JPG to PNG Converter
Convert JPEG photos to lossless PNG images — private, in your browser
Move your JPEGs into the lossless PNG format
JPEG is brilliant at squeezing photographs down to a small size, but every time it saves it quietly throws a little detail away. PNG works the opposite way: it keeps every pixel exactly as it is and adds an alpha channel for transparency. Converting a JPG to PNG is the step you take before editing, layering graphics or exporting artwork that needs sharp edges and no compression noise creeping in.
This converter reads your JPEG, redraws it onto a canvas and writes a clean PNG that will not degrade no matter how many times you open and re-save it afterwards. Nothing is uploaded, so even sensitive scans and unreleased designs stay entirely on your own machine.

When PNG is the right choice
Lossless from here on
Once an image is a PNG, every future save is pixel-perfect. That matters when a file will pass through several rounds of edits, because JPEG would compound its losses at each step.
Ready for transparency
PNG carries an alpha channel, so after converting you can knock out a background or drop the image onto any colour without an ugly white box around it.
Crisp text and flat colour
Screenshots, logos and diagrams look far cleaner as PNG. JPEG smears fine lines and solid blocks with halos, while PNG keeps them razor sharp.
Frequently Asked Questions
Are my JPG images uploaded to a server?
No. Every conversion is handled locally by the canvas in your browser, so your JPEG files never leave your device. That makes the tool safe for private snapshots and unpublished work.
Why convert a JPG to PNG?
PNG is lossless and supports transparency, so it is the better container when you plan to edit an image repeatedly, overlay a logo, or need crisp text without the blocky artefacts JPEG can leave behind.
Will the PNG file be larger than the JPG?
Usually yes for photographs, because PNG stores every pixel without discarding data. For screenshots and images with large flat areas the difference is much smaller.
Does converting to PNG improve the picture quality?
It cannot restore detail that JPEG already removed, but it stops any further loss. From the PNG onward every edit and save keeps the pixels exactly as they are.
Can I convert several JPGs at once?
Yes. Drop a whole batch of JPEG files and download them together as a single ZIP of PNG images.
