Upload your photo and set the compression slider to 50%. For most JPG photos this reduces file size by 60–80% with no perceptible quality difference on screen. The tool uses optimised JPEG encoding that targets areas the human eye is least sensitive to — smooth backgrounds, gradual gradients — while preserving sharpness on faces and product textures.
For photos with lots of fine detail (product close-ups, food photography), use lower compression (30–45%) to preserve more detail. For photos displaying at small sizes — social media thumbnails, blog previews — higher compression (60–75%) is safe and unnoticeable at thumbnail dimensions.
Photo Compression for Different Platforms
Website photos: target 100–300KB per photo at 50–65% compression. Instagram: compress to 60–70% before uploading to prevent double compression artefacts. Email campaigns: keep images under 100KB — large images cause slow loading on mobile.
Amazon product photos: use 45–55% compression to stay sharp while keeping files under 500KB. WordPress media: keep originals under 1MB by compressing before uploading — your theme generates smaller versions automatically. After compressing, you can also remove product photo backgrounds free.
