Convert AVIF to PNG in your browser

Decode AVIF natively in your browser and re-encode as lossless PNG with the alpha channel preserved. Nothing is uploaded.

Quick Start

How it works

Pick an image, tune the options, then download the result. Everything runs in your browser.

  1. 01

    Pick an AVIF

    Choose any .avif file. Decoding uses the browser's built-in AVIF support.

    Files stay in memory as an HTMLImageElement — the original bytes are never uploaded, and EXIF metadata is preserved until you explicitly transform it.

    Decode locally

    The browser draws AVIF pixels to a hidden canvas — nothing is uploaded.

    Encoder quality is exposed where the format supports it — JPEG and WebP get a 0–1 quality slider; PNG is lossless. Options re-render the canvas immediately.

    Encode PNG

    Re-encode the canvas as a lossless PNG, keeping the alpha channel intact.

    Pixel work runs on the Canvas 2D context — drawImage resamples with the browser’s bilinear filter and getImageData/putImageData back per-pixel passes.

    Download PNG

    Save the .png file — works in every PNG-aware editor.

    Downloads ship via a hidden anchor with an object URL — no server round-trip, and the file on disk is untouched. The output filename inherits a sensible suffix.

Pro tips

Browser-only image work that scales

Convert with quality control

JPEG/WebP let you pick a 0–1 quality. Default 0.92 is a good compromise of size and visible quality.

PNG isn’t free

Use PNG only for transparency or sharp edges. For photos, WebP is smaller at the same perceived quality.

Strip EXIF for privacy

Photo EXIF often contains GPS, camera model, and timestamps. Strip before sharing public uploads.

Watch the colour profile

Convert to sRGB before web export. Wide-gamut images render oversaturated in non-managed browsers.

AVIF when it’s available

AVIF beats WebP on size at the same quality. Detect support via <picture> with fallbacks.

Lazy-load below the fold

Add loading="lazy" on <img>. The browser handles scheduling — no IntersectionObserver needed.

Use Cases

When to use this tool

Common workflows it speeds up.

Editor compatibility

Most editors still expect PNG over AVIF. Decoded into a Canvas 2D context — original bytes never leave the tab, so you can process customer-uploaded photos, internal screenshots, or sensitive diagrams without privacy concerns.

px-perfect

Transparency intact

Alpha channel is preserved byte-for-byte. Encoders expose quality 0–1 where the format supports it (JPEG, WebP); PNG and AVIF stay perceptually lossless. Pick 0.85 for web, 0.95 for archival, 0.7 for thumbnails.

quality-tunable

Pipeline ingest

Convert AVIF assets into PNG-only build steps. Pair with the EXIF Stripper before sharing user-uploaded photos publicly. Camera serial numbers, GPS coordinates, and timestamps often hide in image metadata and leak more than the picture itself.

format-aware

Tool-chain bridge

PNG is the lingua franca of image tooling. Output preserves colour profile (sRGB) so it renders consistently across browsers, monitors, and print pipelines. Wide-gamut workflows can opt into Display P3 for modern Apple devices.

EXIF-safe

Quick previews

PNG opens instantly in any image viewer. Re-runs only on option changes, never on window resize, so the canvas stays responsive on large images. drawImage uses the browser's bilinear filter for fast resampling.

client-side

Browser fallback

Older Safari builds prefer PNG over AVIF. Downloads as .png, .jpg, .webp, or .avif with the correct MIME so editors apply native handling on save. The filename inherits a sensible suffix derived from the input.

FAQ

Frequently asked questions

Only browsers with native AVIF decode — Chrome 85+, Firefox 93+, Safari 16+.
PNG itself is lossless. Any compression already baked into the AVIF stays.
Yes — alpha channels are kept in the PNG output.
No. The conversion runs locally in your browser — your file never leaves the device.
AVIF is a modern lossy codec; PNG is lossless. PNGs are usually several times larger.
