Why convert JPG to PNG?
JPG is built for photographs: small files, lossy compression. But its compression artifacts become a problem the moment a file enters an editing workflow. Every time you edit and re-save a JPG, the lossy compression compounds — colors shift, edges soften, and after a few rounds the degradation is visible. Converting to PNG first freezes the current quality: PNG is lossless, so editing, annotating and re-saving costs nothing further.
PNG also serves purposes JPG cannot. Screenshots with sharp text, diagrams, logos and images that need a transparent background all belong in PNG, where crisp lines stay crisp and alpha channels survive. If you are annotating a photo with text callouts for documentation or a report, converting to PNG first keeps the added text perfectly sharp even though the photo underneath stays as-is.
Be aware that converting JPG to PNG does not restore quality already lost — the artifacts baked into the JPG carry over pixel-for-pixel. What you gain is that no further loss occurs in subsequent editing. Also expect the PNG to be considerably larger, since lossless encoding has no free lunch.
PNG vs. other formats: quick comparison
PNG uses lossless compression: decoded pixels match the source exactly. It supports alpha transparency, making it the standard for graphics that must sit on any background. Its weakness is size — photographic content in PNG routinely runs several times larger than the same image in JPG or WebP.
Compared with JPG: PNG never degrades across edits and handles sharp edges (text, lines, UI screenshots) without artifacts, but pays for it in file size. Compared with WebP: WebP's lossless mode is 20–30% smaller and its quality mode far smaller still, with transparency support in both — but PNG is more universally accepted by editing software and older systems.
Choose PNG when quality must be preserved exactly, when the image contains sharp text or needs transparency, or when the file will be edited further. For web delivery, convert the final result to WebP; for photos, JPG remains the efficient choice.
Private by design: conversion without upload
This converter does not send your image anywhere. Decoding and encoding both run inside your browser using the same image pipeline your browser uses to display pictures — there is no server involved, no queue, and no copy of your file on any machine but yours. When you close the tab, everything is gone.
That matters more than it sounds. Server-based converters require uploading the full original to someone else's infrastructure, where retention policies are invisible and breaches are possible. For product photos, ID scans, contracts photographed as images or anything confidential, browser-side conversion is the only design that keeps the risk at zero.
Speed is a pleasant side effect: without the upload-download round trip, a PNG conversion typically completes in well under a second per image on a modern device, and batch-dropped files process in parallel. The same privacy guarantee holds for every tool on this site.
Frequently asked questions
Is this converter really free?
Yes — unlimited conversions, no signup, no watermark, no hidden limits.
Are my images uploaded to a server?
No. Conversion runs entirely inside your browser. Your files never leave your device, which is what makes this tool safe for confidential images.
Which formats can I convert to PNG?
This page accepts JPG. The output is always PNG.
Can I convert multiple images at once?
Yes — drop several files at once and download each converted image individually.
Does it work on mobile?
Yes, it works in modern mobile browsers including Safari on iOS and Chrome on Android.
Is there a quality loss?
PNG output is lossless. JPG and WebP output use high-quality encoding (92%) that is visually indistinguishable from the original at normal viewing sizes.
