Pre-size and compress so Instagram's re-compression doesn't blur your photos.
Optimising images for Instagram means balancing quality against size. Shrink44 gives you a quality slider, an exact KB/MB target, and resolution capping to get it right.
Everything runs locally via the Canvas API, so your photos are never uploaded — and you can batch 1000+ at once.
Compress your file in under a minute — 100% in your browser.
