Instagram Image Resizer

Universal format, best for photos. No transparency.

Resizing runs entirely in your browser — your image never leaves your device.

Instagram Image Resizer

Instagram stores every feed photo at 1080px wide and re-compresses whatever you send it — uploading the wrong size is how sharp photos turn soft. This resizer preloads the 1080px width, keeps your aspect ratio locked, and exports a clean JPG. Everything runs in your browser; your photos stay with you.

Instagram Photo Sizes at a Glance

Feed photos are 1080px wide, in three shapes: square 1080×1080 (1:1), portrait 1080×1350 (4:5 — the tallest feed post that still shows fully without tapping), and landscape 1080×566. Stories and Reels run 1080×1920 (9:16). Profile pictures are 320×320.

Feed the resizer a portrait photo and the 1080px preset lands at 1080×1350 territory automatically — the exact shape Instagram rewards with the most screen space.

Beat the Recompression

Instagram re-encodes every upload, and artifacts multiply when a source is already small or over-compressed. Upload at the exact target size with the quality slider around 90: the platform's pass then starts from clean material instead of magnifying your compression.

Frequently Asked Questions

What size is an Instagram post?

1080 pixels wide. Square posts are 1080×1080, portrait posts 1080×1350 (4:5), landscape 1080×566. The 1080px preset here matches all three — only the shape differs.

What about Stories and Reels?

1080×1920 (9:16). Load the photo, unlock the aspect ratio and type the height, or crop to 9:16 in your camera app first and resize the width here.

Why does my Instagram upload look blurry?

Usually a size mismatch: Instagram resizes anything that isn't 1080px wide, and upscaling or double-compressing softens detail. Supply the exact size at decent quality and the platform has nothing to fix.

Can I resize without cropping?

Yes — the aspect lock keeps the original ratio while scaling, so nothing is cut off. Cropping is a separate creative choice; do it before or after resizing, your call.
