Detect the real input format, decode it locally, and create JPG, JPEG, PNG, WebP, or browser-supported AVIF output.

The practical guide
Image formats differ in compression, transparency, animation, compatibility, and intended use. This converter inspects the actual file, then loads only the local decoder it needs.
JPG and JPEG use the same widely compatible, lossy photo format; the two options simply choose the filename extension. PNG is lossless and supports transparency. WebP can combine small files with transparency, while AVIF can be highly efficient but its encoding support still varies by browser.
HEIC/HEIF is common on newer phones but less universally supported, so converting HEIC to JPG or PNG makes sharing easier. GIF can contain animation, BMP is an older uncompressed bitmap, TIFF can hold multiple high-quality pages, SVG is vector-based, and ICO packages icon sizes.
Convert HEIC to JPG or PNG, PNG to JPG, JPG to PNG or WebP, WebP to JPG, AVIF to JPG, and TIFF to JPG or PNG. JPG output is useful for broad photo compatibility; PNG is the safer choice when the source has transparency.
JPEG cannot store transparent pixels, so the converter composites them onto your chosen background. JPG/JPEG and WebP quality controls trade detail for file size; PNG remains lossless. Converting JPG to PNG does not recover detail already removed by JPEG compression.
HEIC uses the main image, multi-page TIFF uses the first page, animated GIF exports the first rendered frame, sanitized SVG may lose complex features, and ICO uses its largest valid embedded resolution. AVIF output appears only when this browser proves it can encode a real AVIF image.

Questions, answered
No. Native codecs and bundled JavaScript decoders run locally in this page.
Choose JPG for broadly compatible photos, PNG for lossless graphics or transparency, and WebP for modern web delivery. AVIF is available only when your browser can encode it correctly.
Canvas AVIF encoding varies by browser. The option is disabled unless a runtime test returns an actual image/avif blob.
This converter intentionally exports one still frame and shows a warning when animation is detected.
Before rendering, the tool removes scripts, embedded HTML, event attributes, JavaScript URLs, and remote references. Complex SVG features may therefore change.
