JPG to PNG · single image
Convert JPG to PNG
Convert one JPEG image to PNG without uploading it.
Your image bytes stay in this browser. There is no upload, account, or server fallback.
1. Choose one image
Exactly one static image, up to 25 MiB and 64 MP. Animated images and mismatched file types are rejected.
2. Choose conversion settings
Pixel dimensions stay unchanged. EXIF orientation is applied once and metadata is removed by re-encoding.
PNG preserves the decoded JPG pixels but cannot restore transparency or detail already lost in the JPEG source. It may also be larger than the original file.
3. Result
IDLE — Choose one JPG or JPEG image to begin.
What this conversion changes
The source is decoded upright in sRGB and encoded into the requested format. Pixel width and height remain the same; EXIF, IPTC, XMP, ICC, and orientation metadata are not copied.
The requested encoder MIME is verified before a download is offered. Refentra never silently returns a different format, and your original file remains untouched.
