About these png converters

PNG is the workhorse format for screenshots, logos, UI graphics and anything that needs sharp edges or transparency. The trade-off is size: PNG files are often far heavier than they need to be.

These tools convert PNG into lighter formats, compress and resize the files you keep as PNG, and handle the edits PNG is best at, like transparency effects and rounded corners. Everything runs locally in your browser.

When PNG is the right format

PNG is lossless: every pixel is preserved exactly, which is why screenshots, logos, line art and text stay perfectly crisp. It is also the most widely supported format with full transparency, which makes it the default for graphics that sit on top of other content.

The cost is weight. A photographic PNG can be five to ten times larger than the same photo as JPG or WebP, so PNG is best reserved for graphics, and photos are best converted to a lossy format.

Making PNG files lighter

For graphics staying as PNG, the compressor reduces size while keeping edges sharp and transparency intact. For website use, converting PNG to WebP usually gives the biggest saving: WebP keeps transparency and renders the same in every modern browser.

Resize before publishing too. A full-resolution screenshot displayed in a 700-pixel column carries weight no one ever sees, and resizing first compounds with compression.

PNG Converters FAQ

How do I make a PNG file smaller?

Compress it with the PNG compressor for a lighter file in the same format, or convert it to WebP for the biggest saving on websites. Resizing oversized images first helps even more.

Does converting PNG to WebP keep transparency?

Yes. WebP fully supports transparency, so logos and graphics with transparent backgrounds convert cleanly and render the same in all modern browsers.

What is a Base64 PNG used for?

Base64 turns the image file into text so it can be embedded directly in HTML, CSS, JSON or code without a separate file. The Image to Base64 tool generates it, and Base64 to Image decodes it back.

Should I use PNG or JPG for photos?

JPG. Photos have soft gradients that JPG compresses extremely well, while PNG stores them losslessly at several times the size. Keep PNG for screenshots, logos and transparency.
