Convert JPG to PNG

Convert JPG photos to lossless PNG for editing pipelines and uploads that require PNG — free, instant, nothing uploaded.

Converts to PNG automatically

Your image never leaves your browser — conversion happens on your device.

Drop a JPG and get a lossless PNG back instantly — no upload, no signup, no quality lost in the conversion. The honest version of this tool’s pitch: PNG won’t make a JPG better, but it will stop it getting worse.

How to convert JPG to PNG

  1. Drop your JPG in the box — conversion starts immediately.
  2. Preview the result and check the new size.
  3. Download your PNG.

What this conversion does — and honestly doesn’t — do

A JPG was compressed lossily the day it was saved: some fine detail is gone for good. Converting to PNG faithfully preserves everything that’s left, byte-for-byte lossless from this point on. What it cannot do is resurrect discarded detail or sharpen compression artifacts. If a converter promises “enhanced quality,” it’s selling you the placebo. What PNG genuinely buys you is protection from future loss.

The re-editing problem PNG solves

Every time a JPG is opened, edited, and saved as JPG again, it’s re-compressed — and the artifacts compound. Crop it Monday, adjust it Tuesday, annotate it Wednesday, and by Friday the sky is banding. Converting to PNG before an editing session means every intermediate save is perfect; you only take a compression hit once, at the final export. That’s the workflow professionals use, and it’s the best reason this tool exists. (Crop right here with the crop tool — it can output PNG directly.)

The other reason: systems that insist

Plenty of uploaders simply require PNG: app store assets, print-on-demand portals, government forms, CMS logo slots, documentation systems. The requirement is rarely about quality — it’s about predictable handling. Either way, arguing with a form validator is not a good use of an afternoon.

Details worth knowing

Expect the file to grow — often several-fold, because lossless photo storage is expensive (see the FAQ). The conversion won’t create transparency; JPGs don’t have any to preserve. Dimensions are untouched, and EXIF metadata (location, camera) is dropped, which is usually what you want when sharing. Going the other way for size reasons? That’s PNG to JPG.

Private by design

Decoding and re-encoding run in a background thread on your device. No server sees your photos — which is exactly how converting family pictures and ID scans should work.

Frequently asked questions

Does converting to PNG improve my image quality?
No — and any tool implying otherwise is misleading you. JPG compression already discarded some detail when the file was saved; converting to PNG preserves exactly what remains, losslessly, but cannot restore what was thrown away.
Why is the PNG so much bigger than my JPG?
PNG stores the image losslessly, and photographs have the kind of pixel variety that lossless compression can't shrink much. A 2 MB JPG photo commonly becomes an 8–15 MB PNG. That's normal and expected.
Will my PNG have a transparent background?
No. JPG images have no transparency to preserve — the PNG will look identical, background included. Making a background transparent requires an editor or background-removal tool, not a format conversion.
So when is this conversion actually useful?
When a system demands it (upload forms, print portals, app stores requiring PNG assets), and when you're about to edit: every re-save of a JPG loses a little more quality, while PNG can be edited and saved repeatedly with zero further loss.
Is my photo uploaded anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted or stored.
