Frequently Asked Questions
How do I convert PNG to AVIF online?
Drag and drop your .png file (or click to browse). The converter decodes the PNG losslessly and re-encodes as AVIF — lossy by default (quality 80) or lossless for graphics needing pixel-exact preservation. Download the .avif result. Conversion runs on Toolsana's server: your file is uploaded, processed in memory and not saved. AVIF encoding is CPU-intensive — typical conversion takes 1-5 seconds per image.
Will converting PNG to AVIF reduce image quality?
Depends on mode. Lossy AVIF (default) re-encodes the pixels with some loss — file size drops by 80-95% but visual quality is nearly indistinguishable at quality 75+. Lossless AVIF preserves every pixel exactly, with file size typically 50-70% smaller than the source PNG. For photographs, use lossy AVIF (much smaller, imperceptibly different). For graphics/screenshots/logos needing exact preservation, use lossless AVIF or stick with PNG.
Are my images uploaded to a server?
Yes. Your image is sent over an encrypted (TLS) connection to Toolsana's server, processed in memory and returned to your browser. The image is not saved or shared once processing finishes. Because the work happens on the server and not in your browser, don't upload images you aren't willing to send off your device.
Does the conversion preserve transparency?
Yes — both PNG and AVIF support alpha channels, so transparency survives the conversion intact. This is one of AVIF's advantages over JPEG (which has no alpha). Use this conversion for product photos, logos, and graphics where transparency matters AND you want significant file size savings vs PNG. EXIF metadata is typically stripped during conversion (privacy benefit — removes GPS/camera data; loses orientation tags if any).
What is AVIF and when should I use it?
AVIF (AV1 Image File Format) is a modern image format published in 2019, based on the AV1 video codec. ~50% smaller than JPEG at equivalent perceived quality, supports alpha transparency, HDR colour, animation. Decoding supported in Chrome 85+, Firefox 93+, Safari 16+, Edge 121+ — ~95% browser coverage in 2026. Use AVIF for web hero images, product photos, and any image where file size matters. For broader compatibility, use [PNG to WebP](/tools/png-to-webp/) instead.
Why is AVIF so much smaller than PNG?
Because PNG uses lossless compression and AVIF (in default lossy mode) uses lossy compression based on modern AV1 video coding. PNG must preserve every pixel exactly, which is verbose for photographic content; AVIF discards visual information that's hard for humans to notice, achieving 80-95% smaller files at the same perceived quality. For graphics and screenshots where every pixel matters, the gap narrows (still 50-70% smaller in lossless AVIF mode).
Can I control the AVIF output quality?
Yes. In lossy mode the quality slider runs from 10 to 100 (default 80); around 75-80 is the visually-lossless sweet spot for AVIF (roughly equivalent to JPEG quality 85). Quality 60 still looks excellent in most cases with significantly smaller files. The encoding effort slider (0-9) trades encoding time for a smaller file. For lossless mode, choose Lossless (typically 5-10x larger than lossy 75 but pixel-exact). For aggressive web optimisation, quality 50-60 is the practical floor for AVIF; below that, WebP or JPEG at the same quality might look better.
When should I convert PNG to AVIF?
Three common cases. (1) Web performance — replacing large PNG screenshots or hero images with AVIF can shrink file sizes 80-95% with no visible quality loss, dramatically improving LCP. (2) Storage cost reduction for large image archives. (3) Bandwidth-constrained delivery (mobile, costly CDN egress). Implement with `<picture>` element fallbacks: `<picture><source srcset='image.avif' type='image/avif'/><source srcset='image.webp' type='image/webp'/><img src='image.png'/></picture>` covers all browsers.
