Can I compress AVIF without uploading?

Yes. Asset Melt encodes and re-compresses AVIF entirely client-side using WebAssembly. Your images never leave your device.

What quality should I use for AVIF?

For web photos, AVIF quality 50–65 usually matches JPEG 80–85 visually at half the file size. Use the before/after compare to verify.

Can I convert JPEG or PNG to AVIF?

Yes. Add JPEG, PNG, WebP, or other supported formats and set AVIF as the output format in the studio pipeline.

Does Asset Melt support batch AVIF compression?

Yes. Queue multiple files, set AVIF output once, and download the entire batch as a ZIP.

Compress AVIF imagesin your browser

AVIF delivers the smallest file sizes for the web, but tuning quality is tricky. Asset Melt compresses AVIF files client-side with full codec control, size-budget encoding, and batch support — convert to AVIF or re-compress existing AVIF files.

Why Asset Melt

Built for this exact job

Everything you need — no uploads, no accounts, no compromises.

Fine-tuned quality

Adjust AVIF quality, speed, and lossless mode. Preview before/after with a live compare scrubber to find the sweet spot.

Size-budget mode

Set a max file size and Asset Melt searches for the highest AVIF quality that fits — no guesswork.

Convert & re-compress

Encode JPEG/PNG/WebP to AVIF, or re-compress existing AVIF files that are larger than they need to be.

Batch AVIF export

Convert an entire folder to AVIF in one session. Download all optimized files as a ZIP.

How it works

Three stepsno upload step

Open the studio, process your files locally, and download — all in your browser.

Add your images

Drop AVIF files to re-compress, or add JPEG/PNG/WebP sources to convert to AVIF. Multiple files supported.

Configure AVIF encoding

Select AVIF output, set quality (50–65 is typical for web), adjust speed, or enable size-budget encoding for a target KB.

Compare and download

Use the before/after compare to verify visual quality, check byte savings, and export individually or as ZIP.

Why compress to AVIF?

AVIF (AV1 Image File Format) typically produces files 30–50% smaller than WebP and 50–70% smaller than JPEG at equivalent visual quality. That means faster page loads, lower bandwidth bills, and better Core Web Vitals scores.

Major browsers support AVIF natively. It is the best choice for hero images, product photos, and any asset where file size directly impacts performance.

Why use a browser-based AVIF compressor?

Desktop AVIF encoders exist, but they require installation and CLI knowledge. Cloud compressors upload your files to remote servers.

Asset Melt encodes AVIF using the @jsquash/avif WASM codec — the same engine family as Google Squoosh — running entirely in your browser. You get a visual interface, live preview, and batch export without installing anything or uploading anything.
