Every tool on Convert PDF is free because one short ad runs before each download or conversion — that is the whole business model: the tools are free, full stop, and the ad is what pays for them. Your browser is currently blocking those ads, so the tools can't run.

Convert PNG to AVIF when you want the absolute smallest web images and can wait for the encode. PNG is the lossless image format with real transparency — razor-sharp for graphics, screenshots and logos, bigger than JPG for photos; AVIF is the AV1-codec image format — the smallest high-quality stills on the modern web, with HDR colour, at the cost of slow encoding. Upload your PNG, hit convert, download the AVIF — free, no sign-up, no watermark.
Documents are unforgiving — a layout that shifts is a document that is wrong — so the PNG to AVIF Converter on Convert PDF uses real conversion engines and treats your files carefully: processed in a one-off temporary folder and deleted the moment your download finishes, because people merge bank statements and contracts with tools like these.

PNG is the lossless image format with real transparency — razor-sharp for graphics, screenshots and logos, bigger than JPG for photos. AVIF is the AV1-codec image format — the smallest high-quality stills on the modern web, with HDR colour, at the cost of slow encoding. The conversion re-writes the image data once, in the AVIF layout, at the original dimensions. File sizes stay in the same ballpark — both formats compress with loss, so the AVIF lands within roughly a third of the PNG's size at these quality settings. People make this exact swap when you want the absolute smallest web images and can wait for the encode.

Why people pick this over other converters
No account, ever. Most big converter sites push sign-ups and paid tiers for basic jobs. Here the tool just works.
No watermarks and no job counters on standard tools — fair-use rate limits keep things fast for everyone — and a generous 200 MB upload limit.
Private by design: your file is processed in a temporary folder and deleted the moment your download finishes. Nothing is stored or shared.
Fast: this page is a fraction of the size of the ad-heavy alternatives, and the same account-free toolbox has 102 other tools when you need them.
FAQ
Will converting PNG to AVIF lose quality?
This is the one-way door: AVIF compression discards some data permanently in exchange for a much smaller file. Our settings are tuned high so the difference is usually invisible — but keep your lossless PNG as the master copy.
When should I convert PNG to AVIF?
Convert when you want the absolute smallest web images and can wait for the encode. If your PNG already opens where you need it, converting buys nothing — this swap earns its keep the moment a device, app or upload form refuses PNG but accepts AVIF.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
