How to use the avif to png converter
- 1Drop your AVIF files onto the box above, or click to browse for them.
- 2Adjust the quality slider if you want a smaller file or a sharper result.
- 3Press Convert and wait while your browser re-encodes each image.
- 4Download the finished PNG files.
Why convert AVIF to PNG?
A modern format derived from the AV1 video codec, delivering the smallest files of any widely-supported image format. That is exactly what you want when the file is being archived or edited, and an obstacle when it has to be emailed, uploaded or served on a web page. PNG solves the second problem.
A lossless raster format built for screenshots, logos and any artwork with hard edges or transparency. For a AVIF source specifically, the payoff is pixels survive the round trip untouched — no generation loss, ever — and alongside that, full 8-bit alpha channel, so transparency stays clean against any background and universally supported by every browser, OS, email client and CMS since the late 1990s.
The cost of the switch is worth stating plainly before you make it: file sizes are typically 3-10x larger than JPEG for photographs and there is no quality dial to trade size against fidelity. Weigh that against what AVIF was giving you, which was roughly 50% smaller than JPEG and 20-30% smaller than WebP at matched quality.
Where AVIF files usually come from
Most people arrive at this page holding one of three things: images saved from a performance-focused site that serves AVIF to capable browsers, exports from a modern static site build pipeline, or photos returned by a CDN doing automatic format negotiation.
Knowing which one you have matters, because it changes the right settings. Photographic content tolerates aggressive compression well — the eye is forgiving about noise in a sky or a skin tone. Screenshots, charts and line art do not: they contain hard edges and small text, which is precisely what lossy compression handles worst. If your AVIF is the second kind, push the quality slider higher than feels necessary.
AVIF originated in performance-focused websites and modern CDNs, and that lineage explains most of its behaviour: a modern format derived from the AV1 video codec, delivering the smallest files of any widely-supported image format.
What happens to quality when you convert AVIF to PNG
PNG is lossless, so nothing further is discarded here — but it also cannot restore what AVIF already threw away. Whatever compression artefacts are baked into your source will be preserved with perfect fidelity, artefacts included. Converting to PNG buys you compatibility and editing headroom, not repaired quality.
This is the single most common misunderstanding about the conversion. If your AVIF looks blocky, converting it to PNG will produce a larger file that looks exactly as blocky.
Transparency survives intact. Both AVIF and PNG carry an alpha channel, so cut-out logos and images with soft, feathered edges convert without picking up a background.
If your AVIF is animated, only the first frame is converted — PNG here is a still-image output. Use a video tool if you need the whole sequence.
How much smaller (or larger) will the file be?
Expect the file to grow, often by a factor of three to ten. This surprises people, but it follows from the maths: PNG must store every pixel faithfully, including the compression artefacts inherited from the AVIF, and artefacts are noisy data that compresses badly.
There is no quality dial to turn, because PNG is lossless — the size you get is the size the image compresses to. The one lever you do have is the max-width setting: halving the width quarters the pixel count, and file size falls roughly in step.
When converting AVIF to PNG is the wrong move
This conversion is not always the right answer, and it is cheaper to know that now than after you have replaced your originals. Skip it if file size is your actual constraint — you will end up with something several times larger and no better looking and the animation matters, since only the first frame comes across.
A reasonable default: keep your AVIF originals in a folder you do not touch, and treat the PNG output as a derived, disposable copy for whatever you are publishing or sending. That way a bad quality setting costs you a re-export rather than the image.
Your AVIF files never leave your device
Server-side conversion is the industry default, which means the normal price of a free converter is a copy of your image living somewhere you cannot see.
This converter does not work that way. Your AVIF is decoded by the browser's own image pipeline, drawn into an off-screen canvas, and re-encoded as PNG — all inside this tab, on your processor. There is no upload progress bar because there is no upload, no queue because there is no server, and nothing to delete afterwards.
Nothing here is taken on trust — disconnect from the network after the page loads and the tool still converts, which it could not do if a server were involved. A practical side effect is that speed depends on your own hardware rather than on someone else's server load, and there is no file size cap beyond your available memory.
Frequently asked questions
Is this AVIF to PNG converter really free?
Yes — no account, no watermark, no daily cap. The conversion runs on your own processor, so it costs nothing to serve and there is nothing to meter.
Are my AVIF files uploaded anywhere?
No. The file is read locally, decoded into a canvas and re-encoded to PNG entirely within this browser tab. No image data crosses the network at any point.
Can I convert several AVIF files at once?
Yes. Drop in as many as you like and each is converted with the same settings, one at a time so a large batch does not exhaust your memory.
Will converting to PNG improve my image quality?
No. PNG preserves whatever it is given perfectly, but cannot reconstruct detail AVIF already discarded. Expect an identical-looking image in a larger file.
What happens to my animated AVIF?
Only the first frame is converted, because the output here is a still image. To keep the motion you need a video or animation tool rather than an image converter.
Why can I not save back to AVIF?
Browsers can decode AVIF but cannot yet encode it through the canvas API. Reading AVIF works everywhere modern; writing it needs a WebAssembly encoder, which is on the roadmap here.
Does the converter change my image dimensions?
Not unless you ask. Output keeps the exact pixel dimensions of the source; the max-width box is empty by default and only resizes when you fill it in.
