Resize Image for Instagram — Free Online Tool

Resize any photo for Instagram — square posts (1080×1080), portrait posts (1080×1350), or stories and reels (1080×1920) — for free, right in your browser. Drop a JPG or PNG, type the Instagram dimensions you need, and download the resized image instantly. The tool keeps aspect ratio if you choose, or fits to exact pixels with smart cropping. Resizing happens 100% client-side, so your photos never leave your device — safe for personal photos, brand assets, and influencer content. Use it before posting to avoid Instagram’s aggressive automatic compression, which can blur images that aren’t pre-sized. Pre-resized images keep more sharpness, color accuracy, and text legibility on feed.

Frequently asked questions

What is the best image size for Instagram posts?

Instagram uses 1080×1080 for square posts, 1080×1350 for portrait, and 1080×1920 for stories and reels. Always export at these exact pixel sizes for sharpest results.

Why do my photos look blurry on Instagram?

Instagram re-compresses uploads. Pre-resizing to 1080px wide and saving at high JPEG quality avoids most blur.

Can I crop a portrait photo to a 1:1 square?

Yes — set width and height both to 1080 and the tool will crop centered. Use the crop tool first if you want to control framing.

Does Instagram support PNG?

Yes, but PNGs are converted to JPG on upload, so saving as JPG yourself gives a more predictable result.
