Frequently Asked Questions
What thumbnail sizes are supported?▼
YouTube (1280×720), TikTok (1080×1920), Instagram (1080×1080), Twitter/X (1200×675), and a Custom size where you enter any dimensions up to 4096×4096. The export always downloads at full resolution.
Can I add multiple text layers?▼
Yes. You can add as many text layers as you like, each with independent position, font size, font weight, colour, shadow, and outline settings. Use the up/down arrows to reorder layers and the trash icon to delete them.
Can I use my own image as the background?▼
Absolutely. Switch the background to 'Image', upload any JPEG, PNG, or WebP file, and choose between Cover (fills the canvas, may crop), Contain (fits inside, adds black bars), or Stretch (fills exactly). Add a dark overlay to make text more readable over busy photos.
Are my images uploaded anywhere?▼
No. All processing — background rendering, text compositing, and PNG export — happens entirely in your browser using the Canvas 2D API. Nothing is sent to a server.
What format does the thumbnail download as?▼
Always PNG for lossless quality. For YouTube thumbnails the standard recommends JPG at 2MB max, but PNG is fine for upload and preserves perfect quality.
