How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
80 KB is a sensible weight for the main photo of a product in a shop listing. A catalogue of hundreds of items loads well when every picture stays near this size.
The tool picks the highest quality that fits under 80,000 bytes. On a plain white background the file shrinks easily, so the picture often keeps most of its pixels and loses only a little quality.
Product pictures are judged on edges and colour. Edges tell the buyer about the shape, and colour tells them about the material, so protect both and let the background take the loss.
Why white backgrounds help
A flat white background is the cheapest thing a compressor can describe, because every block of it is identical. A product on white at 1000 pixels across often fits in 80 KB with room to spare, while the same product on a patterned tablecloth would not.
WebP for catalogues
For product shots, WebP is often the better choice. It keeps crisp edges with fewer artefacts around the outline, and the same 80 KB buys a visibly cleaner picture. Choose it in the Format menu and compare with JPEG using the sizes shown.
Colour accuracy
Buyers return items that look different from the picture. Heavy compression does not shift hues, but banding in smooth gradients, like a glossy bottle, can make a product look cheap. If you see bands, raise the target to 100 KB for that picture.
Consistent sizes in a grid
A grid of product pictures looks best when all of them share the same dimensions. Crop each to a square or a fixed ratio, set the same width in Resize, and compress to 80 KB. The grid will line up and load evenly.
Lifestyle photos versus cut-outs
A product in a room has more detail than a cut-out and will need a larger target. Treat 80 KB as the size for the clean main picture, and give lifestyle shots 150 KB or more.
Colour profiles and white backgrounds
A white that is not quite white shows as a faint grey box on a white page. Check the corners of your product picture before you compress. If they look off-white, fix them in an editor first, so the picture blends into the page.
After compression, open the result on a plain white page and look for a visible edge.
A workflow for a whole catalogue
For a catalogue with many products, set up a routine: crop, same width, compress to 80 KB, then inspect ten pictures chosen at random. Checking a sample catches most problems before the pictures reach the shop.
If the sample shows a fault, change the setting and run the whole set again.
Frequently asked questions
What size in pixels suits a product page?
Between 800 and 1200 pixels on the long side covers most layouts, including zoom on the product itself.
Can I keep a transparent background?
Yes, with PNG or WebP. Use the background tool first if you want to remove a background.
Why does my picture have bands in the shadows?
Smooth gradients are hard to compress. Raise the target a little or lower the pixel size.
Is there a limit to how many I can do?
You can add many files at once and process them with the same target.
Is a smaller product photo always better?
No. Past a point, shoppers see the loss. Stop at the smallest size where the material and edges still look right.
Do I need to resize before compressing?
It helps. A product picture shown at 800 pixels does not need a 4000 pixel original, and reducing it first lets the compressor spend its 80 KB on pixels that count.
