Converting PNG → JPG
Why convert PNG to JPG?
PNG files of photos and large screenshots can be several megabytes. JPG stores the same image far more compactly, which matters for email, upload limits and page speed.
Much smaller photos
A photographic PNG commonly shrinks by 70–90% as a JPG. That helps with upload forms, email attachments and image-heavy web pages.
Universal compatibility
JPG opens in every email client, CMS, printer and government portal — useful when a site rejects PNG uploads.
Transparency becomes white
JPG has no alpha channel, so transparent areas are flattened onto a white background. Keep PNG or use WebP for logos that need transparency.
Need an exact size?
After converting, run the JPG through the Image Compressor to hit a precise target like 100KB or 200KB.
