Pick from three ready-made Twitter / X presets: Post image (1200×675) for feed posts that display without cropping, Profile photo (400×400) for your circular avatar, or Cover photo (1500×500) for your header with safe-zone centering.
Export as PNG to get the sharpest result after Twitter's recompression, then upload directly to Twitter / X — no quality loss, no unexpected feed crops.
Journalists, founders, creators, and community managers resize images daily on Twitter / X to avoid the feed's automatic 16:9 crop and maintain pixel-sharp quality after Twitter's recompression pass.
Founders posting launch screenshots or dashboard previews use the 1200×675 post image preset to guarantee the full UI is visible in the feed without Twitter auto-cropping the bottom. A PNG export preserves text legibility even after Twitter's recompression.
Reporters sharing infographics or data visualizations resize to 1200×675 so the chart's x-axis labels are never cut off in the timeline view. The exact 16:9 ratio means editors and followers see the full story without clicking through.
Social media managers use the 400×400 profile photo preset to pre-crop logos or headshots so the subject stays centered inside Twitter's circular display mask. Uploading the correct square dimensions avoids the awkward auto-crop Twitter applies to non-square images.
Influencers and newsletter writers updating their cover photo use the 1500×500 preset and keep key text within the center 80% of the canvas, since Twitter crops the left and right edges on mobile screens. The tool's live preview makes safe-zone placement obvious before export.
Engineers sharing terminal output or code snippets resize to 1200×675 so the full width of long lines is visible in the feed rather than hidden behind a 'show more' tap. PNG export keeps monospaced font rendering crisp after Twitter's image pipeline.
Marketing teams adapting banner ads or print assets for Twitter use the post image preset to convert widescreen or portrait creatives into the exact 1200×675 frame Twitter expects. This prevents the platform from making unpredictable crops that cut off taglines or calls to action.
Twitter/X displays post images at a 16:9 ratio. The recommended size is 1200×675 pixels. Images smaller than this will be upscaled and may appear blurry.
Twitter/X displays profile pictures as circles. Upload a square image at 400×400 pixels minimum. The platform crops it to a circle automatically.
The Twitter/X header photo is displayed at 1500×500 pixels (3:1 ratio). Note that the bottom and sides may be cropped on some screen sizes, so keep important content centered.
Yes, Twitter recompresses uploaded images. Uploading at exactly 1200×675 pixels in PNG or JPG at high quality will give the best result after compression.
