When Do You Need to Change PNG to JPG?
Converting PNG to JPG is one of the most common image tasks. Website owners change PNG to JPG to reduce page load times — JPG files are typically 60-80% smaller than PNG files. Email users convert PNG screenshots to JPEG to stay under attachment size limits.
Social media platforms sometimes handle JPG uploads better than PNG. Online forms and job application portals often require JPEG format specifically. Photographers and designers save PNG as JPEG when they need to share work without the larger file size.
With OneWeeb, you can convert PNG to JPG without uploading your images to any server. Your screenshots, personal photos, work documents, and design files stay on your device throughout the entire process.

Frequently Asked Questions
How do I save a PNG as a JPEG?▼
Upload your PNG file to OneWeeb's converter, set your preferred quality, and click Convert. The tool converts PNG to JPG entirely in your browser — no upload to any server. Download your JPEG file instantly.
How do I change PNG to JPG without losing quality?▼
Set the JPG quality slider to 90-100 for minimal quality loss. JPG is a lossy format, so there will always be a tiny difference, but at high quality settings it is virtually unnoticeable to the human eye.
Does this tool upload my PNG files?▼
No. OneWeeb converts PNG to JPG entirely in your browser using the Canvas API. Your files never leave your device. You can verify by turning off your internet — the conversion still works.
Why convert PNG to JPG?▼
JPG files are typically 60-80% smaller than PNG files. This is useful for websites (faster loading), email attachments (smaller size), social media uploads, and saving storage space. PNG is better when you need transparency or lossless quality.
What is the difference between JPG and JPEG?▼
There is no difference. JPG and JPEG are the same format. The shorter .jpg extension exists because older Windows versions only supported 3-letter file extensions. Both produce identical image files.
Can I convert multiple PNG files at once?▼
Yes. Select multiple PNG files and convert them all to JPG in one batch. Each converted file can be downloaded individually.
What happens to transparency when converting PNG to JPG?▼
JPG does not support transparency. When you convert a PNG with a transparent background, the transparent areas become the background color you choose (white by default). You can also select black or custom colors.
