JPG to PNG Converter
Repackage JPG photos as PNG — the format editing tools, asset pipelines, and picky uploaders ask for. The conversion is pixel-exact; what it will not do is invent quality a JPEG already threw away, and this page says so plainly.
Convert JPG files to PNG
Drop .jpg or .jpeg files. Each output PNG is re-decoded and dimension-checked before you can download it.
JPG's job, and where it ends
JPEG has been the photograph's travel format since 1992: cameras write it, everything reads it, and its lossy compression is superbly tuned for the smooth gradients of real-world scenes. Its weakness is repetition — every time software opens and re-saves a JPEG, the compressor runs again and quality erodes a little more. That is precisely the moment PNG earns its place: as a lossless parking spot for an image that is about to be edited, composited, or run through tooling that re-saves files behind your back.
What this conversion genuinely does
The decoder unpacks your JPEG into raw pixels — applying the EXIF orientation flag so portrait phone shots come out upright — and the PNG encoder stores those pixels losslessly. Nothing is resampled, nothing is "enhanced". Two consequences worth knowing before you convert: the PNG will be substantially larger than the JPG (the file row shows you real before/after bytes), and metadata does not survive the trip — EXIF including GPS location is stripped, which protects privacy but also removes camera settings and copyright fields photographers may want. Keep your originals.
No magic, verified anyway
"Convert to PNG for better quality" is a myth this site refuses to repeat: detail a JPEG
discarded at capture time is gone. What we can promise is exactness from here on — and prove
it: every converted file is re-decoded and its dimensions verified before the download button
appears, and a file whose name lies about its format (a .jpg that is secretly WebP)
gets flagged and converted from what it actually is.

Frequently asked questions
Does converting JPG to PNG improve the image quality?
No, and any tool claiming it does is selling something. JPEG compression already discarded fine detail when the file was first saved; PNG faithfully preserves what remains, byte-for-byte on every pixel. What you gain is protection from FURTHER loss in later edits and saves.
Then why convert at all?
Because plenty of workflows demand PNG: sprite pipelines, some print-on-demand uploaders, machine-learning datasets, app-icon and asset tooling, and editors where repeated saves would otherwise recompress a JPEG each time. PNG is the format you park an image in while working on it.
Will the PNG be bigger than my JPG?
Almost always, often 5–10× for photos — the row shows the exact numbers for your file. That is the nature of lossless storage, not a defect of the conversion.
Does the PNG get transparency?
It can carry alpha, but a JPG has none to give: the output is fully opaque. Cutting out a background is an editing job this converter honestly does not do.
My sideways phone photo — will it stay sideways?
No, it comes out upright. Phones often store the pixels rotated plus an EXIF orientation flag; the decoder applies that flag before re-encoding, so the PNG looks the way the photo was shot.
Where does the conversion actually run?
In your browser tab, on your machine. There is no upload endpoint, the security policy blocks cross-origin requests, and the methodology page documents how to watch the (empty) network tab while converting.
Local processing: conversion happens in your browser; your photos never leave your device. Verification steps are on the methodology page.
