How the resizer works
Pick a preset and the preview becomes a canvas of exactly that size. Your image is first fitted inside it whole, without cropping, and any empty space is filled with white. From there you can:
- zoom with the slider or the mouse wheel to fill the frame (this crops the edges that fall outside);
- drag the image with a mouse or a finger to choose which part stays in view;
- turn the image left or right in 90 degree steps;
- press Fit Image to return to the whole image centred.
The export is rendered at the preset's full pixel size from your original image, not from the smaller preview, and saved as a WebP file at quality 0.92.
The header shares space with your profile picture
On profile pages, your round profile picture overlaps the lower-left part of the header, and the visible area changes between phone and desktop layouts. Keep text and key details in the centre and right of the header, and avoid putting anything important in the bottom-left corner or right at the top and bottom edges.
Posts in the timeline
Images in the timeline may be shown cropped to fit the layout until someone taps them, especially when several images are posted together. A 16:9 image with the subject near the centre is the safest choice for a single image. If your photo is tall, consider whether the cropped preview still shows what matters.
Export notes
- Format: the download is WebP. If a platform or scheduling tool rejects WebP uploads, convert the file with WebP to JPG.
- Background: any area your image does not cover is white. To use a coloured background instead, zoom in until the image fills the frame.
- Metadata: EXIF data, including GPS location, is not included in the exported file.
- Platform compression: social networks usually re-compress uploads. Exporting at the preset size avoids an extra resize on their side, but the final quality is still up to the platform.
The preset sizes above are the values built into this tool. Platforms change their layouts and recommendations from time to time, so if an upload looks cropped unexpectedly, check the platform's own help pages for the current size and use the Crop tool and Image Resizer to match it.
Where the processing happens
The image is processed locally in your browser and nothing is posted or uploaded.
Questions about this tool
My X header looks cut off. How do I make it fit?
Choose Twitter / X Header (1500 x 500). Keep text and important details in the centre and on the right, because your round profile picture covers the lower-left part.
My photo is shown cropped in the timeline. Which size avoids that?
Use the Twitter / X Post preset (1200 x 675) with the subject near the centre. A 16:9 image is the safest shape for a single image in the timeline.
Which size should my X profile picture be?
Choose Twitter / X Profile (400 x 400) and centre your face or logo. It is shown as a circle, so leave space at the corners.
Why are there white bars around my photo?
Your photo has a different shape from the X frame, so the tool fits the whole photo inside and fills the rest with white. Move the zoom slider up until the photo fills the frame, then drag it to choose which part stays in view.
The app will not accept the downloaded file. What do I do?
The download is a WebP file. Most platforms accept it, but if one does not, convert it with WebP to JPG and upload the JPG.
