The output control is fixed to PNG on this page, so the conversion cannot accidentally produce another JPG or a WebP file.

Why this tool
Make a lossless working copy without sending the source away
JPG and PNG solve different problems. JPG is efficient for photographs because it uses lossy compression, while PNG stores decoded pixels without adding another lossy generation. Converting a JPG to PNG can be useful before adding annotations, placing the image into a workflow that requires PNG, or avoiding another round of JPG compression. It does not reverse damage already present in the source.
The conversion keeps the source pixel dimensions. A 2400 by 1600 JPG produces a 2400 by 1600 PNG unless you separately resize or crop it. File size can increase considerably because PNG is not optimized for ordinary photographic detail in the same way as JPG. Check the downloaded byte size before using PNG for email, a government portal, or a web page with a strict upload limit.
JPG files do not contain an alpha transparency channel. Changing the filename or encoding the pixels as PNG cannot identify a subject and remove its background. If transparency is the real goal, use the background removal tool and inspect difficult edges such as hair, glass, shadows, and fine product details before download.
FileGizmo reads the selected JPG inside your browser and sends the conversion job to a dedicated local worker. The resulting PNG is exposed as a temporary browser object for preview and download. No account, remote conversion queue, or server-side copy is involved. Keep the original JPG as the archival source, and open the downloaded PNG outside the browser before deleting anything important.
Simple by design
Convert JPG to PNG in three clear steps
- 1
Choose the JPG or JPEG file you want to convert
- 2
Check the source dimensions and confirm PNG as the fixed output
- 3
Convert locally, inspect the preview, and download the PNG
Built for the whole job
Everything you need
Pixel dimensions stay unchanged
Format conversion does not resize or crop the image. The downloaded PNG uses the same width and height as the decoded JPG source.
Honest transparency handling
JPG cannot contain transparent pixels. The converter keeps the visible image as it is instead of claiming that a format change can remove a background.
Nothing is uploaded, and you can verify it
Processing runs on this device. Open the browser’s Network panel while the tool works and you will see no file upload request to FileGizmo. Temporary previews use local browser URLs, and closing or resetting the page releases them instead of leaving a server copy behind.
No limits, no watermarks
Use the tool without a daily task counter, account wall, output watermark, or artificial upload cap. FileGizmo does not meter a transfer it never receives. Available memory, processor speed, browser canvas limits, and the file format itself set the honest practical boundary.
Works on any device, and offline after first load
Use a current browser on desktop, Android, iPhone, or iPad without installing an app. Once this tool and its required assets load, the cached workflow works without a connection. Large jobs are usually more comfortable on a desktop with additional memory.

Frequently asked questions
Will converting JPG to PNG improve image quality?
No. PNG prevents additional lossy encoding, but it cannot restore detail already removed by JPG compression. The converted image keeps the decoded JPG pixels.
Does the PNG become transparent?
No. A JPG has no transparency channel, so conversion does not invent transparent areas. Use the background removal or image editor tool if you need to create transparency deliberately.
Why can the PNG file be larger than the JPG?
PNG stores pixels losslessly, while JPG is designed to compress photographs by discarding some visual information. Detailed photos therefore often become substantially larger as PNG files.
Is my JPG uploaded during conversion?
No. FileGizmo decodes the JPG and creates the PNG in a browser worker on your device. The normal page policy also blocks connections to third-party processing services.
