Product pages with images that load in under 1 second have 2x higher conversion rates than those loading in 5+ seconds (Google/SOASTA, 2017). Yet the median ecommerce page ships 5.7MB of images (HTTP Archive, 2024). SizeMyPic lets you batch-compress, resize, and convert product photos in your browser — no upload to third-party servers, no per-image fees.

Supports JPEG, PNG, WebP, and SVG
Amazon requires JPEG/PNG, minimum 1000px on the longest side, and recommends 2000px for zoom. Shopify recommends 2048x2048px. eBay caps uploads at 12MB. Instead of manually resizing each photo, drop your entire product shoot into SizeMyPic, set target dimensions, and batch-export in the right format. Aspect ratio lock prevents cropping distortion.
A 1-second delay in page load reduces conversions by 7% (Akamai, 2017). Product images are usually the heaviest assets on ecommerce pages. Converting from PNG to WebP cuts file size by 26% (Google), and dropping JPEG quality from 100 to 82 reduces size by 60%+ with no visible difference on product photos. SizeMyPic's quality slider lets you find that threshold per batch.
A 50-SKU catalog with 5 angles each means 250 images. SizeMyPic handles batch processing without file-count limits. Set your dimensions and format once, process everything, and download a ZIP. File names are preserved, so you can upload directly to your store's media library.
Most online image optimization services charge per image or per month. SizeMyPic is free with no limits. Process 10 images or 1,000 — same cost: zero.
Pre-launch product images are sensitive. SizeMyPic processes everything in your browser using the Canvas API. Nothing is uploaded to any server. Your unreleased products stay confidential.
No software to install. SizeMyPic runs in Chrome, Firefox, Safari, and Edge on desktop and mobile. Process images from a warehouse laptop, a home office, or a phone at a trade show.
For storefronts you control (Shopify, WooCommerce), use WebP — it's 25-34% smaller than JPEG with equivalent quality, and supported by 97%+ of browsers (CanIUse). For marketplaces (Amazon, eBay, Etsy), use JPEG — it's universally accepted and most marketplaces don't support WebP uploads yet.
Amazon: minimum 1000px, recommended 2000px on the longest side for zoom. Shopify: recommended 2048x2048px. eBay: minimum 500px, recommended 1600px. For your own store, 1200-1600px wide covers most layouts and retina displays. SizeMyPic's aspect ratio lock lets you set the long edge and auto-calculate the other dimension.
JPEG quality 80-85 is the sweet spot for product photography. Below 75, compression artifacts become visible on detailed textures (fabrics, jewelry). At quality 82, a typical 3MB product photo compresses to 400-600KB with no perceptible quality loss on screen. For WebP, quality 80 produces even smaller files at the same visual fidelity.
