FAQ
Why does my header look cropped on mobile?
X renders headers differently across devices and layouts, so edges can be cropped.
Quick tip: Keep logos/text closer to the center and avoid corner placement.
Common mistake: Placing important elements at the far left/right edges—those areas often get cut.
Crop or Pad for headers?
Pad is usually safer because it preserves the full design and reduces edge loss.
Quick tip: Treat side edges as flexible space and keep critical info centered.
Common mistake: Designing a “full-width” text banner—small crops break the message.
PNG or JPG for logos/text?
Use PNG for sharp logos/text and JPG for photo banners.
Quick tip: If you use JPG, increase contrast and export at higher quality.
Common mistake: Using low-quality JPG for logos—edges get fuzzy and artifacted.
Do you upload my images?
No. Processing happens locally in your browser. Your files are not uploaded.
What size should I use?
Use 1500x500 (3:1).
Which export format should I use?
JPG for photos, PNG for text/logos or transparency, WebP for smaller files (if supported).
Crop vs Pad — what is the difference?
Crop fills the target size (may cut edges). Pad fits the whole image and adds background/space.
How do I protect text and logos?
Keep important content centered and avoid placing critical text at the edges.
Can I batch resize?
Yes. Use the Batch Resizer to apply the same size to many images.
