Bulk Image Resizer: Resize, Crop, Convert & Compress Images in Bulk

Resize hundreds of images in one run: several sizes per image (thumbnail + web + retina), ready-made sizes for Amazon, Shopify, Etsy, eBay, Instagram, YouTube and favicons, a maximum file size in KB, and JPEG, PNG, WebP or AVIF output. iPhone HEIC photos are read too. Paste links (or Google Drive / Dropbox share links), upload files, or chain it after any scraper. Every file lands in the run's key-value store with a public link, plus one images.zip.

• 📐 Several sizes per image: thumb=300x300:cover, web=1200, retina=2400, 50%... one file per size.
• 🛒 Marketplace and social presets: Amazon 2000×2000, Shopify 2048×2048, Etsy 3000×2250, eBay 1600×1600 (white padding), Instagram square / portrait / story, YouTube thumbnail, Open Graph share image, responsive web srcset, favicon set.
• 🗜️ Max file size target: quality is lowered step by step, then the picture is made smaller, until each file fits (for example under 100 KB). Each record says whether the target was met.
• ✂️ Fit modes: contain, cover (crop with centre, top, bottom, left, right or smart detail-aware position), pad with any colour (exact box), stretch. Never enlarges unless you allow it.
• 🔄 Formats: JPEG (progressive), PNG, WebP, AVIF out; JPEG, PNG, WebP, AVIF, HEIC/HEIF, GIF, TIFF, BMP in.
• 🎨 Colour-correct: photos are turned upright by their EXIF orientation; wide-gamut photos (iPhone Display P3) are converted to sRGB before metadata is stripped, so colours don't shift. Or keep EXIF and the colour profile.
• 📦 Output: public links per file, images.zip with everything, and one dataset row per image.

What can you do with it?

• E-commerce: turn supplier photos into exact marketplace sizes on a white background (Amazon, Shopify, Etsy, eBay).
• Websites: make srcset sets (480/960/1600/2400 px WebP) or thumbnails + full-size images, and shrink them under a KB limit for page speed.
• Social media: crop photos to Instagram square, portrait or story, YouTube thumbnails (under 2 MB) and link previews (1200×630).
• iPhone photos: convert HEIC to JPEG or WebP in bulk.
• Pipelines and AI agents: chain after a product, Instagram or Google Maps scraper with datasetId, or call it from an agent through MCP.

Which files and links does it accept?

Input	Example	Notes
Direct image link	https://example.com/photos/shoe.jpg	JPG, PNG, WebP, AVIF, HEIC/HEIF, GIF, TIFF, BMP
Google Drive file	https://drive.google.com/file/d/.../view	shared as "Anyone with the link"
Dropbox file	https://www.dropbox.com/s/.../photo.png?dl=0	public share link
Uploaded file	"Or upload images" field in the Console	stored in your key-value store
Apify dataset	datasetId + datasetField (e.g. images[*].url)	chain after any scraper

Folders and pages that need a login are not supported: link the files themselves. Animated GIF/WebP: the first frame is used. Up to 50 MB per file.

How much does it cost?

You pay per output image file. One image resized to 3 sizes = 3 files. Dead links, private files and unreadable files are never charged.

Event	Free / Bronze	Silver	Gold / Platinum / Diamond
Image file (image)	$0.0025	$0.002	$0.0015
Actor start (apify-actor-start)	$0.00005 / run	$0.00005 / run	$0.00005 / run

Examples: 1,000 product photos to one Amazon size = 1,000 files = $2.50 (down to $1.50). 100 photos × 3 web sizes = 300 files = $0.75. Set maxImages or a maximum cost per run to cap the spend.

How fast is it?

