Convert Images in 4 Simple Steps
Quickly transform your images with our streamlined conversion process. Every file is processed through a scalable background queue with real-time status updates — so you can convert hundreds of images at once and watch each one move from In queue to Processing to Ready. No software installation required.
Upload Image Files
Click 'Choose Files' or drag & drop your images into the upload area. Supports multiple files at once.
Select Format & Settings
Choose your target format (WebP, PNG, JPG, etc.) and adjust quality, size, and other conversion options.
Queued & Converted
Click 'Convert All' and each image is queued and processed in the background. Track live status for every file — In queue, Processing, then Finalizing — updated in real time.
Download
As soon as a file is Ready, download it individually or grab everything as a ZIP. Queued processing keeps large batches going even with hundreds of images.
How the Image Converter Works
Drop your images, pick a target format, and convert. Every file is queued and processed in the background with real-time status — In queue, Processing, then Ready — so you can convert hundreds of images at once without the page freezing.
From PNG to AVIF: Compressing High-Quality Web Images
PNG has been the gold standard for web images since the mid-1990s — it's lossless, supports transparency and full color depth, and asks nothing of browsers except basic rendering. But PNG files can be bulky, especially for photographs or complex graphics. AVIF, built on the AV1 video codec by the Alliance for Open Media and released in 2019, was engineered to solve exactly this: deliver the same visual quality as PNG in a fraction of the file size, with added support for modern features like HDR and animation.
Why Convert PNG to AVIF?
Every PNG image you post on the web carries the weight of lossless compression — a noble choice for quality, but often overkill for web delivery where a modern lossy codec can preserve perceived quality while cutting file size by 50% or more. Converting PNG to AVIF keeps transparency and quality intact while dramatically shrinking the payload, which means faster page loads and better Core Web Vitals scores without any visible degradation to most users.
Stepping Into the Modern Web
AVIF adoption is growing rapidly in modern browsers, and it's now the preferred format for performance-conscious web teams building on current infrastructure. If your site targets modern browsers (Chrome, Firefox, Edge, Safari 16+), converting PNG to AVIF is one of the highest-impact optimizations you can make — the file size gains are substantial enough to be measurable in page load time and bandwidth costs.
Why Convert PNG to AVIF Online
Dramatically Smaller Files
AVIF's modern compression typically produces 40-50% smaller files than PNG while maintaining full visual quality.
Better Core Web Vitals
Smaller images mean faster loads and improved Largest Contentful Paint (LCP) scores for SEO and user experience.
Full Color and Transparency
AVIF preserves PNG's transparency and adds support for HDR and wide color gamut for future-ready content.
Instant Browser Conversion
No software needed — convert PNG to AVIF directly in your browser in seconds, with automatic deletion of your files.
PNG vs AVIF: Key Differences
| Feature | PNG | AVIF |
|---|---|---|
| Released | 1996 | 2019 |
| Compression | Lossless only — larger file sizes | Lossy and lossless — typically 40-50% smaller at similar quality |
| Transparency Support | Full alpha-channel transparency | Full alpha-channel transparency |
| Animation Support | Not applicable — static image format | Supported, with efficient encoding |
| Browser/Software Support | Universal across all browsers and operating systems | Modern browsers (Chrome, Firefox, Edge, Safari 16+) |
| Best Use Case | Screenshots, logos, graphics, and anything requiring transparency without compression trade-offs | Modern web delivery where file size and performance matter most |
Where PNG and AVIF Each Make the Most Sense
Office Documents & Screenshots
Screenshots, diagrams, and slide graphics stay pixel-perfect in PNG, making it the safer pick for office work where exact detail matters more than file size.
Email Attachments Needing Exact Clarity
When a screenshot or logo needs to look crisp for every recipient, PNG's lossless compression avoids artifacts a lossy format can introduce.
Optimizing Images for a Web Page or Blog
AVIF's smaller file size directly improves page load speed, making it the default choice when you need to optimize images for a website or blog post.
Ecommerce Product Galleries
Product photo grids load faster in AVIF without sacrificing visible quality, helping conversion-sensitive pages stay quick.
High-Traffic Photo Galleries
Sites serving thousands of product or portfolio images benefit most from AVIF's file-size savings, since the reduction compounds across every image on the page.
