Resize Image to 1080×1080 Pixels
1080×1080 is the standard square post size on Instagram and a safe default for square social graphics anywhere. Uploading at exactly this size means the platform's own recompression has the least work to do, keeping your image as sharp as possible. PNGful resizes in your browser, free, with nothing sent to a server.

PNG for graphics and transparency, JPG for photos, WebP for the web.

Common uses
- Instagram square feed posts at the platform's native 1080×1080
- Square carousel slides with consistent dimensions
- Social graphics reused across platforms that favor squares
- Profile grid previews and content calendar mockups
Good to know
- Photos straight from a camera or phone are not square: crop to fill for an edge-to-edge post, or fit with padding to keep the entire frame — white or blurred-background padding is a popular Instagram look.
- Instagram recompresses every upload. Starting from a clean 1080×1080 file avoids double-scaling, which is where most visible quality loss on the platform comes from.
- Don't upscale a small image to 1080×1080 for posting — enlargement cannot add detail, and Instagram's compression makes soft images look worse. Post smaller originals at their native size instead.
- Export photos as JPEG at high quality; PNG suits text-heavy graphics, though Instagram converts uploads to JPEG anyway, so avoid fine one-pixel details.

Frequently asked questions
Is 1080×1080 still the correct Instagram post size?
Yes — Instagram serves square feed images at up to 1080 pixels wide, so 1080×1080 remains the size to export. Larger uploads are simply scaled down to it, and smaller ones are scaled up, which costs sharpness.
How do I make my photo square without cutting anything off?
Use fit mode: PNGful scales the full photo into the 1080×1080 canvas and fills the remaining space with padding. You keep every pixel of the original at the cost of bars on two sides — a look plenty of accounts use deliberately.
Why do my Instagram posts look blurry after uploading?
Usually double compression: the app resized your image to 1080 wide and then recompressed it. Uploading a file already at 1080×1080, exported at high JPEG quality, gives Instagram nothing to resize and minimizes the visible damage.
Can I use 1080×1080 for other platforms too?
Yes. Square posts at 1080×1080 work well on Facebook, LinkedIn, and X, all of which display square images without cropping in feeds. It is a practical single export when you cross-post the same graphic.
Does resizing here compress my image as well?
The resize itself just changes pixel dimensions; the file is then encoded at high quality, which usually shrinks it because 1080×1080 has fewer pixels than a camera photo. It all happens locally in your browser, and the original file is untouched.
