JPG to PNG Converter
Convert JPG to PNG when you need a lossless source for editing, or transparency support for your output.
PNG is the right format when you need to edit a JPG further (each subsequent save of a JPG compounds compression artefacts), when you want to add transparency, or when you're uploading to a platform that prefers PNG. The conversion itself doesn't recover the data JPG lost — but it stops further losses from accumulating.
This tool runs in your browser. Output files will be larger than the source JPG, sometimes considerably — PNG's lossless format is the trade-off for the editing-and-transparency benefits.

Frequently asked questions
- Why convert JPG to PNG?
- Two main reasons: editing (every JPG save re-compresses; PNG is lossless, so subsequent edits don't degrade), and transparency (PNG supports it, JPG doesn't). For straight-up sharing of photographic content, leaving the file as JPG is usually the better choice — PNG will be larger.
- Will the PNG be bigger than the JPG?
- Yes, usually significantly so — PNG stores every pixel exactly while JPG uses perceptual compression. A 1 MB JPG might become a 4–6 MB PNG. The size penalty is the price of switching to a lossless format.
- Does this restore the original quality?
- No. JPG compression discards information that no tool can recover — converting to PNG just stops further losses from accumulating with each save. The pixels in the PNG are exactly what the JPG decoded to.
- Is my file uploaded?
- No. The JPG is decoded and re-encoded as PNG entirely in your browser. Nothing leaves your device.
- Can I add transparency afterwards?
- Yes — the resulting PNG file format supports transparency, but the converted pixels are still opaque. Use a graphics editor to mask or erase regions you want transparent.
