Free Image Converter Online — Convert JPG PNG WebP AVIF GIF

Convert images between JPG, PNG, WebP, AVIF, GIF and BMP instantly. Batch convert multiple files at once. No software, no account, no file size limit for standard images.

Which image format should you use?

JPG/JPEG: best for photographs and complex images with many colors. Lossy compression — great file size reduction. Not ideal for logos or text. PNG: best for logos, icons, screenshots and images with text. Lossless, supports full transparency (alpha channel). Larger file size than JPG for photos. WebP: modern Google format offering 25-35% smaller files than JPG at equal quality. Supported by all major browsers (Chrome, Firefox, Safari 14+, Edge). AVIF: next-generation format with even better compression than WebP. Support is growing rapidly. GIF: limited to 256 colors, suitable only for simple animated images.

Conversion and quality settings

When converting from a lossless format (PNG) to a lossy format (JPG or WebP), you can set the output quality level (1-100). Quality 85 is the standard recommendation — it produces files 5-10x smaller than the original PNG with barely visible quality reduction. Converting from lossy to lossless (JPG → PNG) produces a larger file without quality recovery, since JPEG compression is irreversible.

FAQ

Does PNG to JPG conversion preserve transparency?

No. JPG does not support transparency. Transparent areas in a PNG become solid white (or a color you specify) when converted to JPG. To preserve transparency, convert to WebP or keep PNG format.

Can I convert multiple images at once?

Yes. Upload up to 20 images and convert them all to the target format in one batch. Download individually or as a ZIP archive.

Does JPG to PNG conversion improve quality?

No. JPEG compression is irreversible. Converting JPG to PNG creates a larger lossless file, but the original compression artifacts remain. The quality does not improve.

Is WebP compatible with all browsers?

Yes. WebP is now supported by all major browsers: Chrome, Firefox, Safari (14+), Edge and Opera. It is safe to use for any modern web project.

Can I convert RAW photos (CR2, NEF, ARW)?

RAW formats are not currently supported. Convert your RAW files to JPEG or PNG first using your camera software or Lightroom, then use our converter.

What is the maximum image size for conversion?

Each image can be up to 20 MB. Very large images (e.g. 50MP+ camera files) may take a few extra seconds to process.
