About
Which image format is best for Instagram?
Instagram works best with JPG: it accepts PNG too, but turns every photo into JPG when you post it. Images saved from websites are often WebP and screenshots are PNG, which some apps and older phones can't open or upload. Converting them to JPG first gives you a file that works everywhere, and lets you choose the quality yourself.
Keep quality around 85–92%
Higher quality barely looks different but makes files much bigger, and Instagram compresses them again anyway.
Transparent images
JPG can't be transparent, so transparent areas become white or black. Choose the colour that suits your image.

No. The conversion happens in your browser, on your device. Nothing is sent to or stored on our servers.
