Why convert JPG to PNG?
PNG is a lossless format, so converting a JPG to PNG stops further quality loss when you plan to edit and re-save the image repeatedly. PNG also supports transparency and renders sharp edges and text cleanly, which JPG's compression can blur.
How it works in your browser
Each JPG is decoded and re-encoded as PNG on a canvas, entirely on your device — nothing is uploaded. Convert a whole batch at once and download them together.
What to expect
Converting JPG to PNG will not recover detail the JPG already lost — it preserves the current image without adding new compression. Because PNG is lossless, the resulting file is often larger than the original JPG, which is the trade-off for editable, lossless quality.
When to use PNG
Choose PNG for screenshots, logos, diagrams, and any image you will edit again, or that needs transparency. For sharing photographs where small size matters, JPG or WebP is usually better.
