Compression tips for a 500 KB cap

Half a megabyte is tighter than a 1 MB cap: you will resize more often, lean on WebP, and accept slightly lower quality on photos. This page targets email signatures, legacy form fields, and hosts that reject chunky uploads.

  • 500 KB ≈ 50% of a 1 MB budget—plan to resize wide screenshots first
  • WebP often saves 30–40% vs JPEG at similar visual quality

Step-by-step for 500 KB

Upload, pick WebP or JPEG, and lower quality until the preview shows under 500 KB. If text in a screenshot looks soft, resize width to the display size instead of crushing quality further.

When 500 KB is the wrong target

Print assets, 4K wallpapers, and RAW exports need far more headroom. Use the under 1 MB guide or the main compressor when your limit is closer to one megabyte.
