How to compress a product photo
- Upload your image (JPG, PNG or WebP) by dropping it above or clicking to browse.
- Lower the quality slider until the file size is small enough while the preview still looks sharp. 75–85% is the usual sweet spot.
- Choose a format — WebP compresses hardest, JPG is the safe universal choice.
- Optionally tick shrink to max 2048 px to cut oversized photos down as well, then Compress and download.
Compress vs resize — what's the difference?
They solve different problems, and web images usually need both:
- Resizing changes the pixel dimensions — e.g. a 4,000 px photo down to a 2,048 px square. Use the image resizer for that.
- Compressing keeps the dimensions but lowers the file weight by re-encoding at a lower quality. That's this tool.
The ideal workflow: resize to the right dimensions for your platform, then compress the result to get it under 1 MB.
Rule of thumb: aim for product images under 1 MB. WebP at ~80% quality usually gets a large photo well under that while looking identical to the original. Use the live preview and file-size readout to find the point where quality still holds.
Why file size matters
Page speed is a ranking and conversion factor: slow-loading images push shoppers away and drag down your search position. Marketplaces like Shopify also render faster when your images are light. Compressing every product photo to under 1 MB is one of the cheapest speed wins available. See the product image size guide for the target sizes per platform.
Frequently asked questions
How do I reduce the file size of a product photo?
Upload it, lower the quality slider until the file is small enough while the preview stays sharp, and download. JPG or WebP at 75–85% typically halves the size with no visible loss.
What is the difference between compressing and resizing?
Resizing changes the pixel dimensions; compressing keeps the dimensions but lowers file size by re-encoding at lower quality. For the web you often do both.
Does compressing reduce quality?
Lossy compression removes detail your eye is unlikely to notice. At 75–85% quality the result usually looks identical to the original. Use the live preview to find the balance.
Why should product images load fast?
Page speed affects conversions and search ranking. Compressing product photos to under 1 MB helps you sell more and rank better.
