About the Image Format Converter
Upload any browser-readable image and instantly see it re-encoded as JPEG, PNG, and WebP side by side, with the file size of each so you can pick the smallest one for the job — WebP is usually the smallest for photos, PNG is best for graphics with transparency or flat colors.
Key Features
- Converts to all three formats in one pass — no need to run the tool three times.
- Adjustable quality slider for the lossy formats (JPEG, WebP); PNG stays lossless.
- 100% client-side — nothing is uploaded to a server.
