How to Convert JPG to PNG
- 1
Drag one or more JPG or JPEG images into the box above, or click to browse and select files — batches convert together.
- 2
Your browser decodes each JPG and re-encodes it as a lossless PNG using the Canvas API — all inside this tab, nothing uploaded anywhere.
- 3
Download each PNG individually, or click Download All for the whole batch.
Why Convert JPG to PNG
JPG uses lossy compression that works brilliantly for photos but falls apart for images with sharp edges, text, logos, or solid blocks of colour — every time a JPG is saved, a little more detail is discarded. PNG uses lossless compression, meaning every pixel is stored exactly as-is, which is why it's the standard format for screenshots, icons, web graphics, and any image you plan to edit further.
The other key advantage of PNG over JPG is transparency. JPG has no alpha channel — every pixel is fully opaque, which means transparent areas show up as white or grey boxes when placed on a different background. PNG supports full transparency, so converting a JPG to PNG is the essential first step when you need to add a transparent background in a photo editor.
Because the conversion happens entirely in your browser tab using the Canvas API, your files are never uploaded to a server — the JPG is decoded and the PNG is created on your own device and handed straight to your downloads folder.
JPG vs PNG: Format Comparison
| Feature | JPG | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | No | Yes (full alpha channel) |
| Best For | Photos, sharing | Graphics, screenshots, editing |
| File Size | Smaller | Larger |
| Image Quality | Some loss per save | Exact pixels preserved |
| Browser Support | Universal | Universal |
| Editing Support | Universal | Universal |
| Free to Use | Yes | Yes |
PNG is the right choice when pixel-perfect quality, transparency, or repeated editing matters. JPG is better for sharing photos where file size is the priority.

Frequently Asked Questions
Why convert JPG to PNG?
PNG is lossless, so it preserves every pixel without the quality degradation that accumulates each time a JPG is re-saved. It also supports transparency, which JPG doesn't — making PNG the right choice for logos, graphics, and images you plan to edit further.
Does converting JPG to PNG improve quality?
Converting to PNG stops further quality loss — PNG's lossless compression preserves the pixels exactly as they are in the JPG. It won't recover detail already lost by previous JPG compression, but it prevents any additional degradation.
Will the PNG be larger than the JPG?
Yes. PNG uses lossless compression which produces larger files than JPG's lossy compression, especially for photos. The trade-off is exact pixel preservation and transparency support.
Is my file uploaded to a server?
No. Everything runs in your browser tab using the Canvas API. Your JPG is decoded and the PNG is created on your own device — nothing is uploaded, stored, or logged anywhere.
Does this work on iPhone and Android?
Yes. The converter runs in your mobile browser using the same canvas-based approach as desktop, so it works on any device with a modern browser — no app required.
