Next-Gen Compression

AVIF uses the AV1 codec to produce images far smaller than traditional JPEG — ideal for web use where bandwidth and load speed matter.

Cloud Encoding

AV1 encoding is computationally intensive, but cloud servers handle the heavy lifting so your own device stays responsive and unburdened.

Growing Compatibility

AVIF support is now built into all major browsers and recent operating systems — your converted slide images will display almost everywhere.

About formats

PPT is the binary file format of Microsoft PowerPoint, the presentation software first released on April 20, 1987 for the Apple Macintosh and later ported to Windows. The PPT format stores presentations as OLE2 compound documents — a structured binary container developed by Microsoft that organizes slides, text content, images, charts, animations, transitions, speaker notes, and embedded objects across multiple internal streams. Each slide is composed of shape records describing text boxes, auto-shapes, images, tables, and other elements with associated formatting properties including fonts, colors, positioning, and animation sequences. The format evolved substantially through multiple PowerPoint versions, with the PowerPoint 97 release establishing the compound document structure that remained standard through PowerPoint 2003. One advantage is universal recognition — PPT files are understood by virtually every presentation application across all platforms, from Microsoft Office to LibreOffice Impress, Google Slides, and Apple Keynote, making it one of the most portable document formats ever created. The format's mature feature set is another strength: PPT files support complex slide masters, custom animations with timing sequences, embedded multimedia, OLE-linked objects, and VBA macros for automation. Although Microsoft introduced the XML-based PPTX format with Office 2007, the binary PPT format remains widely encountered in archived presentations, corporate document repositories, and organizations that maintain compatibility with older PowerPoint versions.
Developer: Microsoft
Initial release: April 20, 1987
AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.

Frequently Asked Questions

Why convert PPT to AVIF?

AVIF delivers superior compression — your slide images will be significantly smaller than JPEG or PNG equivalents while retaining sharp visual quality.

What is AVIF?

AVIF is a modern image format based on the AV1 video codec. It offers better compression ratios than JPEG and WebP, with support for HDR and transparency.

Which browsers support AVIF?

Chrome, Firefox, Safari, Edge, and Opera all support AVIF. Mobile browsers on Android and iOS have added support in recent versions as well.

How do I open AVIF on my desktop?

Windows 11 supports AVIF natively. On older systems, apps like IrfanView, GIMP, or the Windows AVIF extension handle it. macOS Preview works from Ventura onward.

Is PPT to AVIF free?

Convertio provides free PPT to AVIF conversion for standard use. Premium accounts are available for users who need higher throughput.

Does AVIF support transparency?

Yes — AVIF supports alpha channels. If your PPT slides have transparent backgrounds, that transparency can carry through to the AVIF output.
