Frequently Asked Questions
What sizes are available as presets?
PureKit includes presets for common sizes: 150×150 (avatar), 300×250 (medium rectangle ad), 728×90 (leaderboard ad), 1200×630 (OG image), 1200×675 (Twitter card), 1080×1080 (Instagram), 1920×1080 (HD), 375×667 (mobile), and 32×32 (favicon).
Is the image generated on the server?
No. The image is generated entirely in your browser using the HTML Canvas API. Nothing is uploaded to any server, making it fast and private.
What is the maximum image size?
You can generate images up to 4096×4096 pixels. Larger sizes depend on your browser and device memory.
What is the difference between PNG, WebP, and SVG?
PNG is widely supported and lossless. WebP offers smaller file sizes with good quality. SVG is vector-based, scales to any size without quality loss, and is ideal for web use.
