How it works
Convert JPG images to PNG on your device. Preview the image and check its actual size before downloading. Choose the source image, check the preview and settings, then process it. Download the result after checking its format and dimensions.
Example
JPG → PNG · 1200 × 800 px
When to use this tool
Use PNG for a lossless re-encoding and supported transparency. Converting cannot recover detail already lost in the source.
Supported formats & limits
Accepted input: JPG. Static JPEG, PNG, WebP and browser-decodable AVIF; HEIC/HEIF uses a locally loaded WASM decoder. Up to 20 MiB per image, 24 megapixels, 20 files sequentially. Lower limits apply on limited devices. Re-encoding removes source metadata; color profiles, HDR, and high bit depths are not preserved exactly. Animated images and SVG are not supported. PNG conversion can increase file size.
Something isn’t working ↗Good to know
My output is larger than expected
Use PNG for a lossless re-encoding and supported transparency. Converting cannot recover detail already lost in the source. Dimensions and file size are different. PNG preserves detail but can be larger than JPG. Try JPEG or WebP with a lower quality setting for photos. Compare the actual size shown before downloading.
