About This Tool
PNG files can be surprisingly large, especially for photos or
detailed graphics — and AVIF often shrinks them even further than
WebP can, while still supporting full transparency just like PNG
does. This tool converts your PNG images to AVIF entirely inside
your browser: drop them in and conversion starts immediately, with a
quality slider so you can control the size-versus-sharpness
trade-off yourself.
Key Features
Instant Conversion
No upload step and no button to click — conversion starts the
moment you add an image.
Private & Secure
Your files never leave your device — nothing is ever uploaded to a server.
Batch Processing
Convert a handful of images or hundreds at once — there’s no batch limit.
Transparency Preserved
AVIF supports full alpha transparency, so logos, icons, and cutouts convert cleanly with no background added.
Works Everywhere
Compatible with desktop, tablet, and mobile browsers — no app to install.
Completely Free
No subscriptions, registrations, sign-ups, or hidden limits.
How It Works
Add Your PNG Images
Drag and drop them in, or click to browse — one image or many at once.
Conversion Starts Automatically
No button to press — each image converts to AVIF the moment it’s added.
Fine-Tune If You Want
Drag the quality slider and every image updates live with a fresh preview and new file size.
Download
Save images individually, or grab everything at once as a ZIP.

Frequently Asked Questions
Is this tool free to use?
Yes, completely free, with no sign-up and no limit on how many images you convert.
Are my images uploaded to a server?
No. Every image is converted locally in your own browser and never leaves your device.
Will my PNG’s transparency be kept?
Yes — AVIF supports full alpha transparency just like PNG, so
logos, icons, and cutout images convert without any background
being added.
Will AVIF images work on my website?
AVIF is supported in all current major browsers (Chrome,
Firefox, Safari, Edge). If you need a fallback for very old
browsers, keep the original PNG alongside the AVIF version.
Should I use AVIF or WebP for my PNGs?
AVIF typically produces smaller files than WebP at the same
visual quality, but WebP has slightly broader long-standing
support. If maximum file size savings matter most, choose AVIF;
if you want the safest, most widely tested option, choose WebP.
Can I convert multiple PNGs at once?
Yes — drop in as many as you like and each one converts automatically, with no batch limit.
