How it works
Upload your image
Drag and drop or click to upload any image — PNG, JPEG, WebP, AVIF, GIF, BMP, SVG, ICO, or Apple HEIC/HEIF from iPhone.
Choose output format
Pick any target format: PNG (lossless), JPEG, WebP, AVIF (modern efficient), BMP (uncompressed), or ICO (icon/favicon).
Adjust quality (optional)
For lossy formats (JPEG, WebP, AVIF) drag the quality slider 10–100%. Higher = better quality, larger file size.
Convert & Download
Click Convert & Download — the file is generated and saved instantly. Nothing is uploaded to any server.
Common use cases
HEIC to JPEG/PNG (iPhone photos)
Convert Apple HEIC photos taken on iPhone and iPad to universal JPEG or PNG for sharing on Windows, Android, and web platforms.
PNG or JPEG to WebP / AVIF
Convert legacy images to modern WebP or AVIF to cut file sizes by 25–50% for faster websites and better Core Web Vitals scores.
Any image to ICO (favicon)
Convert a PNG, JPEG, or SVG logo to ICO format for website favicons or Windows application icons with no extra software.
Convert for compatibility
Convert modern WebP or AVIF images to JPEG or PNG for older apps, email clients, or social platforms that require universal formats.
Frequently asked questions
Can I convert HEIC (iPhone) photos?
Yes — HEIC and HEIF files from iPhone, iPad, or Mac are fully supported as input. Decoding runs entirely in your browser using a JavaScript library — nothing is uploaded to a server. Convert to JPEG or PNG for universal compatibility.
What input and output formats are supported?
Input: PNG, JPEG, WebP, GIF (first frame), BMP, AVIF, SVG, ICO, and HEIC/HEIF. Output: PNG, JPEG, WebP, AVIF, BMP, and ICO.
What is AVIF and should I use it?
AVIF (AV1 Image File Format) offers excellent compression — often 50% smaller than JPEG at equivalent quality. All modern browsers support it (Chrome 85+, Firefox 93+, Safari 16+). Ideal for web images.
Does converting to JPEG reduce quality?
Yes — JPEG uses lossy compression. A quality of 85–92% is nearly identical to the original visually. Repeatedly converting between lossy formats degrades quality each time.
What size is the ICO output?
ICO output uses the original image dimensions up to a maximum of 256×256 px (the ICO specification limit). For favicon use, start with a square image at 32×32 or 64×64 px.
Is my image uploaded to a server?
No. All conversion runs in your browser using the HTML5 Canvas API and a client-side HEIC decoder. Your images never leave your device.
