Why there's no upload step
Instagram's feed posts are commonly sized 1080×1080 for square posts. Uploading an unresized photo lets Instagram's own algorithm crop it, which can cut off exactly the part you wanted visible. Resizing it yourself first — locally, without uploading it anywhere else — gives you control over the framing before it ever reaches Instagram.
Is my photo uploaded anywhere?+
No. Resizing happens entirely in your browser — nothing touches a server before you post it yourself.
Does this work for Stories or Reels too?+
This preset targets the square feed-post size. For portrait formats like Stories (1080×1920), use the custom width/height fields on the tool.
Will my photo look stretched?+
No — aspect ratio is preserved, so your photo fits inside the square rather than being distorted.
What format is the output?+
JPG, which Instagram accepts directly.