Measured on Apify at the default 1 GB of memory, with 12–18 megapixel camera photos (4080×3072 and 5184×3456 JPEG):

Job	10 photos	Per photo
One 1200 px WebP each	7.6 s run	under 1 s
Three sizes each (300 cover, 1200, 2400 WebP)	20 s run	~2 s
Amazon 2000×2000 JPEG on white	6.9 s run	under 1 s
1600 px WebP under 100 KB (quality search)	12 s run	~1 s

Downloads run four at a time while the previous photo is processed. At the default 1 GB an image can have up to 52 megapixels (32 with transparency); a bigger one is skipped uncharged with a "run with more memory" note. Each extra GB allows ~85 megapixels more, up to 178 megapixels. All sizes of one image together may add up to twice that.

Presets

Preset	Output	Fit
amazon	2000×2000 JPEG q90	pad, white
shopify	2048×2048 JPEG q85	pad, white
etsy	3000×2250 JPEG q90	pad, white
ebay	1600×1600 JPEG q90	pad, white
instagram-square	1080×1080 JPEG q90	cover, smart crop
instagram-portrait	1080×1350 JPEG q90	cover, smart crop
instagram-story	1080×1920 JPEG q90	cover, smart crop
youtube-thumbnail	1280×720 JPEG q90, under 2 MB	cover, smart crop
social-share	1200×630 JPEG q85 (Open Graph, X, LinkedIn)	cover, smart crop
web-responsive	480, 960, 1600, 2400 px wide WebP q80	contain, never enlarged
favicon	favicon.ico (16/32/48) + 180, 192, 512 px PNG	pad, transparent

Marketplace and social presets enlarge small images so the box is always exact. A preset replaces the sizes, fit, format, quality and background fields; "Strip metadata" and "ZIP" still apply.

Input

Field	Default	Description
images		Image links, one per line
uploads		Uploaded files (Console file upload)
datasetId / datasetField	url	Read links from a dataset field (imageUrl, images[*].url...)

outputFormat	same	same, jpeg, png, webp, avif (same: HEIC → JPEG; GIF, TIFF, BMP → PNG)
quality	82	1–100 for JPEG, WebP, AVIF (AVIF is scaled so the same number looks like JPEG at that quality)
maxFileSizeKb		maximum size of each output file

createZip	true	save images.zip with every file
maxImages	100	input images per run

Use the API from code

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("bossless/bulk-image-resizer").call(run_input={
    "images": ["https://example.com/shoe.jpg"],
    "preset": "amazon",
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    for f in item["outputs"] or []:
        print(f["url"], f["width"], f["height"], f["bytes"])

curl "https://api.apify.com/v2/acts/bossless~bulk-image-resizer/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"images": ["https://example.com/photo.heic"], "sizes": ["1600"], "outputFormat": "jpeg", "maxFileSizeKb": 400}'

Use it with AI agents (MCP)

Add https://mcp.apify.com?tools=bossless/bulk-image-resizer to Claude, Cursor or any MCP client. The agent passes image links and a preset or sizes, and gets back public links to the resized files.

FAQ

Does it enlarge small images? Not by default: a small image keeps its own size (with pad it is centred on the exact box). Turn on allowUpscale to enlarge. Marketplace and social presets always produce the exact box.

What does "smart" crop do? It keeps the part of the picture with the most detail (edges), which usually holds the subject, instead of always cutting the centre.

Why is my file bigger than the max size? The quality goes down to 30 and the picture is made smaller up to four times; a file that still doesn't fit is delivered with targetMet: false.

Can it remove backgrounds or read EXIF data? Not this actor. Use Background Remover for transparent cutouts and EXIF Metadata Extractor to read camera, GPS and dates.

Are my images private? They are stored in your run's key-value store under your account; the links work for anyone who has them, like other Apify storage links.

Is this an official Amazon, Shopify, Etsy, eBay, Instagram or YouTube tool? No. This is an independent tool and is not affiliated with or endorsed by Amazon, Shopify, Etsy, eBay, Meta/Instagram, Google/YouTube or Apple. The presets follow their published image size guidelines.
