About AVIF to PNG Conversion
Converting AVIF to PNG sits at the intersection of two of the most-searched questions in image workflows: file compatibility and file size. AVIF files behave well in their native environment but cause friction when you need to share, edit, or publish them somewhere that expects PNG. The most common triggers for this conversion are uploading to a platform that rejects AVIF, opening the file in software that does not recognize it, attaching the image to a document workflow, and reducing the file size for faster web delivery. None of those problems require a server upload — the file format is fully described, the math is well-known, and a modern browser has every API needed to do the conversion locally. AVIF squeezes images down with AV1 intra-frame coding, which is brilliant for shipping a page fast but leaves you with a file most desktop software still won't open. Converting to PNG trades that compactness for a lossless, universally editable raster that any tool from MS Paint to Photoshop reads without a plugin. Because PNG stores every pixel and a full 8-bit alpha channel, the transparency and sharp edges baked into your AVIF survive the trip intact.
Why People Convert AVIF to PNG
There is no single reason to convert AVIF to PNG; there are four overlapping ones. Compatibility is the most common: the destination application, website, or printer simply does not accept AVIF. File size is the second: PNG either compresses better (saving bandwidth) or worse (preserving fidelity) than AVIF, and the right choice depends on what you do next with the image. Editing is the third: some editors strip metadata or refuse to open certain AVIF variants, while PNG loads cleanly. And finally there is preservation — converting between lossless formats avoids generation loss when you plan to keep editing the file. FileChange handles all four motivations in the same one-click flow. Most people land here because they downloaded an AVIF from a modern website and their everyday app — Windows Photos on an older build, a printer driver, or a design tool — just shows a blank or an error. PNG is the safe lowest-common-denominator that opens everywhere and keeps transparency, so it's the practical 'make this usable again' target.
How to Convert AVIF to PNG Online
- Open FileChange. Open this AVIF to PNG converter in any modern browser — Chrome, Firefox, Safari, or Edge all work. No installation, no plugin, no account.
- Drop your AVIF file. Drag your AVIF file into the upload area, or click to browse your device. You can also drop multiple files at once for batch conversion.
- Confirm PNG as the target. PNG is pre-selected. Optionally open "Advanced settings" to tune quality, resolution, or other format-specific options.
- Click Convert. Your file is processed locally in your browser. The first run loads the conversion engine; subsequent files convert almost instantly.
- Download your PNG. When the conversion finishes, the PNG file downloads automatically. Nothing was uploaded, nothing is stored, nothing leaves your machine.
How the AVIF → PNG Conversion Works
FileChange converts AVIF to PNG using the browser Canvas API to redraw your image into the target encoder. The flow is straightforward: your AVIF file is read from disk via the File API, decoded into an intermediate representation, transformed into the PNG target, and offered back as a download. Every step runs on your own device — there is no server in the loop, no queue, and no third-party storage. The same approach is used by professional desktop converters; running it in the browser just removes the install step.
Top Use Cases for AVIF to PNG
- Opening an AVIF you saved from a website inside Photoshop or GIMP, neither of which reliably decodes AVIF, so you re-export as PNG first to start editing.
- Pasting an image with a transparent background into a PowerPoint slide or Figma frame, where PNG's alpha is honored but a raw AVIF often won't import at all.
- Open AVIF files in apps and platforms that only accept PNG
- Reduce file size for email, messaging, and web delivery by switching from next-generation AV1-based image format to lossless image format with transparency
- Batch convert many AVIF files at once without uploading them anywhere
- Keep sensitive AVIF content private — the conversion happens entirely on your device
- Avoid signup walls, watermarks, and trial limits on competing online converters
- Prepare AVIF images for PNG-only platforms (some CMSs, email clients, design tools)
About the AVIF Format
AVIF is the newest major image format, based on the AV1 video codec developed by the Alliance for Open Media (AOMedia). Released in 2019, AVIF offers superior compression compared to both JPG and WebP, producing files that are 50% smaller than JPG and 20% smaller than WebP at equivalent visual quality. The format supports high dynamic range (HDR), wide color gamut, film grain synthesis, and both lossy and lossless compression. AVIF here is the compact, web-optimized source whose AV1 efficiency is exactly why it's awkward to edit — the same compression that saves bandwidth is what older apps can't decode.
AVIF was released in 2019 and now supported across every modern browser, offering significantly better compression than JPEG.
