Ecom Image Optimizer
Optimize product images for every marketplace
Heavy product photos are one of the biggest causes of slow online stores, and slow stores lose sales. This free tool turns oversized camera and phone photos into lightweight, correctly-sized images ready for your store or marketplace, without the quality loss you would get from a careless resize.
Drop in one image or a hundred, pick a preset, and export store-ready files in seconds. No account, no watermark on the output, no file-count paywall.

- Resize to exact dimensions or fit/pad to a target box.
- Compress to a target file size or quality, with high-quality resampling.
- Convert between JPEG, PNG, WebP and AVIF, or export several formats at once.
- Watermark with text or a logo, and clean watermarks from your own images.
- Batch process and rename whole sets consistently.
- Add image SEO metadata (alt text, structured-data snippets) on export.
Supported formats & limits
Upload JPEG, PNG, WebP or AVIF, up to 50 MB each and 100 files per batch. Export to WebP or AVIF for the smallest files, or JPEG/PNG when a marketplace requires it. Modern formats like WebP typically cut file size by more than half versus JPEG at the same visual quality.
Sizes for every sales channel
Marketplaces enforce image rules. Break them and the listing is suppressed. Store platforms only recommend. These guides cover both, with a preset that produces compliant files:
Marketplaces
- Amazon image requirements: pure-white background, 1000 px+ for zoom, no watermarks.
- Etsy listing photo sizes: 2000 px+ for sharp listing photos and thumbnails.
- eBay image sizes: 1600 px on the longest side to enable zoom.
E-commerce platforms
- Shopify image sizes: square 2048×2048 WebP for fast, zoomable storefront photos.
Frequently asked questions
What does an e-commerce image optimizer do?
It prepares product photos for online stores and marketplaces: resizing them to the right dimensions, compressing them so pages load fast, converting them to modern formats like WebP and AVIF, and optionally adding watermarks or SEO metadata, all in repeatable presets so every image comes out consistent.
Which format is best for product photos: WebP, AVIF, JPEG or PNG?
WebP is the best all-round choice for storefronts: widely supported and noticeably smaller than JPEG at the same quality. AVIF compresses further and suits hero banners. Use JPEG where a marketplace requires it, such as Amazon main images, and PNG only when you need transparency or a lossless source.
How much can I reduce file size without losing quality?
For typical product photography you can usually cut 80–95% of the file size with no visible difference, by resizing to the dimensions you actually display and exporting to WebP or AVIF. You can set a target file size or quality to control the trade-off precisely.
What happens to my images when I use this tool?
Your images are sent over an encrypted connection to our server, processed, and returned to you. They are not retained after processing and are never shared with anyone. See the privacy page for details.
What file types and sizes can I upload?
JPEG, PNG, WebP and AVIF, one or many at a time, up to 50 MB each and 100 files per batch. Output format, dimensions and compression are all configurable.
Can I optimize many product images at once?
Yes. Add a whole batch, apply a preset, and export them together, with consistent dimensions, format and file naming across the set.
Will optimizing images help my store’s SEO and Core Web Vitals?
Lighter images are one of the most effective ways to improve Largest Contentful Paint and overall page speed, which Google measures as Core Web Vitals. Faster product pages tend to rank better and convert more visitors.
Do I need an account or to pay?
No. The tool is free and requires no signup. Open it and start optimizing.
