Image Compressor

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.
