What Is PNG?

PNG (Portable Network Graphics) is a lossless image format created in 1995 as a royalty-free replacement for GIF. Its defining feature is lossless compression — every pixel is stored and reproduced exactly, with no quality degradation regardless of how many times the file is saved or re-encoded. PNG also supports full 32-bit RGBA transparency (alpha channel), making it the standard format for UI assets, logos, icons, and any image where a transparent background is required.

PNG is universally supported across every browser, operating system, image editor, CMS, and design tool. Figma, Sketch, Adobe Photoshop, Illustrator, Canva, WordPress, Shopify, and every other platform you are likely to work with natively accepts PNG. This combination of lossless quality, transparency support, and universal compatibility makes PNG the professional standard for graphics and design assets.

AVIF: The Next-Generation Format

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec's intra-frame encoding. Developed by the Alliance for Open Media and standardized in 2019, AVIF achieves remarkable compression efficiency — roughly 50% better than JPG and measurably better than WebP at equivalent visual quality. It supports RGBA transparency, HDR, wide color gamut, and even a lossless encoding mode.

The critical limitation of AVIF is its incomplete ecosystem support. While Chrome 85+, Firefox 93+, and Safari 16.4+ can render AVIF natively in the browser, the format is not yet accepted by most image editors, older operating system viewers, design tools, print workflows, or legacy CMSs. This is the core reason developers and designers convert AVIF to PNG — to regain full ecosystem access while preserving image quality.

When Should You Convert AVIF to PNG?

The most common scenarios for converting AVIF to PNG are:

• Design tool compatibility. Figma, Sketch, Adobe XD, older versions of Photoshop and Illustrator, and most other design applications do not yet natively open or import AVIF files. Converting to PNG makes the asset immediately usable in any professional design workflow.
• Preserving transparency. If your AVIF source has a transparent background — common for logos, product cutouts, UI components, and icons — PNG is the correct lossless output format that preserves the alpha channel. JPG cannot carry transparency.
• Lossless archiving. For long-term image archives where pixel-perfect fidelity is required, PNG is more universally accessible than AVIF and is guaranteed to be openable by every tool for the foreseeable future.
• Print production workflows. Print-ready workflows, publishing tools, and professional print services universally support PNG. AVIF is not accepted by most prepress or print automation software as of 2026.
• CMS and platform uploads. Many content management systems, e-commerce platforms, and headless CMS APIs accept PNG as an upload format but may not yet support AVIF. Converting to PNG ensures your media pipeline works end to end.
• Client deliverables. Clients using standard image software may not be able to open AVIF files. PNG opens on every device without any special codec or viewer installed.

AVIF vs PNG: Detailed Comparison

PNG Quality and File Size Expectations

When converting AVIF to PNG, the output PNG file will typically be significantly larger than the source AVIF. This is expected and correct. AVIF achieves its small file sizes through aggressive lossy compression; PNG stores every pixel losslessly. A photograph that is 100 KB as an AVIF might be 800 KB–1.5 MB as a PNG. For web logos and flat-color graphics, the ratio is better — PNG compresses simple images with many identical pixels very efficiently.

The conversion introduces no additional quality loss. The PNG output is a pixel-perfect representation of what the AVIF decoded to — no further artifacts are introduced by the PNG encoding step. If you care about absolute image fidelity, the PNG is as good as the original AVIF's decoded output can be.

Transparency Handling

Both AVIF and PNG support full RGBA (32-bit) transparency. When your AVIF source contains transparent pixels — which is common for product photography with cutout backgrounds, UI component exports, logos, and icons — the transparency will be faithfully preserved in the PNG output. The alpha channel is carried through the conversion without modification.

This is one of the most important reasons to choose PNG as your output format over JPG. JPG has no transparency support — any transparent areas in the source will be replaced with a solid fill (typically white). If you need to preserve transparent backgrounds, PNG is the only correct lossless output format.

PNG vs WebP vs JPG: Choosing the Right Output

When you need to convert an AVIF image, the choice of output format depends on your use case:

• Use PNG when you need lossless quality, transparency support, maximum design tool compatibility, or you are creating assets for further editing. PNG is the correct choice for logos, UI components, product images with transparent backgrounds, and any image that needs to be edited further without quality loss.
• Use JPG when you need maximum platform compatibility for photographs without transparency — email newsletters, print workflows, legacy CMS uploads, and social media sharing where file size matters and transparency is not needed.
• Use WebP when you are targeting modern web delivery and want a good balance of compression and quality with transparency support. WebP is supported in all modern browsers and many CMSs, but not universally in design tools or print workflows.
