Convert an image to 1:1 ratio (square)
A 1:1 ratio means equal width and height — a perfect square. It is the native shape for Instagram feed posts and is also the safest, most universally accepted shape for profile pictures and avatars across almost every platform, since square crops rarely get cut off awkwardly by a circular or rounded mask.

How to convert your image to 1:1 ratio
Upload your image using the tool above.
If your photo is wider than tall, crop mode will trim equal amounts from the left and right edges to center the subject — or switch to pad mode to add a white border instead of cutting anything.

Why do you need to convert to 1:1 ratio?
The square format is the most universally accepted image shape across the web. Instagram's feed was built around it, every major platform accepts a square profile photo without any awkward cropping, and app stores require square icons. If you only pick one safe format to standardize your images on, 1:1 is it.
Common pixel sizes for this ratio (1:1)
Where this ratio is used
- Instagram and Facebook feed posts
- Profile pictures and avatars (Twitter/X, LinkedIn, Discord, WhatsApp)
- App icons and favicons
- Album covers and podcast cover art
Crop or pad — which should you use for this ratio?
For 1:1, cropping is almost always the right choice — most source photos are wider or taller than square, and trimming the long side evenly keeps the subject centered the way Instagram and profile-picture crops expect. Reach for padding only when a wide group photo has people right at the left or right edge that cropping would cut out.
How this ratio compares to a similar one
1:1 vs 4:5: 1:1 is the safer pick for anything that might display as a circle or get cropped automatically (profile photos, avatars, icons), since a perfect square crops predictably from any direction. 4:5 is better when the photo is going specifically into the Instagram feed and you want more vertical room than a square allows.
Frequently asked questions
Will cropping to 1:1 cut off parts of my photo?
If your original photo is wider or taller than square, the crop mode trims the longer side evenly from both edges by default. Use pad mode instead if you need to keep every pixel of the original — it adds a background border instead of cutting anything.
What size should I use for an Instagram profile picture?
Instagram displays profile pictures at 320×320 px but recommends uploading at 1080×1080 px so it stays sharp on high-resolution screens and when zoomed.
Does a square crop work for app icons?
Yes — most app stores require a square master icon (commonly 1024×1024 px) and apply their own rounded-corner or circular mask on top of it automatically.
Can I use 1:1 for a YouTube channel banner?
No — YouTube channel art uses a much wider ratio (roughly 16:9 for the safe area within a 2.7:1 canvas). 1:1 is for square placements like profile photos and feed posts, not wide banners.
Does converting to 1:1 reduce image quality?
Cropping or padding alone doesn't reduce quality — the tool only removes or adds pixels around the edges. Quality only drops if you scale the result up well beyond the original photo's resolution.
