Why this tool is different

This is a review-first batch workflow: select destinations, adjust each crop independently, encode locally, and inspect measured dimensions and bytes before downloading.

Requirements and recommendations

How to prepare a social image batch

  • Choose up to 20 JPG, PNG, or WebP images.
  • Select one or more verified destination presets.
  • Use Fill or Fit, position, and zoom for every planned variant before processing.
How OpenFileTools processes it

Local processing, explicit choices.

OpenFileTools decodes each source once in the browser, keeps crop state per image and destination, and encodes ordered JPG variants sequentially. Files can be downloaded alone or in one ZIP.

Frequently asked

Questions, answered.

Are these dimensions official requirements?

Only presets labeled official recommendation or requirement come directly from first-party guidance. Convenience targets are labeled separately.

Do all variants share one crop?

No. Each image and destination combination has independent position, zoom, Fit or Fill, and reset controls.

Are images uploaded?

No. The current workflow processes image bytes in this browser tab.
