JPG to PNG
Convert JPG to lossless PNG with transparency preserved. Free, browser-based, no upload.
Convert JPG to PNG entirely in your browser. The file is decoded and re-encoded on your own device using the browser's built-in image engine, so it is never uploaded to a server — useful for private screenshots, ID scans, or client work you would rather not send anywhere. There is no signup, no watermark, and no file-size limit beyond your device's memory.
JPG is the universal photo format — small files, opens everywhere, no transparency. PNG is lossless and supports transparency — best for graphics, logos, and screenshots.

About JPG to PNG
Convert JPG photos to lossless PNG — useful when a tool or platform requires PNG, or before editing where you want no further compression artifacts. Conversion runs in your browser.
How to use the JPG to PNG
- 1
Add your JPG file
Drag your JPG image onto the tool or click to browse. It loads locally in your browser; nothing is sent to a server.
- 2
Convert to PNG
Click Convert. PNG is lossless, so there is nothing to configure — the output keeps every pixel of the original.
- 3
Check the result
Compare the new PNG file size against the original JPG. Re-run at a different setting if you want to trade a little quality for a smaller file.
- 4
Download
Save the PNG to your device. Your original JPG is untouched, so you can always convert again with different settings.
JPG vs PNG: what changes
JPG: JPG is the universal photo format — small files, opens everywhere, no transparency.
PNG: PNG is lossless and supports transparency — best for graphics, logos, and screenshots.
PNG is lossless, so the converted file matches the source pixel-for-pixel — there is no quality slider and nothing is discarded.
Why convert in your browser
Most online converters upload your image to a remote server, process it there, and send it back — which means your file sits on someone else's machine. This tool runs the whole conversion locally in your browser tab, so the image never leaves your device. There is no upload wait, no per-file size cap, and sensitive images stay private. Once the page has loaded, it even works offline.
Quick tips
- ✓Keep your original JPG. Converting does not delete it, and you may want to re-export at a different quality later.
- ✓Converting a photo to PNG will not shrink it — PNG is lossless and best for graphics, logos, and screenshots. For a smaller photo, convert to JPG or WebP instead.
- ✓PNG is a good fit when you need transparency or pixel-perfect graphics.
- ✓Converting does not change the pixel dimensions — only the format and file size. Use a resize tool first if you also need the image smaller.
- ✓Browser-based conversion usually strips EXIF metadata like GPS and camera info, which is often a privacy plus when sharing photos.
Frequently asked questions
Does converting JPG to PNG improve quality?
No. PNG can't recover detail JPEG already discarded — it just stops adding new compression loss going forward.
Why would I convert to PNG?
For tools that require PNG, for lossless editing, or to add transparency afterward.
Will the PNG be larger?
Usually yes — PNG is lossless, so photographic content produces a bigger file than the JPG.
