Why convert images to PNG?
PNG is the format you choose when fidelity matters more than file size. It is lossless — the pixels you put in are the pixels you get out, no matter how many times the file is saved — and it supports full transparency, sharp-edged graphics and precise color. Design tools, documentation systems and archives treat PNG as a safe, stable standard.
Typical reasons to convert: a JPG that needs to be annotated repeatedly (screenshots for a report, marked-up photos for feedback) and should not accumulate compression damage; a WebP that must open in older software; an image headed into a layer-based editing workflow where lossless source material is expected. Converting to PNG freezes the current quality and makes every later edit non-destructive.
Understand what conversion cannot do: it does not repair quality already lost in a lossy source. A blurry JPG converts to a PNG with exactly the same blur — lossless means no further loss, not recovery. And PNG files are larger than JPG or WebP for photographic content, sometimes dramatically so; keep PNG for editing and archiving, and convert back to WebP or compressed JPG when publishing.
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, PNG, WEBP. 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.
