PNG to AVIF Features
• Modern compression algorithm for better efficiency
• Preserves PNG transparency
• Small file size saves storage space
• Quality control for optimized file size
PNG files carry every pixel faithfully, but their file sizes can balloon — especially for screenshots, icons, and graphics with flat color. Image Machine converts PNG to AVIF in your browser, slashing file size while preserving the alpha transparency that PNG is known for. No upload required; your files stay local.

Frequently Asked Questions
Does AVIF support a transparent background like PNG?
Yes — AVIF fully supports alpha transparency. Unlike JPG, which forces a solid background, AVIF preserves transparent areas just as PNG does. This makes PNG-to-AVIF a practical swap for web assets like logos, icons, and UI elements with cutout backgrounds.
How much smaller is AVIF compared to PNG?
Typically 50–70% smaller for photographic content and 30–50% smaller for graphics and flat-color illustrations. The exact savings depend on the image's complexity, but for most web assets the difference is dramatic — especially for large PNG screenshots or hero images.
Should I use AVIF instead of PNG for website icons and logos?
If your visitors are on modern browsers (Chrome, Firefox, Edge, Safari 16.4+), AVIF is an excellent replacement for PNG icons and logos — you keep full transparency and cut file size significantly. For broader compatibility, serve AVIF with a PNG fallback using the HTML picture element.
Is converting PNG to AVIF a lossless process?
AVIF supports both lossy and lossless compression modes. Most browser-based converters default to high-quality lossy encoding, which looks visually identical to the source but produces a smaller file. True lossless AVIF mode produces pixel-exact output at a somewhat larger file size.
My PNG files are too large for my website — will converting to AVIF help?
Almost certainly yes. AVIF's AV1-based compression is far more efficient than PNG's DEFLATE algorithm. Images that were previously too heavy to serve quickly — detailed screenshots, product graphics, or app UI assets — routinely shrink 50% or more after conversion to AVIF.
