About this tool
Resize pictures to the dimensions X (formerly Twitter) displays best. Headers are a wide 3:1 banner, post images look best at 16:9, and profile pictures are square.
Use the crop option to fill the frame, or fit inside to keep the whole picture visible.
Everything runs in your browser. Nothing is uploaded.
Frequently asked questions
What size should a Twitter header be?
1500 x 500 pixels. Keep key content centered because the profile photo overlaps the lower left.
Can I use a custom size?
Yes. Choose Custom size at the bottom of the size list and type your own width and height.
Will the quality drop?
Pictures are resampled with high-quality smoothing, so they stay sharp. JPG quality can be adjusted.
Is X (Twitter) Image Resizer really free?
Yes. You can use X (Twitter) Image Resizer as often as you like with no sign-up, no watermark and no daily limit.
Are my images uploaded to a server?
No. X (Twitter) Image Resizer runs entirely in your web browser, so your files stay on your own device and are never sent to DEWANARO or anyone else.
