How to use JPG to PNG Converter
Convert JPEG photographs and graphics to PNG with drag-and-drop, previews and bulk ZIP download without uploading input files.
- Drag JPEG files to the drop zone or choose them using the file picker.
- Press Convert selected JPEGs and review each image’s output dimensions and approximate size.
- Download individual PNG files or a single ZIP if the total batch fits available browser memory.
Worked example
Add several .jpg images, select Convert selected JPEGs, preview the PNG results and download individually or together as ZIP.
How the tool works and its limitations
The browser decodes each JPEG and draws its pixels into a Canvas element, then exports losslessly encoded PNG output. This does not reverse artifacts already present in a lossy JPEG. Some embedded metadata or color profiles may not survive conversion.
Frequently asked questions
Will PNG improve JPEG photo quality?
PNG avoids further JPEG compression but cannot restore details lost in the source JPEG.
Can I convert multiple JPGs?
Yes. Up to 30 files in one browser batch, subject to per-file image size and device memory safeguards.
Are photos uploaded to a server?
No. Source images are decoded into browser memory; results are downloaded locally.
Privacy, compatibility and safety
Computations run locally using browser JavaScript. The tool does not intentionally send input data or uploaded file contents to Solvory’s servers. Modern browser APIs, JavaScript support and available device memory affect compatibility and batch size. Inspect the output before using it for critical professional work.
