About this tool
The .jpeg and .jpg extensions describe the same file format; they only differ because early Windows systems limited extensions to three letters. Whichever spelling your camera, phone, or download used, this converter reads the JPEG bytes and writes out a PNG. PNG is a lossless raster format, which makes it a good choice when a photo is going into repeated editing or a workflow that expects PNG. The catch is size: because PNG keeps every pixel untouched, the exported file is usually noticeably larger than the JPEG you started with.
FAQ
No. The extensions .jpeg and .jpg refer to the same file format and are handled identically.
No. It preserves the current pixels without adding new detail.
Nowhere. The conversion happens in your browser using on-device processing.
Around 25MB per file, which suits most photo exports.
More about this tool
How it works
- Select a .jpeg file (or drag it onto the drop area).
- The browser decodes the JPEG and encodes the pixels into PNG without further quality loss.
- Save the resulting PNG to your device.
Features
- Same format, different name — .jpeg files behave identically to .jpg files — no conversion trick is applied to the extension itself.
- Preserve source resolution — The PNG keeps the JPEG's pixel dimensions; there is no automatic downscaling.
- No transparency added — JPEG has no alpha channel, so the PNG background matches the original photo.
- Local processing only — Your photo stays on-device throughout the conversion.
- Single file per run — Convert one JPEG at a time, up to roughly 25MB.
Supported formats
Input: JPEG (.jpeg/.jpg). Output: PNG.
Input
-
JPEG jpeg, jpg
Output
-
PNG png
Common uses
- Fixing extension requirements — Convert when a system rejects .jpeg or a JPEG-encoded file and demands PNG.
- Standardising a photo library — Move mixed .jpg/.jpeg exports into a consistent PNG working set.
- Feeding design tools — PNG plays more cleanly with layered editing than heavily compressed JPEGs.
Limitations
- Output PNGs are usually larger than the input JPEG.
- No transparency is created — JPEG never stored one to begin with.
- Compression artifacts baked into the JPEG carry over.
- One file per conversion, capped near 25MB.
