What is JPG to PNG?

Convert JPG files to PNG format instantly.

JPG to PNG is part of Smart2Office's suite of free browser-based productivity tools.

Open the page, use the tool, close it — nothing to set up, nothing to maintain, and nothing to pay.

The tool runs on any modern device — Windows PC, Mac, iPhone, Android phone or tablet — directly in your web browser. There is no version to update, no operating system compatibility issue, and no licence to renew.

Frequently Asked Questions

Do you upload my images to a server?
No. Image processing uses the browser's built-in Canvas API. Your images are processed locally and never sent to any server.
Which image formats are supported?
Most tools support JPG, PNG, WebP, GIF, BMP and SVG. The accepted and output formats depend on the specific tool.
Will compression reduce visible quality?
At quality settings above 70%, compression is generally imperceptible. PNG compression is lossless — PNG output is always full quality.
Can I process multiple images at once?
Yes. Tools like Batch Resize and Compress Image accept multiple files. Results are packaged in a ZIP file for one-click download.
What is the maximum resolution supported?
There is no hard limit. Very high-resolution images (above 10,000 × 10,000 pixels) may be slower depending on browser memory.
Why should I convert to WebP?
WebP files are typically 25–35% smaller than equivalent JPG or PNG at the same visual quality — ideal for websites and apps.
🔒 Your Privacy & Security — Your images are processed by the browser's built-in Canvas API. No image data leaves your device — everything happens locally. Smart2Office does not track what you process, does not store output files, and does not share your data with third parties. What you create belongs entirely to you.
