file size: set targetMaxKB (e.g. 500) and the Actor finds the highest quality that fits, shrinking slightly if needed. Rows report targetMet.
• 🔒 Privacy: stripMetadata (on by default) removes EXIF, GPS, camera and XMP data; each row says whether the original had GPS.
• 📱 Auto-rotate from EXIF orientation, and flatten transparency onto a background color when converting to JPEG.
• 📦 Bulk: up to 1,000 images per run.
• 🛡️ Safe downloads: only public http(s) URLs; private/loopback/link-local/cloud-metadata addresses are blocked, with size and time limits.

Who is it for?

• Website owners, shops and bloggers converting product photos to WebP/AVIF for faster pages and better Core Web Vitals.
• No-code automations (n8n, Make, Zapier) that must meet upload limits like "under 500 KB" or "max 2000 px".
• AI agents (via Apify MCP or API) that need a smaller or web-friendly copy of an image before uploading, emailing or embedding it.

How to convert images to WebP in bulk

1. Click Try for free (or Start) and sign in to Apify.
2. Paste image links into Image URLs (or upload files).
3. Choose Output format (WebP is the default) and, optionally, Max width and Target max file size.
4. Leave Strip metadata on to remove GPS location.
5. Click Start. The Output tab lists each file with outputUrl and how much space was saved.

Input example

{
  "imageUrls": ["https://upload.wikimedia.org/wikipedia/commons/3/3f/Fronalpstock_big.jpg"],
  "outputFormat": "webp",
  "maxWidth": 1600,
  "targetMaxKB": 300,
  "stripMetadata": true
}

This optimizes 1 image = $0.002.

How much does image compression cost?

What you do	Images	Price
1 photo → WebP	1	$0.002
500 product photos → WebP, max 1600 px	500	$1.00
1,000 images	1,000	$2.00

Event	Price	When
image-optimized	$0.002	One optimized file was saved and is downloadable.
apify-actor-start	Apify's tiny standard start fee	Once per run.

Failures are free, and runs stop cleanly at your maximum charge per run. Apify's free plan includes monthly platform credit, enough to try it many times.

Use with AI agents (Apify MCP server)

Load just this tool from the hosted Apify MCP server:

https://mcp.apify.com?tools=bigaceboy/image-optimizer-converter

{
  "mcpServers": {
    "image-optimizer": { "url": "https://mcp.apify.com?tools=bigaceboy/image-optimizer-converter" }
  }
}

Then ask: "Convert these product photos to WebP under 300 KB, max 1600 px wide, and remove the GPS data." The agent sends imageUrls, outputFormat, maxWidth, targetMaxKB and reads outputUrl.

Use with n8n, Make and Zapier

• n8n: Apify node → Actors → Run an Actor and Get Dataset → Actor bigaceboy/image-optimizer-converter, input { "imageUrls": ["{{ $json.imageUrl }}"], "outputFormat": "webp", "maxWidth": 1600 }, then upload outputUrl to WordPress, Shopify, S3 or Google Drive.
• Make: Apify → Run an Actor (wait for finish) → Get Dataset Items → map outputUrl.
• Zapier: Apify → Run Actor (synchronous), then use outputUrl.

Use with the API (curl, JavaScript, Python)

curl -X POST "https://api.apify.com/v2/acts/bigaceboy~image-optimizer-converter/run-sync-get-dataset-items" \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"imageUrls":["https://upload.wikimedia.org/wikipedia/commons/3/3f/Fronalpstock_big.jpg"],"outputFormat":"webp","maxWidth":1600}'

import { ApifyClient } from 'apify-client';
const client = new ApifyClient({ token: process.env.APIFY_TOKEN });
const run = await client.actor('bigaceboy/image-optimizer-converter').call({ imageUrls: ['https://example.com/photo.jpg'], outputFormat: 'webp', maxWidth: 1600 });
const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items.map((i) => [i.outputUrl, i.savedPercent]));

from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("bigaceboy/image-optimizer-converter").call(run_input={"imageUrls": ["https://example.com/photo.jpg"], "outputFormat": "webp", "maxWidth": 1600})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["outputUrl"], item.get("savedPercent"))

FAQ

WebP or AVIF: which should I choose?

WebP works in every modern browser and is fast to encode. AVIF is usually 20–30% smaller at the same visual quality but slower to encode. If unsure, use WebP.

How do I compress an image to under 500 KB (or 100 KB)?

Set targetMaxKB: 500. The Actor lowers quality step by step down to minQuality, then shrinks dimensions slightly if still needed. Check targetMet in the output.

Does it remove GPS location from photos?

Yes, by default (stripMetadata: true). Each row reports hadGps for the original.

Will it make my images bigger?

It never upscales. If an original is already very well compressed, the new file can be slightly larger; the row shows both sizes so you can keep the original.

Does it support HEIC or SVG?

Not right now. Convert HEIC on the phone first; SVGs are vectors and don't need this.

Can I keep the original format and only shrink it?

Yes, set outputFormat: "keep" (GIF becomes PNG, TIFF becomes JPEG).
