Which Image Format Should You Choose?

For photographs and web images, JPG is the standard. If optimising for a modern website, WebP delivers 25-35% smaller files than JPG with no visible quality difference.

For graphics with transparency — logos, icons, overlays — PNG is the go-to format. For even smaller transparent images on the web, WebP supports transparency too.

For scalable graphics like logos and illustrations, SVG is unmatched. As a vector format, SVG scales to any size without losing quality.

For iPhone photos, Apple saves in HEIC format. Most non-Apple platforms cannot open HEIC natively, so converting HEIC to JPG is essential for sharing.

For maximum web performance, AVIF is the newest and most efficient — up to 50% smaller than JPEG.

Frequently Asked Questions

What is the best free online image converter?

FileConvertTool offers free image conversion between 10+ formats including PNG, JPG, WebP, SVG, GIF, BMP, TIFF, ICO, HEIC, and AVIF. No registration, no watermarks.

Can I convert images without losing quality?

Converting between lossless formats (PNG, BMP, TIFF) preserves full quality. Converting to JPG involves lossy compression, but at quality 85-90% the difference is virtually invisible.

How do I convert HEIC photos from my iPhone?

Use the HEIC to JPG converter — upload your iPhone photo and it converts to universal JPG in seconds. Works on any device.

What image format has the smallest file size?

AVIF produces the smallest files at equivalent quality, followed by WebP, then JPG. For graphics, SVG is often smallest because it stores shapes, not pixels.

Can I convert multiple images at once?

Yes supports batch uploads. Drag and drop multiple files and convert them all at once.
