How to convert JPG to PNG
- 1
Drop your JPG file into the converter above, or click to browse. Nothing is uploaded — the file stays on your device.
- 2
Adjust the settings (an optional max width). Tip: No quality setting needed — PNG is lossless, so you get an exact copy of the JPG's current pixels. Expect the file to get larger; that's normal for PNG.

Click “Convert to PNG”. The conversion runs locally in your browser — larger files take longer, and a progress bar keeps you posted.

Why convert JPG to PNG?
PNG's key property is that it's lossless from here on: once your JPG is a PNG, you can edit and re-save it endlessly without the cumulative generation loss JPG suffers with every save. That makes PNG the right working format for images headed into an edit pipeline.
Plenty of tools also simply require PNG — design apps, print-on-demand services, app-store asset uploads, and OS icon pipelines among them. This conversion produces a standard PNG accepted by all of them.

About the formats
JPG JPEG (Joint Photographic Experts Group)
JPG is the universal photo format. Its lossy compression shrinks photographs dramatically with little visible quality loss, and every device, website, and app on earth can open it. It doesn't support transparency, and re-saving repeatedly degrades quality.
PNG Portable Network Graphics
PNG is the standard lossless image format: pixels are preserved exactly, and full alpha transparency is supported. That makes it ideal for screenshots, logos, and UI graphics — at the cost of much larger files than lossy formats, especially for photos.
Frequently asked questions
Will converting JPG to PNG improve the image quality?
No — conversion can't restore detail the JPG compression already discarded. What PNG gives you is protection from further loss: all future edits and saves are lossless.
Why is the PNG so much bigger than my JPG?
That's expected: PNG stores pixels losslessly while JPG compresses them aggressively. For photos, the PNG is commonly 5–10× larger — the price of a format that never degrades.
Is this JPG to PNG converter really free?
Yes — completely free, with no watermarks, no sign-up, and no conversion limits. The tool is supported by ads on this page, so the converter itself never asks you for anything.
Are my files uploaded to a server?
No. This converter runs entirely in your browser using WebAssembly (a browser build of FFmpeg). Your JPG file never leaves your device — nothing is uploaded, stored, or seen by us, which also makes it safe for private or confidential files.
Is there a file size limit?
There's no hard limit. Because conversion happens on your own device, the practical ceiling is your browser's memory — files up to a few hundred megabytes work well on most computers. Very large files may be slow or fail on low-memory devices.
Why does the first conversion take a moment to start?
The first time you convert, your browser downloads the conversion engine (about 31 MB) once. It's cached after that, so later conversions start instantly — and they keep working even offline.
