Need a PNG instead of a JPG? This free converter turns your JPG files into PNG right in your browser — no uploads, no account, and no software to install. Everything below explains how it works, what changes when you convert, and how to get the best result.
How to convert JPG to PNG
- Add your JPG files above — drag and drop, click to browse, or paste. Nothing is uploaded.
- Each file is decoded and re-encoded to PNG on your device, right in the browser.
- Download each PNG individually, or grab the whole batch as a single ZIP.
Why convert JPG to PNG?
JPG is a good fit for sharing photos and web images, but it isn’t always the right choice when you need to share, upload, edit, or archive an image. Converting to PNG gives you a file that’s better suited to those jobs.
What you gain with PNG:
- Lossless quality
- Transparency support
- Universal compatibility
Because PNG is lossless, the converted files are often larger than the JPG originals — that’s the trade-off for perfect fidelity.

| Transparency | No | Yes |
| Animation | No | No |
| Best for | Sharing photos and web images | Graphics, screenshots, logos, and editing |
What is JPEG (.jpg)?
JPG (also written JPEG) is the universal photo format, standardized back in 1992. It is the default for digital cameras, the web, and virtually every device and app made in the last three decades.
JPEG uses discrete cosine transform (DCT) compression, dividing the image into 8×8 pixel blocks and discarding the fine detail your eye is least likely to miss. It is lossy and limited to 8 bits per channel, with every pixel opaque — no transparency.
What is Portable Network Graphics (.png)?
PNG (Portable Network Graphics) is a lossless format built for the web and for graphics work. It records every pixel exactly, supports clean transparency, and opens everywhere JPG does.
PNG uses DEFLATE, a lossless compression algorithm, so re-saving never degrades the image. It supports a full 8-bit alpha channel for smooth transparency and up to 24-bit color, which is why it is the go-to for anything with sharp edges or text.
When PNG is the right choice
PNG is a strong pick for:
- Logos, icons, and graphics
- Screenshots
- Images that need transparency
- Editing and long-term archiving
Quality and file size
PNG is lossless, so it reproduces the decoded image pixel-for-pixel with no compression artifacts. That fidelity is ideal for graphics, text, and archiving. Because PNG is lossless, the converted files are often larger than the JPG originals — that’s the trade-off for perfect fidelity. Need a specific file size instead? Try our compress-image tool.
Is it private?
Yes. Everything runs locally in your browser, so your JPG files are never intentionally sent to a server. Read more on our privacy page, or see whether converting images online is safe.
Frequently asked questions
Is this JPG to PNG converter free?
Yes. It’s completely free with no signup, no watermarks, and no per-file limits beyond sensible batch caps that keep your browser responsive.
Are my JPG files uploaded to a server?
No. Conversion happens entirely in your browser using WebAssembly and your device’s own image tools, so your files are never intentionally sent to a server.
Does converting JPG to PNG reduce quality?
PNG is a lossless format, so every pixel from the decoded image is preserved exactly — there’s no visible quality loss.
Will converting to PNG keep transparency?
PNG supports transparency, but JPG images are fully opaque to begin with — so there’s nothing to lose, and your converted files stay opaque.
Can I convert multiple JPG files at once?
Yes. Add up to 50 files per batch, convert them together, and download them individually or as a single ZIP.
Does the JPG to PNG converter work on a phone?
Yes. It runs in any modern browser — Chrome, Edge, Firefox, and Safari — on Windows, macOS, Android, and iPhone or iPad. Because it works on-device, you can convert straight from your phone’s photo library.
Is there a file size limit?
You can convert files up to 100 MB each. Because everything runs in your browser, very large files depend on your device’s available memory.
