GUIDES
BulkCrunch guides
From no-upload batch compression to quality vs max edge. HEIC, metadata strip, and watermarks stay in sibling tools.
Batch-compress JPG/PNG/WEBP locally (no upload)Pick many files, compare before/after sizes, download singles or a ZIP. Honest contrast with TinyPNG’s free web limits.
How to choose quality and max edgeJPEG/WEBP slider, PNG re-encode, and when a max edge is the real lever.
Image too large to upload? Compress locally firstTune quality and max edge when forms reject big files—no invented MB caps.
JPG vs PNG vs WEBP when batch-compressingChoose by use case; compression changes quality/edge, not just the extension.
Need a no-upload TinyPNG-style batch?Upload tools vs browser-local; competitor limits per their pages.
Suggested order
Read the no-upload batch guide first, then quality. If the source is HEIC, start at Heiclocal. For less location baggage before you share, use Metastrip. For marks, use Stampdrop.
