JPG to PNG Converter - Free Online Batch Image Converter

Q: Is this JPG to PNG converter free?

Yes, completely. There is no sign-up, no watermark and no limit on how many images you convert.

Q: Will converting to PNG improve the quality?

It will not add back detail that JPG already discarded, but it stops any further loss. The PNG is a perfect, lossless copy of the JPG as it currently looks, ideal as an editing master.

Q: Can I convert many JPGs at once?

Yes. Drop in up to 30 files and they are all converted together; then download them individually or all at once.

Q: Does it keep transparency?

JPG files never contain transparency, so there is none to keep here, but the PNG you get fully supports an alpha channel if you add transparency later in an editor.

About the JPG to PNG Converter

Why convert JPG to PNG?

JPG (or JPEG) is the format of choice for photographs: it squeezes files down to a fraction of their size, but it does so by throwing away detail — that's why re-saving a JPG over and over slowly turns it into a smeary mess. PNG is different. It's lossless, so every pixel is kept exactly, and it supports true transparency. Converting a JPG to PNG gives you a clean copy you can edit, layer, or annotate without piling on more compression damage.

This converter runs entirely in your browser. Drop in one file or thirty, and each is redrawn onto a canvas and re-encoded as a PNG on your own machine — nothing is ever uploaded, so even private photos stay private.

How to Use This Tool

Add your images. Click to upload, drag & drop, or paste — you can queue up to 30 JPGs at once.
Let it convert. Each file is converted to PNG automatically the moment it's added.
Resize if you want. Set a width in pixels to scale every image down (or up); leave it blank to keep the original size.
Download. Grab files one at a time, or hit Download all to save the whole batch.

JPG vs PNG at a glance

Compression: JPG is lossy (smaller files, some quality loss); PNG is lossless (larger files, perfect pixels).
Transparency: JPG has none; PNG supports a full alpha channel.
Best for: JPG suits photographs; PNG suits logos, screenshots, line art and anything you'll edit.
File size: A PNG made from a photo is usually bigger than the JPG — that's the trade-off for going lossless.

Common Use Cases

Editing: Get a lossless base before retouching, so you don't compound JPG artifacts.
Screenshots & graphics: Convert JPG screenshots to crisp PNGs for docs and slides.
Tools that need PNG: Some apps and uploaders only accept PNG — this makes the switch in seconds.

Prefer a smaller, modern format? Try JPG to WebP. Going the other direction? Use WebP to PNG, or duplicate an image into a grid with the Image Duplicator.
