5 Fun Facts about Batch Resizing & Converting

Canvas = auto privacy scrub

Drawing to canvas strips most metadata (including GPS). Batch exports leave you with cleaner, lighter files by default.

Metadata purge

One click, ten ratios

Entering only width (or height) keeps each image’s original aspect—wide banners stay wide, tall portraits stay tall.

Shape smart

ZIP is just a wrapper

The files don’t change inside a ZIP. It simply bundles everything so browsers deliver dozens of images in a single download hop.

Bundle trick

WebP can replace two formats

Batching to WebP covers both PNG-style transparency and GIF-style animation—often at smaller sizes.

Format multitool

Same pixels, sRGB finish

Most browsers convert to the sRGB color space on canvas. Batch exports tend to look consistent across devices—even if the originals weren’t.
