Converting JPEG to PNG turns a compressed, lossy JPEG into a lossless PNG — useful when you need a format that will not degrade further on re-editing or that supports transparency.
Why convert JPEG to PNG?
Every time a JPEG is saved it loses a little quality. Converting to PNG freezes the current pixels losslessly, so further edits do not compound artifacts. Convert JPEG to PNG when editing screenshots, adding transparency, or preparing images for tools that require PNG.
How to Convert JPEG to PNG
Drop your JPEG files into the workspace, or click to browse.
Select PNG as the output format and adjust quality if needed.
Click Process and download your converted PNG files as a ZIP — everything happens locally.
Frequently Asked Questions
Is converting JPEG to PNG free?
Yes, echloe is free to use for up to 15 images per day. No credit card or account required for basic use.
Are my files uploaded to a server?
No. All conversion happens 100% in your browser using WebAssembly. Your images never leave your device — zero server uploads, complete privacy.
Will converting JPEG to PNG improve quality?
No — it cannot recover detail JPEG already discarded. But it prevents further loss on re-saving and gives you a lossless master for editing. The PNG will be larger than the JPEG.
Why is my PNG bigger than the original JPEG?
PNG is lossless, so it stores every pixel exactly, while JPEG threw data away to shrink. For photos, expect the PNG to be several times larger. Use PNG only when you need lossless quality or transparency.
