See How VidyBack WorksHeavy images do more damage than eating storage. On most ecommerce product pages, images account for the majority of the bytes a shopper downloads, so they decide how quickly the page appears. Google uses page speed and Core Web Vitals (especially Largest Contentful Paint, which is usually your main product photo) as ranking signals. Slow pages also convert worse: mobile shoppers on patchy connections leave within a few seconds if the product image hasn't loaded. A 4 MB photo straight off a camera can take longer to download than the rest of the page combined.
Compressing and resizing before you upload fixes that at the source. A typical DSLR or phone photo shrinks by 80–95% with no difference a shopper would notice.
| Format | Best for | Notes |
|---|---|---|
| WebP | Product photos, lifestyle shots | Usually 25–35% smaller than JPG at the same visual quality, and it supports transparency. Supported by all modern browsers and Shopify. |
| JPG | Product photos where maximum compatibility matters | Universally accepted. Some marketplaces, feeds and older systems still expect JPG. No transparency. |
| PNG | Logos, graphics, cut-outs that need a transparent background | Lossless, so photos saved as PNG are often 5–10× larger than JPG/WebP. Avoid PNG for regular photos. |
Aim for under 200–300 KB per image for fast-loading product pages. For dimensions, about 2048 px on the longest side is plenty (it's what Shopify recommends for square product images and it still supports zoom). Tick “Resize large images” in the tool above and set 2048 px. Then pick a quality of 75–85 and check the result in the before/after slider. If the savings figure is above 70%, you've probably removed a lot of dead weight.
At sensible settings, no visible quality is lost. A quality setting of 70–85 for JPG or WebP usually removes 60–90% of the file size while the photo looks identical on a product page. Below about 50, artifacts such as blockiness and color banding start to appear, especially on smooth backgrounds. Use the before/after slider to check each image before downloading.
For photos, use WebP or JPG. WebP is usually 25–35% smaller than JPG at the same visual quality, and Shopify accepts it. Use PNG only for graphics that need a transparent background, such as logos. Shopify recommends 2048 × 2048 px square images for product photos, so there is rarely a reason to upload anything larger.
No. All compression, resizing and format conversion happens inside your browser using the built-in Canvas API. Your photos never leave your device, and there is no signup, watermark or usage limit.
Aim for under 200–300 KB per product image for fast-loading product pages. Hero or zoomable images can go a little higher, but anything over 500 KB is usually worth compressing or resizing.
