How to Convert JPEG to PNG Online

This tool takes a JPEG image, processes it with the sharp library (libvips) on our servers and returns a PNG image.

JPEG is lossy while PNG stores data exactly. The PNG file will be larger but not better: detail discarded by JPEG cannot be restored.

Property	JPEG	PNG
Full name	JPEG	Portable Network Graphics
Introduced	Joint Photographic Experts Group, 1992	W3C, 1996
Compression	lossy	lossless
Strengths	small photos accepted everywhere	lossless with full transparency; best for screenshots, logos, text and UI graphics
Limitations	no transparency; each re-save loses a little quality	photos become much larger than JPEG

On September 25, 2026 we ran the tool on our production server with a sample file: a 1920×1080 JPEG image, 182 KB.

Result: 182 KB → 355 KB, processed in 0.4 s. Output: a 1920×1080 PNG image.

Real sizes depend on the image content (detailed photos are heavier than flat graphics); the figures only show the order of change.

Up to 30 MB and 40 million pixels (about 8000×5000) per image.
The file is sent to our server for conversion and deleted as soon as processing ends, including when it fails.

No. PNG only stores exactly what is left in the JPEG; what was lost when the JPEG was compressed does not come back. The file just gets larger.

With our sample file: 182 KB → 355 KB. Your file may differ depending on its content.
