Batch PNG to JPG Converter
Convert PNG to JPG online for free. 100% secure, fast, and private local file conversion directly in your browser. No software installation required.
Why convert PNG to JPG?
PNG preserves every pixel, but photos stored as PNG are enormous — often five to ten times the size of the same image as JPG. Phone camera shots, scanned documents with photographic content, and screenshots with photo regions all balloon when saved as PNG. Anyone managing photo libraries, sending large attachments, or running out of cloud storage converts PNG photos to JPG to reclaim space without losing what the eye can see. It is the classic trade: lossless source, practical delivery.
WasmConvert re-encodes PNG to JPG locally in your browser with a quality control that decides how aggressively the file shrinks. For photographs, quality around 85% typically cuts file size by 80-90% with no obvious difference. Because JPG cannot store transparency, the converter lets you pick the background color that replaces PNG's transparent areas before encoding. Everything stays on your device, so private archives slim down offline, and batch conversion trims an entire folder in one pass.
Common use cases
- Shrinking PNG photo scans or camera exports so they fit in emails and messaging apps.
- Reclaiming cloud storage and device space from photo-heavy PNG folders.
- Preparing PNG screenshots with photographic content for blog posts where JPG's smaller size matters.

PNG is a lossless raster image format that supports transparent backgrounds. It is the format of choice for icons, logos, and web graphics where detail and clarity are more important than file size.
JPG (or JPEG) is the most widely used image format globally. It uses lossy compression to significantly reduce file size while maintaining acceptable image quality, making it ideal for photographs.
Pro tips for PNG to JPG conversion
- Use quality 80-90% for photos; below 70% banding and blocking become visible on skies and skin.
- PNG transparency becomes a solid color in JPG — choose a background that matches where the image will be placed, or it will look like a white box.
- Never convert PNG with text, logos, or sharp line art to JPG for final delivery; halos around edges will appear at low quality.
