Is it private and safe to use?

Yes. Convert JPG to PNG, online and free runs entirely in your browser — your files are processed on your device and are never uploaded to a server, so no one else can see them. It is free, needs no sign-up, and works offline.

Will converting to PNG improve my photo's quality?

No. The JPG is already lossy, and PNG can only preserve exactly what's there — it can't recover detail the JPG discarded. PNG simply avoids adding any further compression.

Why is the PNG bigger than my JPG?

PNG is lossless, so photos (which JPG compresses efficiently) become much larger as PNG. That's expected. Use PNG when you need lossless output or a tool requires it; otherwise JPG or WebP are smaller.

Can I convert several JPGs at once?

Yes, up to the batch limit. Each is converted in your browser and can be downloaded individually or all together.

Convert JPG to PNG, online and free

Convert a JPG or JPEG photo to PNG entirely in your browser — nothing is uploaded. PNG is lossless and supported everywhere, which helps when a tool or form specifically asks for a PNG. Note that a PNG of a photo is normally larger than the original JPG.

Quick answer

Convert JPG to PNG, online and free is a free browser tool that changes an image from one file format to another. It accepts JPG images, produces PNG images, and handles up to 5 files in one batch. Processing happens locally in this browser; source files are not uploaded to Pixo. No account or software installation is required.

How it works

01
Drop your JPG
Choose one or more JPG/JPEG images. They're read from your device and never uploaded to a server.
02
Pixo converts to PNG
Each image is re-encoded as a PNG in your browser. Since the source JPG is already lossy, the PNG preserves the current pixels — it doesn't restore detail or add transparency.
03
Download your PNGs
Download each PNG, or grab them all at once. The format is PNG; the pixels match your JPG.

Tips for better results

PNG is lossless, so it won't add compression artifacts — but a PNG of a photo is usually larger than the JPG. For smaller photos, keep JPG or use WebP.
Converting JPG to PNG does not create transparency; a JPG has none to begin with. PNG transparency only exists if the source already had an alpha channel.
Everything runs in your browser, so your images stay private and never touch a server.

When to use this tool

Use Convert JPG to PNG, online and free when a browser, app, publishing system, or recipient needs a different image format from the source. Check the result before saving or sharing it so the output matches the destination’s practical, technical, and privacy requirements.
