Why use Social9
Every edit is made on your device, at full quality, and you don't need an account.
Official sizes
Sizes for Instagram, LinkedIn, X, Facebook, YouTube, TikTok, Pinterest and WhatsApp.
Crop or fit
Crop the photo to fill the frame, or fit the whole photo and fill the space around it with a blur or a color.
The right pixel size
Your photo is saved at the size each platform expects, so it won't be cropped again when you upload it.

Will my photo lose quality?
No. Social9 saves your photo at full quality from the original. You can also set a maximum file size.
Do I need an account?
No. Open the tool and start editing. You don't need to sign up.
