Auto-adjusts quality to meet the target. Uses binary search (max 6 iterations).
Auto matches source depth. 10-bit is standard for HDR content. 12-bit for maximum precision.
Your images are processed entirely in the browser using WebAssembly codecs.
No data is sent to any server. Ever.
Why Convert PNG to AVIF?
AVIF delivers 50-70% smaller files than PNG with near-identical visual quality. It supports both lossy and lossless compression, 10-bit color depth, and HDR. Converting PNG to AVIF is the most aggressive size reduction available for modern browsers.
How It Works
- Drop your files — drag and drop, click to browse, or paste from clipboard
- Instant conversion — SIMD-accelerated WebAssembly codecs process images in milliseconds, entirely in your browser
- Download — get individual files or batch download as ZIP
The Most Customizable Image Tool on the Web
Most online converters give you a single quality slider and call it a day. We expose every parameter that the underlying codec libraries support — chroma subsampling modes, PNG filter strategies, quantization with adjustable max colors, dithering intensity, speed/quality tradeoffs, progressive encoding, smoothing, and alpha channel control. No other browser-based tool offers this level of fine-grained control over your image output.
Blazing Fast — SIMD-Accelerated WebAssembly
Our codecs are compiled from industry-standard C libraries (libjpeg-turbo, libspng, libimagequant) with WASM SIMD instructions enabled, link-time optimization, and maximum compiler optimizations. Images convert in milliseconds, not seconds — even large files process near-instantly because everything runs at native speed directly in your browser, with no server round-trip.
Privacy & Security
Your images never leave your device. All processing happens locally in your browser using WebAssembly codecs compiled from industry-standard C libraries (libjpeg-turbo, libspng, libimagequant). No data is uploaded to any server. No tracking. No ads.
EXIF Metadata & GPS Privacy Scanner
Every JPEG you take with your phone embeds hidden metadata — camera model, lens info, shutter speed, ISO, date and time, and often your exact GPS coordinates. Sharing unstripped photos online can unintentionally reveal where you live, work, or travel.
Our tool automatically scans every image you drop for EXIF metadata and flags privacy-sensitive fields immediately. You'll see:
- ●GPS alerts — red badge and warning when location data is detected
- ●EXIF badge — green indicator when camera/technical metadata is present
- ●Hover preview — quick glance at camera, aperture, shutter speed, ISO, and focal length without clicking
- ●Full metadata panel — expand to see every EXIF field, GPS coordinates, and software info
All scanning runs entirely in your browser — your metadata is never sent anywhere. When you convert from JPEG to PNG, EXIF data is not carried over to the output, effectively stripping all metadata including GPS coordinates from the converted file.
