PNG to JPG

About the PNG to JPG

PNG is perfect for graphics and transparency, but it is a poor choice for photographs — a photo saved as PNG can be several times larger than the same image as JPG. Converting photos and screenshots to JPG makes them far smaller and easier to email or upload.

This PNG to JPG converter changes your PNG images to JPG in your browser, letting you set the quality and pick a background colour to replace any transparent areas. Convert one or many, and download instantly.

How to use the PNG to JPG

1. Drop in your PNG images (one or several).
2. Choose the JPG quality and a background colour for transparent areas.
3. Click Convert.
4. Download each JPG, or all of them as a ZIP.

Key features of the PNG to JPG

• Converts PNG to JPG and shrinks photo file sizes
• Batch convert multiple PNGs at once
• Background colour fills transparent areas
• Quality control with individual or ZIP download
• Runs locally — nothing is uploaded

How the PNG to JPG works

This tool processes your pictures using the browser's built-in Canvas API and standard image codecs for JPG, PNG and WebP. Resizing, cropping, conversion and compression all happen on your own device, so the image data is never sent to a server. Compression balances file size against visual quality using established lossy and lossless techniques appropriate to each format.

Tips & best practices

• PNG is best kept for logos and graphics with transparency; JPG is the right choice for photographs.
• Because JPG has no transparency, pick a background colour (usually white) that suits where the image will appear.
• For a photo-heavy PNG, converting to JPG can cut the file size by 70% or more with no visible difference.

Standards & accuracy

Uses the browser's native Canvas API and standard web image formats (JPG, PNG, WebP) — images are never uploaded.

For the best results, resize an image to the dimensions you actually display before compressing, and choose WebP for the web where a smaller file at the same quality is the priority.

Privacy & security

The PNG to JPG runs entirely inside your web browser. Your data — whether that is a file, figures or text — is processed on your own device and is never uploaded to a server, stored or shared. There is no signup and no account, so you can use it as often as you like while keeping full control of your information. This makes it a safe choice even for confidential and sensitive work.
