Pull a JPG or PNG down to a smaller file size for the storefront or email.
The everyday operating tools of a one-to-five-person business: shrink a product photo for the marketplace, generate a QR code for the storefront, check the exchange rate before quoting a customer, generate UUIDs for an import, summarize a competitor blog post, count the words on a product description. Cheap, fast, and your inventory photos never leave your device.
For photos, 70-80% JPEG quality is usually invisible at the size a customer actually views them. Test on your real product photo, not on a sample image - flat backgrounds and fine textures fail sooner than portraits.
PNG is a lossless format, so there is little to squeeze out of it. For photographs, convert to JPEG or WebP first; keep PNG for logos, screenshots and graphics with flat colours.
No. The result is a standard JPEG, PNG or WebP that marketplaces, CMS uploads and email clients accept. Keep the original master file so you can re-export later without compounding the quality loss.
