How to use JPG to PNG Converter

  1. 01

    Choose your JPG

    Click to browse or drag a JPG in. It is read locally — nothing is sent to a server.

  2. 02

    Browser reads every pixel

    The image is decoded on an HTML canvas exactly as the JPG stores it, artifacts and all.

  3. 03

    Re-encoded losslessly to PNG

    The decoded pixels are written out as PNG with no recompression, so nothing further is lost in the format change.

  4. 04

    Download your PNG

    The PNG saves directly from your browser, ready for editing or anywhere a lossless format is required.

Settings guide

No settings — lossless by design
Every pixel of the JPG is copied into the PNG exactly as it is, right in your browser, so there is no quality option — nothing is recompressed and nothing is lost. Note the tool cannot add transparency: JPG has none to begin with.

About the formats

JPG

JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.

Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.

PNG

PNG is a lossless raster image format created in the mid-1990s as a patent-free replacement for GIF. It is the standard choice for screenshots, logos, UI graphics, and any image that needs transparency.

PNG preserves every pixel exactly and supports a full 8-bit alpha channel, so text and sharp edges stay crisp. The downside is size: photographs saved as PNG are far larger than the same image as JPG or WebP. Support is universal in browsers and editors, making it a safe default for graphics — just avoid it for large photo collections.

Troubleshooting

The PNG doesn't have a transparent background
Changing the format can't invent transparency — JPG stores no alpha channel, so the white (or any) background is real pixels. To actually remove a background you need a background-removal tool, not a format conversion.
The PNG is several times larger than the JPG
Expected: PNG stores photos losslessly, and photographic detail compresses poorly that way. The extra size does not mean extra quality — existing JPG artifacts are preserved, not repaired. Only convert to PNG when a workflow specifically requires it.
Do I need an account, and is the file uploaded?
No account and no upload: the conversion happens entirely in your browser, single files are free with no usage limit, and the image never leaves your device.
