About the Image Converter

Image Converter is a free online tool that converts your images between JPEG, PNG, WebP, and AVIF formats — with no sign-up, no watermarks, and no file size restrictions beyond 20 MB.

How It Works

Your image is uploaded to our server where Sharp (built on libvips) reads it and re-encodes it in the target format you select. Sharp uses libvips's highly optimised pipeline for format conversion, which is significantly faster and more memory-efficient than ImageMagick or PIL for large images.

Encoding settings per format:

• JPEG — quality 92, standard 4:2:0 chroma subsampling
• WebP — quality 90, Google's modern lossy format with better compression than JPEG at similar quality
• AVIF — quality 80, the newest format based on AV1; excellent compression but slower to encode
• PNG — lossless, minimal zlib compression for fast decode

What Is sortout.app?

sortout.app is a growing collection of focused web tools, each designed to do exactly one thing well. Every tool is free, requires no account, and is built to load fast anywhere.

Format Comparison

• JPEG — widely supported; good for photos; no transparency support
• PNG — lossless; supports transparency; larger files than JPEG/WebP for photos
• WebP — smaller than JPEG at comparable quality; supports transparency; supported in all modern browsers
• AVIF — smallest file size of all formats; HDR and wide color gamut support; requires Safari 16+ or Chrome 85+

Privacy

Your files are sent to our server over HTTPS, processed immediately, and deleted — never stored or shared. See our full Privacy Policy.

Frequently Asked Questions

Is this tool free?

Yes, completely free with no usage limits.

Does converting to PNG lose quality?

No. PNG is a lossless format, so converting any image to PNG preserves full pixel accuracy. However, the PNG file will typically be larger than the original JPEG or WebP.

Can I convert a GIF or TIFF?

Yes — GIF and TIFF can be used as input formats. For GIF, only the first frame is converted. Output formats are JPEG, PNG, WebP, and AVIF.

Why is my AVIF file smaller than my WebP?

AVIF uses the AV1 video codec's intra-frame compression, which is more efficient than WebP's VP8-based algorithm. The tradeoff is slower encoding time.
