Image Converter FAQ

Is the image converter free? Do I need to sign up?

Yes, it is completely free. There is no account, no sign-up, and no watermark, and you can convert as many images as you like. The tool is supported by advertising rather than fees.

Which image formats can I convert?

You can convert to PNG, JPG, WebP, AVIF, and ICO. You can convert from those formats plus HEIC, the format iPhones use for photos. So an iPhone HEIC can become a JPG, a square PNG can become an ICO favicon, and so on. The format guide explains when to use each one.

Can I convert several images at once?

Yes. Drop in a batch and the converter processes them together, up to 50 images at a time. When more than one image is converted you also get a Download all button to save them in one go.

Is there a file size limit?

There is no fixed file size limit. Because everything runs in your browser, the practical ceiling is your device's available memory rather than a server cap. The one set limit is 50 images per batch.

Are my images uploaded to a server?

No. The conversion runs entirely in your browser, on your own device, so your images are never uploaded anywhere. For newer formats like AVIF and HEIC the browser fetches a small open-source codec, but your actual photos still never leave your device. See the privacy policy for more.

Does converting an image reduce its quality?

Converting to a lossless format like PNG does not reduce quality. Converting to a lossy format like JPG, WebP, or AVIF can, but at a high quality setting the difference is usually invisible, and you can control it with the quality slider.

What are WebP and AVIF, and when should I use them?

WebP and AVIF are modern web formats that produce smaller files than JPG or PNG at the same quality, and both support transparency. WebP is typically 25 to 35 percent smaller than JPG or PNG and is supported by every major browser. AVIF usually makes the smallest files of all, though it takes a little longer to create and is newer. Use either when you want faster-loading images on a website. The format guide compares them side by side.

Why did my transparent PNG turn white after I converted it to JPG?

JPG cannot store transparency, so the converter fills transparent areas with white before saving, which keeps them from turning black. If you need to keep a transparent background, convert to PNG, WebP, or AVIF instead.

How do I convert a HEIC photo from my iPhone to JPG?

Open the converter, drop in your .heic file, choose JPG as the output, and download the result. It all happens in your browser, so the photo is never uploaded. The HEIC to JPG guide has the full step-by-step.

How do I make a favicon from a PNG?

Convert a square PNG to ICO. The converter builds a multi-size .ico file with 16, 32, 48, and 256 pixel versions that works as a website favicon. Rename it favicon.ico and add it to your site's root folder. The favicon guide walks through it and includes the HTML to install it.

Why did my HEIC photo fail to convert?

Occasionally the browser's HEIC decoder cannot read a particular file and the converter marks it could not decode. Remove it and try adding it again. If it still fails, on your iPhone you can open the photo and re-save or screenshot it, or switch to the Most Compatible camera format so new photos are saved as JPG.
