Image Converter

// One converter instead of five tabs

This tool reads JPG, PNG, WebP, HEIC, and AVIF, and writes out JPG, PNG, or WebP; browsers can decode more formats than they can encode, and those three cover what software actually asks for. Drop in whatever you have, pick the output, done.

Picking the output is the real decision. JPG opens everywhere and keeps photos small, but has no transparency, so alpha regions get flattened onto white. PNG is lossless with full transparency and pays for it in file size. WebP lands about 25 to 35 percent smaller than either at similar quality and keeps transparency, with the caveat that some older desktop software cannot open it.

// How each format gets handled

WebP and AVIF decode with your browser's built-in support; HEIC, which browsers cannot read, goes through a WebAssembly build of libheif loaded on demand. Whatever came in, the pixels are drawn to a canvas and re-encoded to your chosen output, with a quality slider available for the lossy formats, JPG and WebP. If your browser is too old to decode an AVIF, the tool says so outright rather than failing silently.

The canvas re-encode strips EXIF metadata from every output, so GPS coordinates and camera details never travel with the converted file. It also means no upload: conversion is local from the first byte to the last, and the tool keeps working offline once the page has loaded.

// fair questions

Do the images I convert get uploaded?

No. All decoding and encoding is done by your browser on your own device, so your files never leave it and nothing is sent over the network during conversion.

Which formats can it read and write?

It reads JPG, PNG, WebP, HEIC, and AVIF. It writes JPG, PNG, and WebP, because those are the formats browsers can encode. That covers converting away from the two troublemakers, HEIC and AVIF, into anything portable.

What happens to metadata like camera and location info?

It is stripped. Re-encoding through a canvas discards EXIF data, so the converted file carries no GPS coordinates or camera details. Good for privacy when sharing; a limitation if you need metadata to survive.

Does it work without an internet connection?

Yes. Once the page has loaded, every conversion runs locally, so you can go offline and keep converting. Nothing about the process requires a server.
