About Convert Image Format

Format mismatches block uploads constantly: a form that only accepts JPG, a design tool that wants PNG, or a HEIC photo that Windows won't open. Converting between formats fixes compatibility and can dramatically change file size.

This converter switches images between JPG, PNG, and WebP in your browser. Each format has a job: JPG for photographs, PNG for transparency and crisp graphics, WebP for the smallest files on the modern web.

Tips for better results

✓Converting PNG screenshots to JPG can cut size 5–10× when transparency isn't needed.
✓Converting JPG → PNG never improves quality — it only makes the file bigger.

Frequently Asked Questions

What output formats are supported? +

JPG, PNG, WebP, and AVIF are supported as output. AVIF offers the smallest file size for photos in modern browsers. PNG is best for transparency. WebP balances quality and size well.

What input formats can I upload? +

You can upload JPG, PNG, WebP, GIF, BMP, SVG, ICO, AVIF, TIFF, and HEIC files. Animated GIFs are converted as a still frame (first frame only).

Can I convert multiple images at once? +

Yes — add up to 10 images at once. They all convert to the same target format, and each gets its own download button.

Does PNG to JPG conversion lose quality? +

JPG is lossy by nature, so converting from PNG to JPG slightly reduces quality depending on the quality setting. At 90%+ the difference is barely visible.

Will transparent PNGs convert correctly to JPG? +

Transparent areas will be filled with white when converting to JPG, since JPG does not support transparency. Use PNG or WebP to keep transparency.

Are my images private? +

Yes. All conversion happens locally in your browser using the Canvas API. Nothing is ever uploaded.
