What is the JPG to PNG Converter — Free & Private?
JPG to PNG Converter
Convert JPG (JPEG) images to PNG quickly and privately. PNG is lossless, so once your image is a PNG, repeated edits and re-saves won't add more JPG compression artifacts — making it the better choice for editing, screenshots and graphics with crisp edges.
Because every conversion runs through the browser's own canvas engine, your images never leave your device — there is no upload, no queue, and no server that could retain a copy.
Why convert JPG to PNG
- Lossless from here on — no further generation loss when you re-save.
- Sharp edges and text stay clean, unlike heavily compressed JPGs.
- Transparency-ready if you later remove a background in an editor.
Note: PNG stores every pixel exactly, so the file will usually be larger than the original JPG.
How it works
How JPG to PNG Conversion Works
Your JPG is decoded to pixels and re-encoded as a lossless PNG. No quality is added back (the original JPG compression is already baked in), but no new loss is introduced.
Steps
- Drop one or more JPG/JPEG files.
- The output is preset to PNG (lossless — no quality slider needed).
- Click Convert and download.
Behind the scenes
decode(jpeg) -> draw to canvas -> encode("image/png")
Examples

Frequently asked questions
Does converting JPG to PNG improve quality?
Does converting JPG to PNG improve quality?
No — it can't recover detail that JPG compression already discarded. What it does give you is a lossless file, so future edits and saves won't add more compression artifacts.
Why is my PNG larger than the JPG?
Why is my PNG larger than the JPG?
PNG is lossless and stores each pixel exactly, while JPG throws away data to stay small. A larger PNG is expected, especially for photos.
Will my image have transparency?
Will my image have transparency?
The converted PNG keeps whatever the JPG had — and JPGs are fully opaque. PNG simply makes it possible to add transparency later in an image editor.
Is it free and private?
