What is the best size for an Instagram post?
Instagram recommends 1080×1350 pixels (4:5 portrait) for feed posts because it occupies the most vertical screen space and aligns with the 3:4 grid. Square 1080×1080 still works but takes less feed real estate.
What size should an Instagram story or reel be?
Stories and reels are full-screen vertical at 1080×1920 pixels (9:16 aspect ratio). Keep important content within the central 14% safe zone to avoid being covered by the profile and reply UI.
Will Instagram compress my image after upload?
Yes. Instagram compresses every upload, so it is best to send a properly cropped, sharp image at the recommended dimensions. Cropping in the browser before upload preserves the most quality.
Is this Instagram image cropper really private?
Yes. Cropping happens entirely on your device using the Canvas API. Your image is never uploaded to a server, never tracked, and never stored. Open your network tab and confirm - there are no upload requests.
Should I export as PNG or JPG for Instagram?
Use JPG for photographs to keep the file size small. Use PNG for graphics with text or transparency. Instagram supports both.
