How Does Image Conversion Work?
Your browser decodes the source image using the Canvas API, then re-encodes it using industry-grade WebAssembly engines — MozJPEG for JPG, libwebp for WebP, and a lossless encoder for PNG. Everything runs locally on your device; your images are never sent to a server.
Which Format Should I Use?

Frequently Asked Questions
Does converting change image quality?
Converting to PNG is always lossless — no quality loss. Converting to JPG or WebP uses the quality slider you set. At 85%, the result is visually identical to the original.
Can I convert GIF or BMP files?
Yes — any format your browser can display (GIF, BMP, TIFF, AVIF) can be used as input. Output is JPG, PNG, or WebP.
Why convert to WebP?
WebP files are 25–35% smaller than equivalent JPG files with the same visual quality, making pages load faster. All modern browsers support it.
Is there a file size limit?
No server-side limit. Processing happens in your browser, so very large images may take a few seconds depending on your device.
