Convert Image Format Online — JPG, PNG, WEBP, AVIF & HEIC
The Format Converter changes any image to the format you need — JPG, PNG, WEBP, or AVIF — and accepts HEIC files from iPhones so you can convert them straight to JPG or PNG.
Perfect when a website or app only accepts a specific format. Everything runs in your browser, so your files stay private.

Frequently Asked Questions
Got questions? We've got answers.
How do I convert an image to another format?▼
Upload your image, choose the target format (PNG, JPEG, WEBP, or AVIF), and download the converted file. It's instant and runs in your browser.
Can I convert HEIC to JPG?▼
Yes. HEIC and HEIF files from iPhones are decoded in your browser and can be converted to JPG, PNG, or WEBP.
What is AVIF?▼
AVIF is a next-generation, patent-free image format with excellent compression. You can convert to AVIF in browsers that support it (Chrome/Edge).
Will converting reduce quality?▼
Converting between lossless formats (like PNG to PNG) keeps quality. Converting to lossy formats like JPEG applies compression — adjust the quality slider to balance size and quality.
Is the converter free?▼
Yes, completely free with no sign-ups, watermarks, or limits.
Are my images uploaded to a server?▼
No. All conversion happens locally in your browser — your images never leave your device.
Why can't I choose AVIF output?▼
AVIF encoding isn't supported by every browser (notably Firefox). The option is hidden automatically when your browser can't encode it.
Does the converter keep transparency?▼
PNG keeps transparency. JPEG doesn't support transparency, so transparent areas become white.
