PNG to JPG converter

When PNG to JPG makes sense

PNG is ideal for screenshots, logos and graphics, but it is a poor fit for photographs: a phone photo saved as PNG can be five to ten times larger than a good JPG. If a PNG holds a photo, or you need to meet an upload size limit, converting to JPG is the quickest way to shrink it.

The one thing to decide is what happens to transparency. JPG has no alpha channel, so transparent pixels must be filled with a colour. Myriadfile lets you pick it.

How to convert PNG to JPG

1. Add PNG files. Drop, choose or paste them.
2. Pick a fill colour. White suits documents and most websites. Choose black or a brand colour if the image will sit on a dark background.
3. Set quality. 90% for photos. For screenshots with small text, 92–95% keeps text crisp.
4. Download. Each file shows its size reduction. Download individually or as a ZIP.

Settings explained

Fill for transparent areas

Every fully or partly transparent pixel is blended onto this colour.

Quality

JPG compression level. Lower values make smaller files with more visible artefacts around sharp edges.

Max size per image (KB)

Useful for forms and email attachments with size limits.

Screenshots: JPG or keep PNG?

Screenshots of text and interfaces often compress better as PNG than as JPG, and JPG adds faint ringing around letters. Convert a screenshot, look at the savings badge, and keep whichever is smaller and sharper.

Need it under a specific size?

Use the Max size field, or the resize to 100 KB tool if the image is for an application form with pixel and KB rules.

Troubleshooting

The JPG is larger than the PNG

The PNG is probably a simple graphic with few colours. Keep it as PNG.

There is a halo around the edges

Soft edges were blended with the fill colour. Choose the colour of the final background.
