Frequently Asked Questions
Is Zap My Picks safe to use? Are my images uploaded? +

What image formats are supported? +
You can upload JPG, PNG, GIF, WebP, AVIF, and SVG files. You can convert images to JPG, PNG, WebP, AVIF, or GIF formats.
What does "Optimize Size" do? +
The "Optimize Size" option (including the "Quick Optimize" button) attempts to reduce the file size of your images with minimal loss of visual quality.
It may automatically convert your image to a more efficient format like WebP or AVIF (if supported by your browser and beneficial for size) and applies smart compression settings. It only keeps the optimized version if it's smaller than the original.
Which format should I choose for the web? +
Generally, WebP offers excellent compression and quality and is widely supported.
AVIF is even newer and often provides better compression than WebP, but browser support is still growing.
JPG is best for photographs but doesn't support transparency.
PNG is great for graphics with transparency but can result in larger files.
GIF is suitable for simple animations.
