How to Compress Images for Instagram

Instagram automatically compresses images you upload, often reducing quality significantly. By pre-optimizing your images, you maintain control over the final quality that appears on your profile.

Instagram recommends uploading images in JPG format at a maximum of 1080px wide. Their compression is most destructive with oversized files and PNG format.
