How your files are processed
Files are uploaded and processed on our servers, then made available for download.
What this tool does
Source pixels (or vector paths) are rasterized as required, then encoded to AVIF.
ICC profiles may be copied, transformed, or stripped depending on encoder defaults.
- PNG family — PNG: DEFLATE-filtered scanlines; optional alpha; gamma chunk optional.
- AVIF family — AVIF output: HEIF wrapper around AV1 intra frames.
- Encode traits — Raster exports fix dimensions, subsampling, and ICC embedding per encoder—vectors rasterize to one pixel grid.
How to convert PNG to AVIF?
- Choose file — upload a PNG file that matches this page (allowed extensions apply).
- Convert to AVIF — lock the target format if needed, then start the job and wait for status updates.
- Download — grab the finished file from your job link before the retention window ends.
Why convert PNG to AVIF?
Each hop trades smaller files against visible defects; switching formats can trade alpha, animation, or HDR side data against simpler decode surfaces.
Prefer AVIF when alpha, animation, HDR sidecars, or ICC handling matter more than the smallest on-disk result.
Vectors versus rasters trade infinite zoom against predictable pixel weight—prefer AVIF when bitmap semantics matter more than editable paths.
Common reasons to convert PNG to AVIF
- Point Imgix URLs at AVIF when CDNs rewrite PNG masters already in S3 buckets.
- Emit AVIF from GitLab CI before Slack when reviewers diff PNG screenshots.
- Serve AVIF from next/image when builds optimize assets but archives stay PNG.
- Stage AVIF on Marketing Cloud when ZIP packs must match hosted filenames.
- Sync AVIF into DSM when Sketch stayed PNG but the style guide expects AVIF.
Will converting PNG to AVIF affect quality or file size?
Pixels decoded from the source usually remain visible after conversion.
Another lossy step softens edges; JPEG detail lost earlier never returns—size exports to the screen or print size you need.
PNG vs AVIF
PNG (PNG)
PNG compresses bitmaps without throwing pixels away and supports smooth transparency. UI shots, logos, and crisp diagrams often ship as PNG. Photo-sized PNGs are usually heavier than JPEG because nothing is discarded.
AVIF (AVIF)
AVIF uses modern compression related to AV1 and can shrink photos sharply where decoders exist. Social sites and older viewers sometimes reject it, which pushes creators back to JPEG or PNG for guaranteed opens.
PNG to AVIF changes which apps open first—Chrome, Photoshop, and Outlook each bind double-click actions to the new extension.
Troubleshooting
- Lossy recompression: blocking, ringing, and banding show first on text, edges, and skies—inspect at 100% zoom.
- Alpha: formats without an alpha channel (JPEG, most HEIC stills) cannot produce real transparency in the output unless you supply it elsewhere.
- Dimensions and DPI: raster outputs fixed pixel grids—upscaling later softens detail; embedded ICC profiles may shift colors across viewers.
- Decode support: older viewers may lack AVIF decoders (AVIF, WebP); verify the destination stack.
- Upload fails or stalls: refresh the page, try a different browser, or disable strict content blockers for this session.
