Quick answer

Drop PNG or JPG — or paste from clipboard
Or click to browse — multiple files OK
Soft limit: about 40 files per round (very large batches can slow the tab). Drop again for the rest — processing is not uploaded to our servers.
PNG vs JPG — which should you use?
PNG is lossless and keeps transparency, so it is ideal for logos, screenshots, and graphics with sharp edges. JPG is lossy and much smaller, which suits photographs and upload forms with tight size caps. Converting PNG → JPG shrinks the file; converting JPG → PNG gives you a lossless copy (though not the original quality back).
Why did my transparent PNG go white?
JPG cannot store transparency. When you convert a transparent PNG to JPG, the see-through areas are filled — this tool fills them white so they never turn black. Keep PNG if transparency matters.

Frequently asked questions
How do I convert PNG to JPG?
Drop your PNG files above with the direction set to PNG → JPG and download the JPGs. It runs in your browser using the Canvas API — not uploaded to our servers for processing.
Why is my transparent PNG turning white as a JPG?
JPG does not support transparency, so transparent areas are flattened onto a white background. If you need to keep transparency, stay in PNG (or convert JPG → PNG here).
Can I convert JPG to PNG too?
Yes — switch the direction dropdown to JPG → PNG. Useful when a form or editor needs PNG.
How do I convert an image to JPG with a white background?
Set direction to PNG → JPG and convert — this tool automatically fills any transparent area with white before flattening to JPG, since JPG has no transparency channel. That is the default behavior; no separate setting needed.
Will the JPG lose quality?
JPG uses lossy compression, so there is a small quality trade-off for a much smaller file. This tool encodes at high quality (about 92%), which looks visually identical for photos.
Can I convert many files at once?
Yes — drop multiple files and download a ZIP. Very large batches process about 40 at a time; drop again for more. Everything stays in your browser — files are not uploaded to our servers for processing.
Do you upload my images?
No. Decoding and re-encoding happen in your browser. Turn on airplane mode after the page loads and it still works.
