How it works

ConvertCabin draws your image onto a canvas inside this browser tab and re-encodes it in the new format — entirely on your device. The file is never uploaded, so there's no queue, no daily cap, and no account.

Most converters that rank for these searches upload your image to a server first. Because ConvertCabin does the work locally, it stays genuinely free, unlimited and private — and keeps working offline once the page has loaded.

About JPG and PNG

JPG is compressed and lossy; PNG is lossless. Converting JPG to PNG is useful when a tool requires PNG or you want to stop further quality loss while editing — though it can't recover detail the JPG already discarded, and the PNG file will usually be larger.

Frequently asked questions

How do I convert JPG to PNG?
Drop your JPGs above and download the PNGs. The conversion runs entirely in your browser.
Does converting to PNG improve quality?
No. PNG is lossless, so it won’t add back detail a JPG already lost — it just prevents further loss from here on.
Is anything uploaded?
No. Files are converted on your device and never sent anywhere.
What is a JPG file?
JPG (also written JPEG) is the most widely supported image format on the web. It uses lossy compression to keep files small, making it ideal for photos and sharing, though re-saving repeatedly slowly reduces quality.
What is a PNG file?
PNG is a lossless image format that supports transparency. It preserves every pixel exactly — great for logos, screenshots, and graphics with sharp edges — at the cost of larger files than JPG for photographs.
