How this image converter works
Most online converters upload your file to a server, convert it there, and send it back. This one does the whole job inside the page you are looking at. Your browser already knows how to read JPG, PNG, WebP, GIF, BMP and usually AVIF, and how to write several of them. For formats it cannot handle alone, such as HEIC, TIFF, AVIF output and PDF pages, the page loads a small open-source decoder or encoder when you first need it, and runs that locally too.
That approach has a few pleasant side effects. It is quick, because nothing has to travel over the network. It keeps working if your connection drops after the page has loaded. And it is private in a way uploads cannot be, which matters for photos of family, scanned IDs, contracts and anything else you would rather not hand to a stranger's server.
Choosing the output format
If you are not sure which format to pick, a rough guide:
- JPG for photos you want to share, email or upload anywhere. Every device opens it.
- PNG for screenshots, logos, diagrams and anything with transparency or text.
- WebP or AVIF for images on your own website, where smaller files make pages faster.
- ICO for Windows icons and favicons; the favicon generator makes the full set.
There is a longer explanation in choosing between JPG, PNG, WebP and AVIF. For a specific pair, such as HEIC to JPG or PDF to JPG, the dedicated pages have settings and notes tuned to that conversion.
Questions people ask
Is this image converter really free?
Yes. There is no paid tier, no account and no watermark. The site costs little to run because your own device does the work.
Are my images uploaded?
No. They are read and converted by your browser. You can check by disconnecting from the internet after the page loads; standard conversions keep working.
Which formats can I convert?
You can open JPG, PNG, WebP, AVIF, HEIC, JPEG XL, GIF, BMP, TIFF, SVG, ICO, ICNS, PDF, Photoshop PSD, camera RAW, TGA, DDS, Radiance HDR and JPEG 2000 files, and save as JPG, PNG, WebP, AVIF, JPEG XL, GIF, BMP, TIFF, ICO or TGA.
Does it work on a phone?
Yes. It works in current mobile browsers on iPhone and Android. Very large photos may be scaled to fit the memory limits of some phones, and the tool tells you if that happens.
