About Image Format Converter
Convert images between WebP, PNG, JPG, and AVIF formats — all in your browser, no upload required. Preserve transparency when converting from PNG to WebP or AVIF. Adjust quality settings per format. Useful for migrating sites to modern formats and reducing image weights without sacrificing visual quality.
How It Works
- Upload an image (drag-and-drop or click to browse)
- Pick the target format (WebP for smaller files, PNG for transparency, JPG for max compatibility)
- Adjust quality if needed (80-90% is the sweet spot for most use cases)
- Download the converted file

Frequently Asked Questions
- Which format produces the smallest files?
- AVIF for the absolute smallest, ~50% smaller than JPG. WebP for broad compatibility, ~25-35% smaller than JPG. Both support transparency. JPG only when you need universal compatibility.
- Does converting to JPG lose transparency?
- Yes — JPG doesn't support transparency, so any transparent areas become solid white (or another fill color). Use WebP or AVIF if transparency matters.
- Can I convert multiple images at once?
- Currently one at a time per session. For batches, open multiple tabs and process in parallel, or use a desktop tool.
