Which format compresses best?

WebP usually produces the smallest files at the same quality — typically 25 to 35 percent smaller than PNG or JPEG. Use PNG when you need lossless transparency.

Can I convert PNG to WebP?

Yes. Choose WebP as the output format to convert PNG or JPEG files to WebP, with an adjustable quality slider.

Yes — compression happens in your browser, so your files are never uploaded.

Compress Images Without Wrecking Quality

Heavy images are the number-one cause of slow websites. Compressing and converting them to a modern format like WebP can cut file sizes by a third or more — improving load speed, Core Web Vitals, and SEO — with no visible quality loss. This tool does it instantly and in bulk, right in your browser.

Which format should I choose?

WebP — best overall for the web; smallest files at a given quality, supports transparency.

JPEG — great for photos without transparency; widely compatible.

PNG — lossless; use for logos and graphics that need crisp transparency.

Tips

For web images, a quality of 75–85% is usually indistinguishable from the original.

Set a max width (e.g. 1920px) so oversized photos are downscaled before compressing.

Compare the before/after sizes shown on each card to find your sweet spot.

Will PNG get smaller?

PNG is lossless, so re-encoding a PNG only helps a little. To really shrink a PNG, convert it to WebP — often a huge saving with no visible difference.
