Why Convert PNG to AVIF?
Converting from PNG Image to AVIF Image is useful when you need best-in-class compression (smaller than webp and jpeg). PNG Image has limitations: larger file sizes than jpeg for photographs. AVIF Image addresses this by offering best-in-class compression (smaller than webp and jpeg) and royalty-free and open-source. AVIF (AV1 Image File Format) is a next-generation image format based on the royalty-free AV1 video codec.
Note: This conversion goes from a lossless format (PNG Image) to a lossy format (AVIF Image). Some data will be permanently removed during compression, though the result should be visually or audibly indistinguishable at high quality settings. Consider keeping your original PNG file as a master copy.
PNG vs AVIF — Technical Comparison

About PNG Image
PNG (Portable Network Graphics) is a lossless raster image format that supports transparency. Developed as an open-source alternative to GIF, PNG delivers pixel-perfect image quality without compression artifacts, making it the top choice for logos, icons, screenshots, and graphics with text.
Strengths
- ✓ Lossless compression preserves perfect quality
- ✓ Full alpha transparency support
- ✓ Great for text, logos, and sharp graphics
- ✓ Open standard with no licensing fees
Limitations
- • Larger file sizes than JPEG for photographs
- • No native animation support (use APNG)
- • Not ideal for print workflows (CMYK not supported)
Developed by PNG Development Group (1996)
About AVIF Image
AVIF (AV1 Image File Format) is a next-generation image format based on the royalty-free AV1 video codec. AVIF offers the best compression efficiency of any current image format — up to 50% smaller than WebP and dramatically smaller than JPEG — while supporting HDR, wide color gamut, and transparency.
Strengths
- ✓ Best-in-class compression (smaller than WebP and JPEG)
- ✓ Royalty-free and open-source
- ✓ HDR and wide color gamut support
- ✓ Both lossy and lossless compression
Limitations
- • Slower encoding than JPEG or WebP
- • Growing but not yet universal browser support
- • Complex format requires more CPU to decode
- • Relatively new with limited editor support
