Everything This Converter Does

Real control over the trade-off, none of the usual limits.

Live quality slider

Anywhere from 10 to 100, with a re-convert button so you can see exactly what each level costs in file size.

Choose the background

JPEG has no transparency, so pick the colour that replaces it instead of accepting white by default.

Size saving readout

See the reduction per file and across the whole batch, with a visual bar.

Batch conversion

Convert a whole folder of PNGs at once, with no per-file clicking.

ZIP download

Take every converted JPEG in a single archive rather than one at a time.

Resize while converting

Cap the width and images are scaled down with high-quality smoothing in the same pass.

Change settings anytime

Adjust quality or background and reprocess everything without re-adding the files.

Metadata removed

Canvas conversion drops EXIF, including any GPS coordinates stored in the original.

No limits

No file size cap, no daily quota, no watermark and no signup.

Fully private

Images never leave your browser — nothing is transmitted, stored or logged.

How Much Smaller Will It Get?

The saving depends entirely on what the image contains.

Image typeTypical saving
Photograph70-90% smaller
Screenshot with photos50-75% smaller
Illustration with gradients40-70% smaller
Flat logo or iconOften larger
Text screenshotOften larger, and blurry

If the readout shows your file getting bigger, the image is the kind PNG handles better — keep the original.

How to Convert PNG to JPG

PNG stores every pixel exactly, which is wonderful for logos and screenshots and terrible for photographs — a camera image saved as PNG can easily be ten times larger than the same picture as JPEG with no visible difference. That's the usual reason to convert, and this tool gives you the two controls that actually determine the outcome. The quality slider runs the full range from 10 to 100 with a re-convert button, so instead of accepting whatever a fixed default produces, you can try 85, look at the size, try 75, and settle on the point where the file stops shrinking meaningfully. The second control is the background colour, and it exists because JPEG cannot store transparency at all. Every transparent pixel has to become something solid, and nearly every converter silently makes it white — which is fine until your logo was designed for a dark page and arrives with a glaring white box around it. Pick the colour that matches where the image will actually sit. The saving readout shows the reduction per file and across the batch, and it will honestly tell you when a file got bigger, which happens with flat graphics and text screenshots that PNG already handles better. Convert as many files as you like and take them as a single ZIP. Everything runs in your browser, so nothing is uploaded.

PNG vs JPEG

PNG — lossless with transparency

Every pixel is preserved exactly and an alpha channel is supported, which makes PNG ideal for logos, icons, screenshots and anything with sharp edges or text. The cost is file size on photographic content.

JPEG — lossy and compact

Designed for photographs, JPEG discards detail the eye barely notices to achieve much smaller files. It has no transparency and compression is cumulative, so repeated re-saving degrades the image.

Common Use Cases

Shrink photos for the web

A photographic PNG converted to JPEG typically loses 70 to 90% of its size.

Meet upload size limits

Forms, portals and marketplaces often cap attachments at a few megabytes.

Email attachments

Large PNGs can bounce; a JPEG at 85 quality usually fits comfortably.

Faster page loads

Smaller images improve Core Web Vitals on image-heavy pages.

Photo printing services

Most labs expect JPEG rather than PNG.

Free up storage

Batch-convert a folder of photographic PNGs and reclaim most of the space.

Social media

Some platforms re-compress anyway, so uploading a sensible JPEG gives better results.

Strip location data

Conversion removes EXIF, including GPS coordinates, before you share.

Tips & Best Practices

Stay around 85 to 90

Above that you mostly add bytes without visible gain; below it, flat areas and edges start showing artefacts.

Don't convert text screenshots

JPEG artefacts cluster around sharp edges, so text goes fuzzy and the file often grows. Keep those as PNG.

Match the fill to its destination

A white fill behind a logo bound for a dark page produces an obvious pale rectangle.

Keep the PNG original

JPEG compression is cumulative and irreversible, so keep the lossless source for future edits.

Resize before compressing

Halving the dimensions cuts file size far more than lowering quality, and looks better doing it.

Watch the saving readout

If it shows a size increase, this isn't the right conversion for that image.

Troubleshooting

Transparent areas turned white

JPEG has no transparency, so they must be filled. Change the fill colour to match your background and re-convert.

The JPEG is bigger than the PNG

Your image is flat graphics or text, which PNG compresses better. Keep the original.

The image looks blocky

The quality is too low. Raise the slider to 85 or above and press re-convert.

Text became fuzzy

JPEG artefacts concentrate around sharp edges. Text and line art should stay as PNG.

Frequently Asked Questions

How do I convert PNG to JPG for free?

Drop your PNG files above, set the quality, and download each JPEG or the whole batch as a ZIP — free, no signup.

Are my images uploaded to a server?

No. Conversion happens entirely in your browser, so your images never leave your device.

How much smaller will the file be?

For photographs, typically 70 to 90% smaller. Flat graphics may not shrink at all — the readout tells you.

What quality should I use?

Around 85 to 90 for photographs. Higher mostly adds size; lower starts showing visible artefacts.

What happens to transparency?

JPEG can't store it, so transparent pixels are filled with the colour you choose — white by default.

Why did my file get bigger?

PNG compresses flat colour and sharp edges better than JPEG. For logos and text screenshots, keep the PNG.

Does converting lose quality?

Yes, JPEG is lossy. At 85 or above the loss is generally invisible, but it is permanent.

Can I convert several files at once?

Yes. Add as many as you like and download them all as a single ZIP.

Can I change the quality afterwards?

Yes. Adjust the slider and press re-convert to reprocess everything without adding files again.

Is there a file size limit?

No. Nothing is uploaded, so the only constraint is your device's memory.

Is there a daily limit?

No. Convert as many images as you want, as often as you want.

Can I resize while converting?

Yes. Set a maximum width and wider images are scaled down with high-quality smoothing.

Does it remove EXIF data?

Yes. Canvas-based conversion drops metadata, including any GPS coordinates in the original.

Should I convert to WebP instead?

WebP gives smaller files than JPEG at the same quality and supports transparency, but fewer applications can open it.

Can I convert JPG back to PNG?

Yes, but the quality already lost in JPEG compression can't be recovered — the PNG just stores the compressed result losslessly.

Does it add a watermark?

No. The output contains only your image.

Does it work on phones?

Yes, in any modern browser on Windows, Mac, Android or iPhone with nothing to install.

Is this converter really free?

Completely free, forever — no account, no ads and no premium wall.
