Converting PNG to JPG reduces file size by 60–80% while keeping photos looking sharp. The trade-off: JPG is lossy (slight compression artifacts at high compression) and doesn't support transparency. For photos and complex images, that trade-off is almost always worth it. This guide explains when to convert, when to keep PNG, and how to get the best quality result.

When to Convert PNG to JPG

Photos and complex images: JPG compresses photos much better than PNG. A 2 MB PNG photo typically becomes a 200–400 KB JPG at 85% quality.
Reducing email attachment size: most email clients have 10–25 MB attachment limits. Converting photos to JPG easily brings multiple images under the limit.
Web performance: JPG loads faster. For photos on websites, JPG is the standard format unless you need WebP (which is even smaller).
Sharing on social media or messaging apps: platforms often re-compress images. Starting with JPG at 85–90% quality gives better control over final appearance.

When NOT to Convert PNG to JPG

Logos and graphics with transparency: JPG doesn't support transparent backgrounds. A logo on a transparent PNG will get a white (or black) background after conversion.
Screenshots with text or UI elements: JPG compression creates visible artifacts around sharp edges and text. PNG stays crisper for screen captures.
Images you'll edit again later: JPG loses quality each time you save. Keep working files as PNG and export to JPG for final delivery only.
Images with large flat areas of color: logos, illustrations, and icons compress better as PNG. JPG adds noise to solid colors.

File Size Comparison

Here's what you can typically expect when converting photos from PNG to JPG:

Smartphone photo (12 MP): 8–15 MB PNG → 1.5–3 MB JPG at 90% quality
Web banner (1920×1080): 2–4 MB PNG → 200–600 KB JPG at 80% quality
Product photo (2000×2000): 3–5 MB PNG → 300–800 KB JPG at 85% quality
Screenshot with text: 500 KB PNG → 150–300 KB JPG (artifacts on text)

The actual savings depend on image content. Photos with lots of color variation compress much better than solid-color graphics.

How to Convert PNG to JPG Free

Open the image compressor and upload your PNG file (or drag and drop)
Set quality to 85% for a good balance of size and quality. Use 90–95% for print-quality output; use 70–80% for web thumbnails
Download the JPG — the compressor outputs JPEG format from any input including PNG

For transparency: if your PNG has a transparent background, the compressor fills it with white before converting. If you need a different background color, use the cropper or an image editor to add the background first.

PNG vs JPG — Format Comparison

PNG: lossless compression, supports transparency (alpha channel), larger files, best for logos/icons/screenshots
JPG/JPEG: lossy compression, no transparency, smaller files, best for photos and complex images
WebP: even smaller than JPG, supports transparency, best for web. Convert PNG to WebP with our PNG to WebP converterfor the smallest file size

JPG Quality Settings Explained

JPG quality is a scale from 1–100 that controls the trade-off between file size and image quality:

95–100%: near-lossless, large files — use only for archiving or print
85–90%: high quality, half the size of 100% — standard for photos
75–80%: good quality, small files — standard for web images
60–70%: noticeable compression, very small files — use for thumbnails only
Below 60%: visible artifacts, only for rough previews

For most use cases, 80–85% quality is the sweet spot: files are 5–10× smaller than the original PNG, and compression artifacts are barely visible in photos.

Batch Conversion

To convert multiple PNG files to JPG at once, upload them all at once in the image compressor. It processes each file and lets you download them individually or all at once.

Is the Conversion Reversible?

Not cleanly. Converting JPG back to PNG gives you a PNG file, but the quality lost during JPG compression is permanent — you won't get back the original PNG quality. Always keep your original PNG files if you might need them later. Only convert to JPG when you're done editing.
