Convert PNG to JPG

PNG is lossless: it stores every pixel exactly, which is perfect for screenshots and graphics but wasteful for photos. A photo saved as PNG can easily be 3–10 times larger than the same photo as JPG.

Convert PNG to JPG when:

• an upload form only accepts JPG or has a tight size limit,
• you want to email photos without hitting attachment limits,
• your website images load slowly,
• you are running out of storage because of large PNG photos.

Everything runs in your browser; your images are not uploaded to any server.

• File size drops, often dramatically for photos.
• Transparency is replaced with white. JPG has no alpha channel, so transparent areas get a white background.
• Slight quality loss. JPG is lossy. At 85–90% quality you will not see it in photos, but sharp text and thin lines can get faint halos.
• Dimensions stay the same. The image keeps its exact pixel size.

Image type	Better format
Photos, scanned pictures	JPG
Screenshots with text	PNG
Logos, icons, diagrams	PNG (or SVG)
Images with transparency	PNG or WebP

The quality slider runs from 30% to 100%:

• 90–100%: maximum quality, larger files. Good for printing.
• 75–85%: the best balance for web, email and social media.
• Below 70%: smaller still, with visible artifacts around edges.

You can preview the result by opening the downloaded file. If you see soft halos around text or edges, convert again with a higher setting.

If you need the JPG to be under a specific size, such as 200 KB for an online application, use the image compressor in target-size mode. It finds the highest quality that fits automatically.

You can drop dozens of PNG files at once. Each one is converted in turn, the list shows what is queued, and the results download together as a single ZIP file, keeping the original file names with a .jpg extension.

This is handy when you export slides or design frames as PNG and need them as JPG for a website, or when a camera, scanner or screen recorder saved a whole folder of PNG files that take up too much space. Converting a set of large PNG photos to JPG at 85% quality often frees up most of the space they used.

Because everything happens in your browser, the speed depends on your device. A modern laptop converts a typical photo in well under a second, and phones are only a little slower.

Screenshots of text, spreadsheets and user interfaces compress very efficiently as PNG and often look worse as JPG, with fuzzy edges around letters. Before converting, compare the file sizes: if the JPG is not much smaller, keep the PNG.

For logos and icons with transparent backgrounds, consider PNG to WebP, which keeps transparency and still makes the file smaller. Going the other way, JPG to PNG is useful when a program requires PNG.
