How to Convert JPG to PNG
Upload your JPG and click Convert. The tool decodes the image and re-encodes it as a lossless PNG, showing you both file sizes before you download. The whole conversion takes seconds and never leaves your browser.

Understanding the JPG to PNG Tradeoff
JPG and PNG represent opposite philosophies. JPG was designed for photographs: it discards subtle detail the eye barely notices, achieving dramatic compression, often under 200 KB for a photo that would be several megabytes as PNG. PNG was designed for exactness: every pixel stored perfectly, which is essential for graphics, screenshots with text, and images you plan to edit repeatedly. Converting JPG to PNG moves you from the efficient world to the exact world. The practical benefit is editability: open a JPG, edit, and save as JPG ten times, and artifacts accumulate visibly; convert to PNG first, and subsequent edits stay pristine because PNG never re-quantizes. The cost is file size, which balloons because PNG must losslessly encode the noise-like JPG artifacts along with the real detail. Convert when your workflow demands PNG: print pipelines, design tools, archival edits, or compositing. Keep the JPG when the destination is the web and the image is already final.
Tips
Expect the PNG to be much larger: this is normal, not an error. If you need smaller PNGs, reduce dimensions first with the Image Resizer, since fewer pixels need fewer bytes. For web use after editing, consider converting the finished PNG back to JPG or WebP at quality 85 to 90 for the final published file. And remember that no converter can add transparency to a JPG photo: transparent backgrounds must be created by masking, not by format conversion.
Frequently Asked Questions
Why convert JPG to PNG?
The main reasons are transparency workflows and further editing. PNG is lossless, so once converted, additional edits and saves will not degrade quality further the way repeated JPG saves do. PNG is also required by some print pipelines and design tools. Note that conversion cannot restore detail the JPG already discarded or add transparency.
Will the PNG be larger than the JPG?
Almost always, often 3 to 10 times larger. JPG is a highly efficient lossy format for photos, while PNG stores every pixel exactly. If file size matters more than editability, keep the JPG. Convert when you need PNG format specifically, not to save space.
Does converting improve quality?
No. The PNG preserves the JPG pixels exactly as they are, including any compression artifacts. It prevents further degradation during editing, which is valuable, but it cannot recover lost detail. Think of it as freezing current quality, not enhancing it.
Can I convert multiple JPGs at once?
This tool converts one image at a time for simplicity and reliability. For batch work, convert each file in turn: the process takes only seconds per image since everything runs locally with no upload queue. Each conversion is independent and instant.
Is my image uploaded to a server?
No. Decoding and re-encoding happen in your browser via the Canvas API. Your photos never leave your device, and no signup or payment is ever required. The conversion preserves your exact pixels with zero additional compression. Your original JPG is never modified or overwritten.
