How to Convert PNG to JPG for Shopify
Your Shopify store accepts the PNG without complaint, but then your product pages feel sluggish, your Lighthouse score drops, and a single gallery is weighing in at tens of megabytes. The culprit is usually PNG product photos — Shopify allows them, but they're far heavier than they need to be. Converting those PNGs to JPG before you upload makes your store noticeably faster.
How to convert PNG to JPG for Shopify
QuickWand's free PNG to JPG converter runs in your browser, so nothing is uploaded to a server.
- Open the PNG to JPG converter.
- Drag your
.pngproduct photos into the drop zone, or click to browse. Add an entire collection at once. - Choose JPG as the output format and set quality to about 85–90% — sharp enough for product galleries, small enough to load fast.
- Click Convert, then download each JPG or use Download all (.zip) to upload the whole set to Shopify.
Why JPG is better for a Shopify store
Shopify accepts a wide range of formats — JPEG, PNG, PSD, TIFF, BMP, GIF, SVG, HEIC, and WebP — at up to 5,000 x 5,000 pixels and under 20 MB. But its own guidance is clear: use JPG for product images, banners, and slideshows, and reserve PNG for graphics and transparency. The reason is performance. A JPG product photo is a fraction of the size of the same PNG, and lighter pages load faster, rank better, and convert more shoppers.
You also don't need to worry about uploading WebP yourself. Shopify's image service automatically serves your photos as WebP or AVIF to browsers that support those formats — so a clean JPG upload gets the speed benefits of WebP delivery without the compatibility headaches.
A note on transparent PNGs
Converting a transparent PNG to JPG will fill the transparent areas with a solid background, since JPG cannot store transparency. For most product photos on a white storefront that's fine. But if you use cut-out images that need to sit over a colored section or a banner, keep those as PNG (or use them through Shopify's media that preserves transparency) and only convert the standard photos.
Squeeze them smaller, or fix WebP files
For even lighter pages, run your JPGs through the free image compressor and watch the live size estimate as you adjust quality. And if a supplier or stock site hands you .webp files, the WebP to JPG converter turns them into editable JPGs first.
