Resize an image to 1080×1080 for Instagram
1080×1080 is the standard Instagram square feed-post resolution. This preset opens the image resizer pre-configured for that exact output — you drop in any source photo, we downscale to 1080×1080 with high-quality bicubic filtering, and you download the result. Everything happens in your browser via the Canvas API, so the photo is never uploaded. Supports PNG, JPG, WebP, GIF and most browser-decodable formats up to 50 MB.

Common use cases for Resize an image to 1080×1080 for Instagram

Common pitfalls and how to avoid them
- Output looks soft — You upscaled past the source size. Downscaling is lossy-but-sharp; upscaling always softens. Use AI Upscaler (ships later) for large growth.
- Aspect ratio got squished — Toggle "Lock aspect ratio" before editing. If the image is already distorted, crop first with Image Cropper.
- PNG saves bigger than the original — PNG is lossless, so resized PNGs with complex gradients can grow. Switch the output to WebP or JPG for a smaller file.
When should I use Resize an image to 1080×1080 for Instagram?
Choose Image Resizer when you need a specific output size. For shrinking file weight without changing dimensions, use Image Compressor. To resize many images at once, use Bulk Resize, which applies the same target to a folder of files.
Does Instagram still post at 1080×1080?
Yes — it is the long-standing standard for feed posts. Reels and stories use 1080×1920 (9:16); a separate preset is available for those.
My source is portrait. Will it be squashed?
No. The preset crops to a centred 1:1 region before resizing, preserving aspect ratio. You can drag the crop box before downloading if you want a different region.
What file size does Instagram accept?
Up to 30 MB for feed posts. This preset produces ~200 KB–1 MB JPGs at 85% quality, well under the limit.
Is my file uploaded anywhere?
No. Everything runs in your browser — the file never leaves your device, and there is no server component for this tool.
