Does converting to PNG preserve transparency?

Yes. When the source has an alpha channel—WebP, GIF, ICO, or another PNG—the transparent areas are carried over unchanged into the PNG.

Will converting a JPG to PNG improve its quality?

No. PNG is lossless, so it stores the decoded JPG pixels exactly, including any compression artifacts already in the JPG. The PNG is usually much larger, so convert only when you need lossless editing or plan to add transparency later.

When is PNG a better choice than JPG or WebP?

PNG fits screenshots, UI graphics, diagrams, and images with text, where lossless compression keeps edges crisp. For photographs, JPG or WebP produce far smaller files.

Which formats can I convert to PNG?

JPG, BMP, WebP, GIF, and ICO images. Drop one or many files and convert them in a single batch.

How to Convert Images to PNG

1
Add your source images
Drop or select JPG, BMP, WebP, GIF, or ICO files up to 5000x5000px each; several files can be queued and converted together.
2
Pick an output size (optional)
Enter a width, a height, or both—leaving one field empty keeps the aspect ratio. Upscaling adds pixels but no new detail, so PNG output looks sharpest at the source size or smaller.
3
Convert to lossless PNG
Click Convert All. The canvas is cleared to transparent before each image is drawn, so see-through areas stay see-through in the PNG.
4
Download the PNG files
Save a single .png with Download, or use Download All to collect every converted file in one ZIP archive.
