Why Use PDFBro to Resize Images
Frequently Asked Questions
What is the Twitter/X header photo size?
1500x500 pixels is the recommended upload size. This 3:1 aspect ratio works across all Twitter interfaces. The header is responsive — different parts are visible on mobile vs desktop. Place important content in the center horizontal band (roughly 1500x300) that's visible everywhere.
Why does my Twitter header look different on mobile vs desktop?
Twitter's responsive design shows different header crops on different devices. Mobile shows a taller center crop. Desktop shows more of the sides. Place critical information (logos, text, calls-to-action) in the center 60% of the 1500x500 image to ensure visibility on all devices.
What file format and size limit for Twitter headers?
Twitter accepts JPEG and PNG up to 5 MB. At 1500x500 resolution, a JPEG at 85% quality stays well under 1 MB while looking excellent. PDFBro resizes your image to the exact dimensions and you can choose the output format that suits your needs.
Can I use the same banner image for Twitter and Facebook?
No — Facebook covers are 851x315 (2.7:1) and Twitter headers are 1500x500 (3:1). They're different aspect ratios. Resize your banner separately for each platform using PDFBro's dedicated tools to avoid awkward cropping or stretching.
