How to use the JPG to PNG
- 01
Choose your JPG
Click to browse or drag a JPG in. It is read locally — nothing is sent to a server.
- 02
Browser reads every pixel
The image is decoded on an HTML canvas exactly as the JPG stores it, artifacts and all.
- 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.
- 04
Download your PNG
The PNG saves directly from your browser, ready for editing or anywhere a lossless format is required.

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.
Privacy and file handling
Processing happens in your browser, so the selected file is not uploaded.
- Browser-local processing
- The conversion runs on this device after the page loads.
- No file upload
- The source image does not need to leave your browser.
- No model API
- This basic tool does not send the file to an AI model.
JPG to PNG 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.
FAQ
- Why convert JPG to PNG?

- Does conversion happen in the browser?
- Yes. Your JPG files are converted entirely within your browser. Nothing is uploaded, so your images stay private.
- Is there a file size limit?
- Free accounts can upload files up to 50 MB. Paid users can upload up to 200 MB.
- Does converting to PNG add transparency to my JPG?
- No. Changing the format can't invent transparency — JPG stores no alpha channel, so the background stays exactly as it was. To actually remove a background you need a background-removal tool, not a format conversion.
- Why is the PNG several times larger than the JPG?
- That's expected: PNG stores photos losslessly, and photographic detail compresses poorly that way. The extra size doesn't mean extra quality — existing JPG artifacts are preserved, not repaired.
