How to convert PNG to JPG

Four steps to compact JPGs.

Add your PNGs

Drop the files onto the zone or click “Browse files”. Up to 30 images per batch, 40 MB each.
Set the quality

Adjust the quality slider — 85% is a good default for photos.
Convert

Click “Convert to JPG” and let the batch process.
Download

Save images individually, or click “Download all as ZIP” for the whole batch.

What this tool does

PNG is a lossless format: perfect quality, transparency support, and file sizes to match. JPG trades a little quality for dramatically smaller files, which is why so many upload forms, marketplaces and email threads prefer it.

This converter draws each PNG onto a canvas and re-encodes it as a JPG at the quality you choose. Because JPG cannot store transparency, any transparent areas are filled with white first — the same result you would get placing the image on white paper. Dimensions stay identical; only the encoding changes.

Conversion runs entirely in your browser with no upload, so it is fast and your images stay on your device.

Key features

Much smaller files

Photographic PNGs typically shrink to a fraction of their size as JPGs at sensible quality.

Quality control

A slider sets the trade-off between size and sharpness for the whole batch.

Batch conversion

Convert up to 30 PNGs in one run and download them together as a ZIP.

Predictable transparency handling

See-through areas are filled with white — no black-box surprises.

No upload

Images are re-encoded locally by your browser.

Works anywhere

Desktop or mobile, with a responsive, accessible interface.

Supported formats and options

Input: PNG images — up to 40 MB each, 30 per batch.

Output: JPG files at the same pixel dimensions.

Adjustable JPG quality for the whole batch.
Transparency is flattened onto a white background.
Individual downloads or a single ZIP for the batch.

Practical use cases

Meeting JPG-only upload forms — job portals, marketplaces and government sites often reject PNG.
Shrinking screenshots — PNG screenshots are heavy; JPG versions mail and upload far faster.
Photo workflows — convert exported PNGs to JPG before sharing or archiving in bulk.
Website weight loss — replace photographic PNGs with JPGs to speed up pages.

Limitations and notes

JPG does not support transparency. If your PNG needs its see-through background, keep it as PNG or convert to WebP with the Image Format Converter.
JPG is lossy — avoid it for images with fine text or sharp line art at low quality settings, and never re-convert the same file repeatedly.
Converting a flat graphic with few colours may produce a larger JPG than the PNG; check the result sizes.
Dimensions are preserved; use the Image Resizer if you also need different sizes.

Frequently asked questions

Are my images uploaded to a server?

No. Decoding and re-encoding happen on the HTML canvas inside your browser. Your images never leave your device.

What happens to transparent areas?

JPG cannot store transparency, so transparent pixels are placed on a solid white background — the same way most viewers display them.

Will the JPG be smaller than my PNG?

Almost always, especially for photos and screenshots. You control the trade-off with the quality slider.

Can I convert several images at once?

Yes. Add a whole batch and download each result individually or everything at once as a ZIP file.

Will the image dimensions change?

No — the pixel dimensions are preserved exactly unless the tool offers a resize option and you choose one.

Why is my JPG larger than the original PNG?

PNG excels at flat graphics with few colours — logos, icons, diagrams — which JPG handles inefficiently. For photos the opposite holds. If a result came out bigger, keep the PNG or try WebP in the Image Format Converter.

Is JPG or PNG better for screenshots?

It depends on the content. Screenshots full of text and flat UI stay crisper as PNG; screenshots of photos or video shrink dramatically as JPG with little visible loss. Convert one and compare at your intended viewing size.

Will converting reduce the resolution?

No. Width and height in pixels stay exactly the same — only the compression changes. The quality slider affects how faithfully the pixels are stored, not how many there are.
