Convert AVIF images to PNG format with transparency support and lossless output. Compatible with all devices. No software installation needed, direct browser conversion, supports batch processing, completely free.
Supports .avif format, max 50MB per file, up to 20 files at once
PNG format fully supports Alpha channel transparency. Converted images maintain original transparent backgrounds and semi-transparent effects, ideal for design editing workflows.
PNG uses lossless compression algorithm. No image quality loss during conversion process, pixel-level accurate reproduction of every detail from original AVIF images.
Support uploading up to 20 AVIF files at once for batch conversion, greatly improving efficiency and saving repetitive operation time.
Completely free online tool, no registration required, no usage limits, no hidden fees, available anytime.
All conversion operations complete locally in your browser, files never uploaded to any server, protecting your data privacy.
Supports Windows, Mac, Linux and mobile browsers. Use anytime anywhere. Converted PNG files can be opened on any device and software.
Click upload area to select AVIF image files, or drag and drop directly into the designated area. Supports multi-select, up to 20 files at once, max 50MB per file.
After upload, automatically displays thumbnails and file info (name, size). You can verify each one individually. Click delete button to remove incorrectly selected files.
Once files are confirmed correct, click "Convert to PNG" button. Since PNG is lossless format, no quality parameter settings needed, tool performs optimal conversion automatically.
Progress bar shows real-time conversion status. Speed depends on file count and size, typically completes within seconds to tens of seconds.
After completion, result statistics are displayed. Click each file's download link individually, or use batch download button to get all PNG files at once.
AVIF (AV1 Image File Format) is a modern image encoding format developed by Alliance for Open Media (AOMedia), based on AV1 video codec technology. It uses advanced compression algorithms, achieving approximately 50% smaller file sizes than JPEG and 20% smaller than WebP at equivalent quality levels, making it one of the most efficient mainstream image formats today. However, as a relatively newer format, AVIF may have compatibility issues on older software and devices, especially in web applications and design workflows requiring broad support.
PNG (Portable Network Graphics) is a raster image format that employs lossless data compression. Its most notable feature is support for 24-bit true color and complete Alpha channel transparency. Developed by W3C (World Wide Web Consortium) to replace GIF format, PNG has become one of the preferred formats in web design, icon creation, UI interfaces, screenshot saving, and other fields due to its lossless nature and extensive software support.
| Feature | AVIF | PNG |
|---|---|---|
| Compression Type | Lossy + Lossless | Lossless Only |
| Transparency | Supported | Full Alpha Channel |
| Compression Efficiency | Very High | Moderate |
| Compatibility | Modern Browsers Only | Universal Platform |
| Best Use Case | Web Display, Storage Optimization | Design Editing, Transparent Assets |
Despite AVIF's excellent compression performance, there are many practical limitations: Many older browsers, image editing software, and printing services don't support AVIF; PNG's lossless characteristics and transparency channel support make it the standard format for design and print industries; When you need secondary editing in professional software like Photoshop or Illustrator, PNG is more reliable; Additionally, some CMS systems and e-commerce platforms only accept PNG format uploads.
When designers need to import AVIF images from asset libraries into Sketch, Figma, Adobe XD, or other design tools, PNG is the most compatible format. Especially for icons and button elements with transparent backgrounds, PNG's Alpha channel support is essential.
Social media platforms, forums, blog systems often don't support or limit AVIF uploads. Converting to PNG ensures images display properly on any platform, avoiding loading failures or format errors.
When inserting images into Word documents, PDF reports, PPT presentations, PNG's compatibility and clarity advantages are obvious. The print industry generally requires lossless format source files to ensure output quality.
When web developers need fallback image resources for different browsers, PNG serves as the safest fallback format. Combined with CSS image-set() property or <picture> tags for progressive enhancement loading strategy.
When photographers use Lightroom, Capture One, or other professional software for color grading and retouching, intermediate files are typically saved as TIFF or PNG to avoid quality degradation from repeated lossy compression. AVIF to PNG can be the first step entering the editing workflow.
