  1. Why browser compression helps
  2. Practical size targets

Large photos slow landing pages, clog email threads, and waste mobile data. Compressing images before upload keeps visual quality while cutting kilobytes that do not help the reader.

Why browser compression helps

Client-side compressors process files locally, which is faster for privacy-sensitive screenshots and product photos. You choose a quality target, preview the result, then download a smaller file ready for CMS upload.

  • Open Image Compressor and select a JPG or PNG.
  • Lower quality gradually until the file size fits your budget.
  • Download the compressed image and verify it still looks sharp on a phone.
  • Pair with Image Resizer when dimensions are larger than you need.

Practical size targets

Hero images often land under a few hundred kilobytes after resize plus compress. Thumbnails can go smaller. Always test on a real network throttle instead of trusting desktop Wi-Fi alone.
