JPG to PNG Converter
Convert JPG photos to PNG — a lossless format that's perfect for editing, screenshots, and graphics that need to stay crisp through repeated saves.
Private by design: This tool runs entirely in your browser using its built-in image engine. Your files are not uploaded to a server, and nothing you convert is stored or logged.
How to convert JPG to PNG
Drop your JPG files onto the upload area, or click it to browse.
Click Convert. Each photo is re-encoded as a lossless PNG in your browser.
Download images individually, or grab everything as a ZIP.
Good to know
PNG is lossless: once converted, you can edit and re-save the file without any further quality loss.
PNG files are usually larger than the JPG they came from — that's the trade-off for lossless storage.
Converting to PNG can't restore detail the JPG compression already discarded; it preserves exactly what's in the source photo.
Frequently asked questions
Does JPG to PNG improve image quality?
No — compression artifacts already baked into the JPG stay. What PNG gives you is a lossless container: from this point on, edits and re-saves won't degrade the image any further.
Why is my PNG bigger than the original JPG?
JPG compresses photos aggressively by discarding detail; PNG keeps every pixel. For photographic images PNG files are typically 3–10× larger.
Can I convert several JPGs at once?
Yes — drop in as many as you like. They're converted one after another on your device, and you can download the results as a single ZIP.
Are my photos uploaded anywhere?
No. Conversion happens entirely in your browser — your photos never leave your device.
