AVIF → PNG

Learn about the formats: What is PNG? What is AVIF?

Convert AVIF images to PNG format for wider compatibility while preserving transparency and visual quality. Ideal for users needing a universally supported image format.

AVIF (AV1 Image File Format) is a modern image format offering superior compression and advanced features like HDR and wide color gamut, often resulting in smaller file sizes. PNG (Portable Network Graphics) is a well-established, lossless format widely supported across devices and browsers, known for its excellent handling of transparency and sharp graphics. Converting AVIF to PNG primarily addresses compatibility issues, allowing AVIF images to be viewed and used in environments where the newer format is not yet supported. During this conversion, the AVIF's visual data, including transparency, is re-encoded into the PNG lossless structure.

Converting AVIF to PNG is a lossless re-encoding of the visual data. While the PNG will preserve the current quality of the AVIF, it's important to note that if the source AVIF was already lossily compressed, this conversion won't restore any previously lost detail.

Tips

Expect larger file sizes for the resulting PNGs compared to the original AVIFs due to PNG's lossless nature.
Verify transparency is correctly preserved, especially if the AVIF had complex alpha channels.
Consider optimizing the PNG output (e.g., using PNG optimizers) if file size is a critical concern *after* conversion.
Use this conversion for specific compatibility needs, not as a general image optimization strategy.

Common use cases

Legacy Software Compatibility: Displaying AVIF images in older photo editors, graphic design tools, or content management systems that lack AVIF support.
Email Attachments: Ensuring image visibility for recipients who might use email clients or viewing software that doesn't natively open AVIF files.
Specific Platform Requirements: Uploading images to certain web platforms or services that only accept widely supported formats like PNG.
Print Preparation: Converting AVIFs for printing services that typically require lossless formats like PNG or TIFF.

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

🎵

Common extensions: MP3, WAV, FLAC, OGG, AAC, M4A, OPUS

Advantages

+ FLAC and WAV preserve full quality for editing
+ MP3 and AAC are universally compatible
+ OPUS delivers great quality at low bitrates

Disadvantages

− Uncompressed WAV files are very large
− Lossy formats cannot be restored to original quality
− DRM-protected files may not convert

Frequently asked questions

No, the conversion to PNG is lossless. It will preserve the visual quality of your AVIF image as it is, but it won't restore any quality lost if the original AVIF was already lossily compressed.

Yes, generally. AVIF uses more efficient compression, so converting to a lossless PNG will typically result in a larger file size.

Yes, PNG fully supports alpha channel transparency, so any transparency in your AVIF image will be accurately preserved in the converted PNG.

While AVIF supports HDR, PNG does not. The conversion process will tone-map HDR content to a standard dynamic range (SDR), which might alter the visual appearance of highlights and shadows.
