PNG is the gold standard for lossless storage, but it is rarely efficient for web delivery. AVIF, the newest widely supported image format, can represent the same visual content at a fraction of the PNG file size — and it preserves the alpha channel, so transparent backgrounds and soft edges come through intact.
Enhydra RPO converts up to 200 PNGs to AVIF in a single batch. The result is a ZIP ready to deploy, or individual files for a direct workflow.
For photographic PNG sources, AVIF's lossy mode typically produces files that are dramatically smaller — often 60–80% less than the PNG original — because modern lossy compression is fundamentally more efficient than lossless storage for photo content. For flat-color illustrations, icons, and diagrams, the difference is smaller but still real: lossless AVIF commonly undercuts PNG by 20–40%.
The exact savings depend on image complexity. After converting, spot-check a few outputs to confirm the quality meets your standard before deploying the full batch.
AVIF has a proper alpha channel — it is not a format that fills transparent areas with a background color the way JPG does. Transparent pixels, semi-transparent drop shadows, and soft-edge cutouts all convert from PNG to AVIF without any fill applied. This makes the PNG-to-AVIF path suitable for UI assets, logos, and product images that rely on a clear background for overlaying on colored surfaces.
AVIF is supported in Chrome 85+, Firefox 93+, Edge (Chromium-based), and Safari 16+. Together these cover well above 90% of current global browser traffic. The notable gap is Safari 15 and below, still present on older iPhones and Macs. For sites where that audience matters, serving AVIF via the HTML <picture> element with a PNG or WebP fallback is the standard approach — capable browsers get AVIF, others fall back automatically. No JavaScript required.
Yes. AVIF supports full alpha transparency. Transparent and semi-transparent areas in the PNG source carry over to the AVIF output without any fill applied.
For most audiences, yes — but Safari 15 and below does not support AVIF. Using a PNG or WebP fallback via the HTML picture element ensures older browsers still see the image.
Stack the Compress tool in the same run to dial quality from 1 to 100 or enter a kilobyte target. Both the format conversion and compression run in one pass, so there is no double-encoding penalty.
Up to 200 files per run, each up to 80 MB. Multiple outputs are packaged as a single ZIP for download.
