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.
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.
