Files never leave your device — conversion runs 100% in your browser.
Convert JPG to PNG by dropping your file into Imgvert, waiting for the browser to process it, and downloading the finished PNG file. The converter is free, supports batch jobs, and is designed for private local processing: no upload, runs in your browser. That makes it useful for quick format fixes at work, school, or on a shared machine where you do not want image files copied to a remote server.
How to convert JPG to PNG
- Drop your JPG file on the upload area, or choose it from your device.
- Add more files if you want a batch conversion. The queue can process several images in one run.
- Conversion runs in your browser. The file is decoded and written as PNG locally, without an upload to Imgvert. The output keeps the source image's pixel dimensions.
- Download the PNG file, or download the full batch when every item is ready.
Why convert JPG to PNG
JPG is best for compressed photos, but PNG is often easier to use in design tools, screenshots, UI mockups, and workflows that expect a lossless raster format. Converting JPG to PNG can prevent additional JPG compression when you keep editing the file. It can also help when an app asks specifically for PNG. The output will usually be larger than the JPG, and it will not create real transparency where none existed. If you actually need a smaller web file, JPG to WebP is usually a better target.
Use JPG to PNG when the next step is editing, annotation, compositing, or uploading to a system that prefers PNG. For the reverse compatibility step, use PNG to JPG instead.
Because the work happens in the browser, speed depends on your device and the size of the images. Small web graphics usually finish quickly. Large photos, scans, or animation frames can take longer, especially when you drop many files at once. If a batch feels too heavy, split it into smaller groups and download each group before starting the next one.
JPG to PNG FAQ
Use the FAQ below for the practical details people usually need before converting JPG files to PNG: privacy, batch handling, transparency or quality tradeoffs, and when this output format is the right choice. The short version is simple: if the target app asks for PNG, convert locally here and keep your original JPG file as the source copy.
Frequently asked questions
How do I convert JPG to PNG?
Drop the JPG file into the converter and download a PNG after local browser processing. The file stays on your device during conversion.
Does JPG to PNG make the image transparent?
No. PNG supports transparency, but converting a normal JPG does not automatically remove the background. It keeps the visible pixels from the source image.
Will JPG to PNG improve quality?
It prevents another round of JPG compression, but it cannot restore detail already lost in the JPG. The PNG may be larger because it stores pixels differently.
Can I convert JPG images to PNG in bulk?
Yes. Drop several JPG files and download the PNG results after the batch finishes.
Is JPG to PNG private?
Yes. The conversion runs in your browser, with no upload to Imgvert servers.

Limits and privacy
- Files are processed locally in this browser; they are not uploaded to Imgvert.
- This flow renders a still image and does not guarantee preservation of EXIF, ICC, HDR, depth, auxiliary images, animation, or multi-page data.
- PNG output can be larger than a lossy photo format; this converter does not promise a smaller file.
