Drag on the preview to move the empty middle, and drag the small dots to make it wider or taller.
Download

Everything is drawn in your browser. Nothing is uploaded.
Questions
How do I put the lines over my thumbnail?
Pick My picture as the background and drop your thumbnail in, or download the lines see-through and stack them in your editor.
How do I get the exact same lines again?
The lines come from the seed. The same seed and settings always draw the same lines, and Copy link keeps them all. New lines picks a new seed.
Is my picture uploaded?
No. Your picture stays in your browser and is only used to draw the PNG on your device. It is not part of the link either.
Does the SVG include my picture?
No. The SVG has the lines (and a color background if you chose one), so it stays small and sharp. The PNG includes your picture.
What size works for Roblox thumbnails?
Thumbnail (1920 × 1080) is the size Roblox uses for game thumbnails. For UI images, Square (1024 × 1024) is plenty.