About the PNG Format
PNG is a lossless raster image format created in 1996 as a patent-free replacement for GIF. Every pixel in a PNG file is stored exactly as saved, with no compression artifacts or quality degradation. PNG supports full alpha channel transparency, making it the standard format for logos, icons, screenshots, UI elements, and any image that requires crisp edges or transparent backgrounds. PNG is the destination chosen for reach, not for size: it re-encodes the decoded pixels losslessly and keeps the alpha channel, so the image becomes editable and broadly compatible at the cost of a much bigger file.
PNG was created in 1996 as a patent-free replacement for GIF, then quickly adopted as the web standard for graphics and screenshots.

Quality tips for AVIF → PNG
When converting AVIF to PNG, the single most impactful setting is the output quality slider. Above 85% you cannot perceive any compression artifacts in normal viewing; below 60% the image starts to feel visibly degraded. FileChange defaults to 92% quality, which is visually lossless for nearly all photographs and screenshots. If PNG is a lossless format (PNG, BMP, TIFF), the quality slider is irrelevant — every pixel is preserved exactly. For AVIF to PNG conversions involving a lossy target, you can also resize down to the actual display size to drop file size further without any visible loss. FileChange exposes both controls under "Advanced settings" before you hit Convert. PNG can't undo the lossy compression AVIF already applied, so any AV1 artifacts in flat skies or gradients are carried over and frozen in place; what you do gain is that no new loss is added and the alpha channel is preserved exactly.
Troubleshooting
The PNG comes out several times larger than the AVIF you started with, which surprises people expecting a 'converted copy' to stay small.
That's inherent — photographic data doesn't compress well losslessly. If small size matters more than universal editability, convert to WebP instead, which keeps the alpha and stays far closer to the AVIF's footprint.
The conversion is slower than expected
Heavy formats (video, large PDFs, big audio files) run entirely on your CPU. The first conversion in a session loads the WASM engine (about 30 MB for FFmpeg, 2 MB for PDF.js) — subsequent conversions reuse the loaded engine and run much faster. Close other heavy tabs to free memory.
The output PNG looks different from my AVIF
Format conversions are not always pixel-identical. Color spaces, font substitutions, and metadata can shift. For best fidelity, use the highest-quality original you have, and pick lossless target formats (PNG, FLAC, WAV) when fidelity matters more than file size.
The browser ran out of memory
Very large files (multi-GB videos, 1000-page PDFs) can exhaust a browser's memory. Split the file into smaller chunks, close other tabs, or use a desktop converter for files over 2 GB.
The colors look washed out or off
Color profile data sometimes does not survive a conversion. Most browsers assume sRGB; if your source has a wide gamut profile (Display P3, Adobe RGB), the output may render flatter. Open the converted file in software that respects embedded color profiles for accurate color.
Frequently Asked Questions about AVIF to PNG
Will converting AVIF to PNG make the image look sharper or higher quality?
No. PNG is lossless, so it perfectly preserves whatever the AVIF already contains, but it can't recover detail that AVIF's lossy compression discarded. The picture looks the same — it just becomes editable and universally openable.
Does the transparency in my AVIF survive the conversion to PNG?
Yes. PNG has a full 8-bit alpha channel, so transparent and semi-transparent areas from the AVIF are carried over exactly, with no hard-edge fringing.
Why is the PNG so much bigger than the original AVIF?
AVIF uses modern AV1 compression while PNG stores pixels losslessly, so a compact AVIF photo typically expands to several times its size as PNG. That size is the price of lossless, broadly compatible storage.
Is FileChange's AVIF to PNG converter really free?
Yes, completely free. There is no signup, no free trial that runs out, no credit card, and no watermark on the output. Convert as many AVIF files to PNG as you need, as often as you want.
Is my AVIF file uploaded to a server when I convert to PNG?
No. The conversion runs entirely inside your browser using the browser Canvas API to redraw your image into the target encoder. Your file is read locally, processed on your CPU, and the resulting PNG is generated on your device. Nothing is transmitted, stored, or logged anywhere.
How long does AVIF to PNG conversion take?
Image conversion is nearly instant — typically under a second. Very large images (50+ megapixels) take a few seconds longer because of the canvas redraw.
Is there a file size limit when converting AVIF to PNG?
There is no hard cap — your device's available memory is the real ceiling. In practice, most AVIF files up to a few hundred megabytes convert without issues. Very large files (multi-GB videos, thousand-page PDFs) may slow down or fail on low-memory devices.
Can I batch-convert multiple AVIF files to PNG at once?
Yes. Drop as many AVIF files as you like in a single batch and FileChange converts them all in one click. Each file is processed independently and then offered as a download.
