PNG to JPG Converter
Convert PNG — or any other image format — to JPG in bulk, with a live before/after file size comparison, entirely inside your browser.
Why convert PNG to JPG?
PNG uses lossless compression, which keeps every pixel exact but often produces much larger files than JPG for photos. JPG's lossy compression trades a small, usually invisible amount of detail for a significantly smaller file, making it the better choice when file size matters more than pixel-perfect accuracy.
Since JPG doesn't support transparency, any transparent areas in the PNG are filled with white when converted.

Features & benefits
Why this runs entirely in your browser
The conversion uses the browser's own Canvas API to redraw and re-encode the image locally, so the original file never leaves the device — no upload, no server-side processing.
Common uses
Shrinking a large PNG screenshot before sharing it, converting a design export for a web page where transparency isn't needed, or preparing photos for email attachments with strict size limits.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
JPG doesn't support transparency, so any transparent pixels are filled with white in the converted file.
JPG uses lossy compression, so at lower quality settings some fine detail is traded for a smaller file. At high quality settings, the difference is usually imperceptible.
85-95% quality is a good default that keeps files noticeably smaller than PNG while looking visually identical for most photos.
No hard limit is enforced, but very large images may take longer to process since everything runs in the browser tab.
No. All conversion happens locally in your browser. Nothing uploaded here is sent to a server, stored, or shared.
