Convert PNG to JPG Online

PNG stores every pixel exactly. That is ideal for logos and interface graphics, but it makes photographs and busy screenshots very large. A phone photo or a full-screen capture saved as PNG can easily be several megabytes, which is slow to email, awkward to attach and often too big for upload limits.

JPG is a lossy format built for photographs. It discards detail that is hard to see, so the same photo is usually much smaller as JPG. It is also the most widely accepted photo format: many application forms, marketplaces, print services and older programs accept JPG even when they reject PNG.

This page is set up to output JPG. Upload a PNG, choose a quality or a target size, and download a .jpg file. If you would rather keep PNG and just make it smaller, try the PNG compressor.

Transparent backgrounds become white

JPG has no alpha channel, so it cannot store transparency. When you convert, fully transparent pixels are filled with white, and partially transparent edges such as soft shadows or smoothed outlines are blended onto white. A logo that looked fine on a dark page will now sit in a white rectangle.

To check whether your PNG has transparency, open it in an image viewer or editor. Transparent areas are usually shown as a grey and white checkerboard. If you need to keep them, convert with the PNG to WebP converter instead, which keeps transparency.

Choosing quality for photos and screenshots

Photos hide compression well, so a quality around 80–85% is a sensible starting point. Screenshots with small text, sharp lines and flat colours show JPG artefacts more easily, as faint smudges around letters. For those, start around 90% and zoom in on text before downloading.

If a form sets a maximum file size, use a target size instead. The tool lowers quality first and only reduces the image dimensions if the target cannot be reached otherwise. Results are approximate, so check the final size shown before you upload.

When not to convert

• Logos and icons with transparent backgrounds or a few flat colours. They often stay sharper and can be small as a palette PNG.
• Text-heavy screenshots and diagrams where crisp edges matter more than file size.
• Images you will edit again. Each JPG save discards more detail, so edit the PNG and convert once at the end.

Whatever you choose, keep your original PNG. The converted JPG cannot give back the detail or transparency it removed.

Privacy and file details

JPG output is always encoded in your browser, so your PNG is not uploaded during conversion. Re-encoding also removes embedded metadata. The download keeps your original name with -compressed.jpg added. Already have a JPG that is too large? Use the JPG compressor.
