Resize & Optimize Product Photos at Scale
Uploading product images to Shopify, Amazon, or Etsy requires specific dimensions, file sizes, and formats — and the requirements differ across every platform. Manually resizing hundreds of SKUs is tedious and error-prone. Glopix lets you batch resize, compress, convert, and watermark product images in minutes — completely free, no account required.
Purpose-built features for your workflow — not generic tools stuffed into a dashboard.
Resize entire product catalogues at once. Shopify wants 2048×2048 px, Amazon requires 1000 px minimum on the longest side, Etsy recommends 2000 px — set it once, apply to thousands of images.
Heavy product images kill page speed and hurt conversion rates. Compress JPGs and PNGs by up to 90 % with no visible quality loss — fast loading on any device.
Product photos shot on iPhone arrive as HEIC files that most e-commerce platforms can't read. Batch convert to JPG automatically before any other step.
Protect catalogue images from being used by resellers or scrapers. Add a logo watermark to all images in one pass before uploading to any sales channel.
All tools run in your browser — drag, click, download.
Step-by-step — from raw files to ready-to-use output.
