How it works

Re-encode a JPEG as a lossless PNG in your browser. Useful when a tool or workflow demands PNG input.

Honest framing first: converting JPG to PNG doesn't recover quality. JPEG compression already discarded detail, and PNG faithfully preserves whatever is left — including the artefacts. Expect the PNG to be noticeably larger than the JPEG, often 3-10x, because PNG is lossless. So why convert? Some tools only accept PNG (app stores, certain CMSes, design software), PNG survives repeated editing without accumulating more compression damage, and PNG is the right container if you're about to add transparency in an editor. The conversion runs on a canvas in your browser, so nothing is uploaded — fine for private photos and documents. Drop the JPG, hit convert, and download the .png with the original filename.

Frequently asked questions

Will converting to PNG improve the image quality?

No. The JPEG's compression loss is permanent. PNG just stops any further loss from happening in later edits or re-saves.

Why is the PNG so much bigger than my JPG?

PNG is lossless, so it stores far more data per pixel than JPEG's lossy compression. 3-10x larger is normal for photos.

When should I convert JPG to PNG?

When a tool requires PNG input, when you'll edit the image repeatedly, or when you're about to add transparency in an editor.

Is my photo uploaded?

No. The conversion runs entirely in your browser on a canvas. The file never leaves your device.
