Image Converter
Convert images to PNG, JPEG, WebP, or an ICO favicon.
JPEG and WebP use the quality slider. PNG is lossless, so it ignores quality. Everything is converted in your browser and never uploaded.

Common questions
Are my images uploaded to a server?
No. Decoding and re-encoding happen in your browser with the canvas API, so your images never leave your device. There is no upload and no storage.
Which formats can I convert between?
You can load PNG, JPG, WebP, GIF, BMP, SVG, and AVIF images and convert them to PNG, JPEG, WebP, or a multi-size ICO favicon. Reading AVIF and SVG depends on your browser, and the outputs are the formats browsers can create without any plugin.
Can I make a favicon.ico?
Yes. Choose ICO as the output and the tool builds a single .ico that packs 16, 32, and 48 pixel tiles with transparency preserved, which is exactly what a website favicon.ico needs. It works from any source image, including an SVG logo.
What does the quality slider do?
JPEG and WebP are lossy formats, so the slider trades file size for visual fidelity: lower quality means a smaller file. PNG is lossless and ignores the slider, so it always keeps full detail.
Why is there a background colour option for JPEG?
JPEG has no transparency. When you convert a transparent PNG or WebP to JPEG, the see-through areas are filled with the background colour you pick, which stops them from turning black.
Can I convert several images at once?
Yes. Add as many images as you like, pick one output format and quality, and each file is converted with the same settings. Download them one at a time, or use Download .zip to get them all in a single archive.
Can I resize images while converting?
Yes. Set a longest-edge limit and any image larger than it is scaled down to fit, keeping its aspect ratio. Smaller images are left as they are, so nothing is ever upscaled and blurred.
