PNG vs JPG vs WebP for Exact File-Size Limits

A hard KB limit behaves differently across formats. JPEG and WebP expose lossy quality controls, while PNG often needs pixel reduction or a format change to hit very small limits.

Think in destinations, not repeated exports

Start from the original files and define each destination as an output. This preserves one source of truth and reduces repeated uploads, repeated cropping and naming mistakes.

Keep the preset editable

Platform guidance and upload rules can change. Treat presets as a starting point, then verify the current destination requirement before a large export.

  • Keep the original source files
  • Preview at least one output
  • Use separate folders or filename tokens for each destination

Generate all variants in one batch

Batch Img Tools lets one source batch branch into several output recipes. Each output can have its own dimensions, fit mode, format, compression, metadata, naming and folder.
