Compress product photos for an online shop
Heavy product photos slow down shop pages, and some marketplaces limit upload sizes. Camera and phone photos are often several megabytes each.
Compress Image re-encodes JPG, PNG and WebP files at the quality you choose while keeping the format and pixel dimensions. Before and after sizes are shown side by side, and everything runs in your browser.
Example: twenty 4 MB phone photos of handmade jewellery. Add them all at once, compress them together, and upload the lighter versions to your listings. Pages that show many products, such as category grids and search results, benefit the most because every image on them has to download before the page feels complete, especially for shoppers browsing on mobile data.
Compression doesn't resize images. If the store recommends a particular pixel size, resize in your photo editor first, then compress. Camera and location metadata is removed during re-encoding, which is a sensible default for photos you publish. If an image is already well optimised, you get the original back rather than a larger file.
Step by step
- Open Compress Image and add all your product photos (up to 50 MB each).
- Pick a quality setting.
- Compress and compare the before and after sizes.
- Download them and check a few at full size before uploading to your store.
Tips
- Use JPG for photos and PNG for graphics with sharp edges or transparency.
- Convert JPG or PNG to WebP for even smaller files if your platform accepts WebP.
- Keep originals for print and future edits.
Questions
- Will the format change?
- No. A JPG stays a JPG, a PNG stays a PNG and a WebP stays a WebP.
- Are image dimensions changed?
- No. Only the file size changes.
- Is location data kept?
- No. Camera and location metadata is dropped during compression.
