How to convert JPG to PNG

01 / STEPS

01Add JPG images — Drop JPG files onto the workspace or click to browse. They are read locally in your browser, so nothing is uploaded.
02Set a width (optional) — Enter a target width in pixels to scale the image, or leave it blank to keep the original size.
03Convert and save — Click [ CONVERT ]. When it finishes, compare the original and new sizes, then save each image or download them all.

Features

02 / FEATURES

Local conversion

Each JPG is decoded and re-encoded as PNG in your browser. Nothing is uploaded.

Lossless output

PNG keeps every pixel and can hold transparency, which JPG cannot.

Resize on the fly

Enter a target width and the height scales automatically, or keep the original size.

Why convert JPG to PNG

03 / GUIDE

JPG shrinks photos with lossy compression, which is fine for sharing but costs detail and forbids transparency. PNG keeps the pixels exactly as they are and supports an alpha channel, which makes it the right choice for graphics, screenshots, logos and anything you plan to layer or edit later. Converting to PNG trades file size for a clean, lossless master you can rework without compounding compression artifacts.

What changes in the conversion

04 / DETAILS

›Compression — The PNG is lossless for this step, so no extra detail is lost during conversion. The original JPG artifacts remain, because PNG cannot recreate what the JPG discarded.
›Transparency — PNG can store transparency, but a JPG source has no transparent pixels, so the result stays fully opaque. No background colour is needed.
›Metadata — Re-encoding generally drops the original EXIF and colour profiles, so the PNG is a fresh, simplified copy.

Troubleshooting

05 / GUIDE

If a file will not convert, check that it really is a JPG — other formats are skipped. The PNG is normally larger than the source JPG; that is expected for a lossless format, not a problem. Entering a target width scales the height proportionally, so a single width value is enough.

Frequently asked questions

06 / FAQ

Are my images uploaded anywhere?

No. All decoding and conversion happens in your browser tab. The files are never sent to a server.

Does converting make the image sharper?

No. PNG is lossless, so the copy is as detailed as the JPG you started with — no more and no less. Converting cannot recover detail that was already lost when the JPG was saved.

Will the PNG be smaller than the JPG?

Rarely. JPG is already compressed for photos, while PNG stores pixels without loss, so the PNG is usually larger. Convert to PNG when you need lossless quality or transparency, not a smaller file.

Can I add transparency by converting to PNG?

No. A JPG has no transparent pixels to begin with, so the PNG will be fully opaque. To create transparency you would need to edit the image separately.

Can I resize the image at the same time?

Yes. Enter a target width in pixels and the height scales to keep the aspect ratio. Leave it empty to keep the original size.
