SVG vs PNG for Twitter/X Headers
X profile headers require raster upload — design in vector for precision, then export PNG at the platform's exact recommended size.
Platform Requirements for Header Images
X (formerly Twitter) profile headers accept JPEG, PNG, or GIF uploads at a specific recommended size (historically 1500x500px, though the platform has adjusted specs over time) — SVG isn't an accepted format, and headers get cropped differently across desktop and mobile views, requiring a designed 'safe zone' for critical content.
- Header images require raster upload — check current platform specs
- Desktop and mobile crop the header differently — design a safe zone
- Text and logos should sit within the center-safe area of the canvas
Vector-First Design Workflow
Design the header as SVG with guide layers marking the safe zone for both desktop and mobile crop views, verify text and logo placement stays within that zone, then export a PNG at the platform's exact current recommended dimensions for a sharp, properly-cropped result across all viewing contexts.
- Guide layers in the SVG source mark the cross-device safe zone
- Verify critical content survives both desktop and mobile cropping
- Export final PNG at the platform's current recommended pixel size
Frequently Asked Questions
Why does my header image get cropped differently on mobile?
X displays and crops the header banner differently between desktop and mobile app views — always keep critical text and logo elements within the safe center zone rather than near the edges to avoid mobile cropping issues.
How often do social platforms change their image dimension specs?
Fairly regularly — always verify current dimensions on the platform's official help documentation before finalizing an export, since specs from even a year ago may no longer be accurate.
