How It Works

Step-by-step guide to convert JPG, WebP, or JPEG images to PNG format online

Upload Your Images

Select one or more JPG, JPEG, WEBP, or PDF files from your device. You can drop a full batch at once — no account needed, no per-session limits.

Convert Image to PNG

Every image is converted to lossless PNG right in your browser. PNG preserves full pixel quality with no re-compression artifacts, and keeps any transparency that was present in your source file.

Download Your PNG Files

Your PNGs are ready to download in seconds. Nothing is sent to any server — safe for IDs, documents, and personal photos you'd rather keep private.

Frequently Asked Questions

Everything you need to know about image resizing

How do I convert an image to PNG for free?

Click Upload, select your JPG, JPEG, WEBP, or PDF files, and download the converted PNGs. Everything runs directly in your browser — no account, no server uploads, no watermarks, and lossless PNGs in seconds.

Can I convert an image to PNG without losing quality?

PNG uses lossless compression, so converting an image to PNG preserves every pixel exactly — nothing is thrown away. That's why PNG is the right choice when you'll edit and re-save a file repeatedly, or need crisp text and sharp edges.

Which formats can I convert to PNG?

You can convert JPG, JPEG, WEBP, and PDF files to PNG. You can mix formats in the same batch — no need to separate them before uploading.

Can I convert a PDF to PNG?

Yes. Upload a PDF and each page is converted to a separate PNG image. That's handy when you need to share individual slides, extract a diagram, or use a page as a background without needing PDF software.

Are my images private when I convert them to PNG?

All conversion happens entirely inside your browser. Your files never leave your device or reach any external server. That makes it safe to convert sensitive files like ID scans, passport photos, or medical images.

Why convert JPG or WEBP to PNG instead of keeping the original?

PNG uses lossless compression, so no quality is lost when you save or re-save the file. It's the right choice when you need to edit an image multiple times, layer it over a transparent background, or avoid the blocky artifacts that accumulate in heavily re-saved JPGs.

Does PNG support transparency?

PNG supports full alpha-channel transparency. If your source file has transparent areas — for example a WEBP with a cutout background — converting to PNG preserves that transparency correctly. JPG doesn't support transparency at all, so PNG is the standard format when you need it.

Will PNG files be larger than my original JPGs?

Usually, yes. PNG is lossless, so file sizes tend to be larger than equivalent JPGs. You're trading file size for quality and transparency support. If you need a smaller PNG, run the output through the Compress Image tool after converting.

Can I convert JPG, JPEG, WEBP to PNG in bulk?

You can upload and convert up to 12 images at once. All files are processed simultaneously in your browser, so a batch of 12 takes roughly the same time as a single file.

Is there a file size or resolution limit?

There's no enforced file size limit — conversion runs on your own device, so performance depends on your hardware. Very large images (over 20 MP) may take a few extra seconds on older phones.

Do I need to install an app or sign up to use this tool?

There's no app to install and no account required. Open the page in any modern browser on your phone or computer and start converting — it works in Safari, Chrome, Firefox, and Edge.

Is this converter free or is there a paid plan?

The converter is completely free with no hidden tiers. There's no watermark on the output, no daily conversion cap, and no feature locked behind a subscription. Convert as many batches as you need.
