Frequently Asked Questions

Batch Image Converter Online — Convert PNG to WebP for Faster Websites

Speed is a ranking signal. Google PageSpeed Insights recommends serving images in next-generation formats like WebP and AVIF because they are 25–35% smaller than equivalent JPG or PNG files — which means your pages load faster and your Core Web Vitals score goes up. Our free batch image converter online lets you drop your entire media library and convert PNG to WebP (or JPG to WebP) in one go, without installing software and without sending a single pixel to a server. Whether you run a blog, a WooCommerce store, or a portfolio site, switching to WebP is the lowest-effort performance win you can make today.

A Privacy-Focused Image Tool — Powered by WebAssembly, Not Servers

Most online image tools upload your files to a remote server for processing. That means a stranger's computer holds your photos — even temporarily. Our privacy-focused image tool is architecturally different: it uses WebAssembly (WASM) and the browser's native Canvas API so that every conversion happens inside your own RAM, on your own device. Nothing is ever transmitted. No account is created. No log is written. This makes it safe for sensitive images like business documents, client photos, or personal pictures you'd rather not share with anyone — including us.

Convert HEIC to JPG Free — And Every Other Format You'll Ever Need

iPhone users produce HEIC files by default — a format Windows, most websites, and Android devices can't open natively. Our tool converts HEIC to JPG free, with no file count limits and no watermarks. Beyond HEIC, we support converting between JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, SVG, and ICO. Need a favicon? Convert any image to ICO. Need to compress product photos for your Shopify store? Convert JPG to WebP at quality 85 and cut file sizes by a third. Whatever your workflow, this is the one image tool you'll bookmark.

E-commerce Photography Tips

Preparing Professional Product Images for Amazon, eBay, and Online Stores

1

Pure White Background (RGB 255,255,255)

Amazon, eBay, and most marketplaces require pure white backgrounds for main product images. Use our BG Remover to strip the background, then export here as JPG for direct marketplace upload.

2

Image Compression for SEO & Page Speed

Large image files slow page load times — hurting both conversions and SEO. For your own website, convert product photos to WebP at 85% quality. For marketplace uploads, use JPG at 90% quality. This batch converter handles both scenarios in one workflow.

3

Recommended Formats: WebP vs JPG

Use JPG for Amazon, eBay, and Mercado Libre uploads — they require it. Use WebP for your own website or Shopify store — 25–35% smaller files improve Core Web Vitals and Google PageSpeed scores. Convert your entire product catalog in a single batch.
