Compress JPG: smaller files, same look

Use WebP or AVIF: both are much smaller. A JPG converted to WebP usually comes out more than 75% smaller and one converted to AVIF more than 70%, measured on real images converted with TinyPNG. WebP opens in more places, so start there. Keep JPG for email, upload forms and anything you share outside the web.

Yes. Every file comes back in its own format.

Yes. They are the same format; only the file extension differs. Old Windows only allowed three letters for the file extension, so JPEG became .jpg. Renaming one to the other changes nothing about the file, so converting to JPEG is the same as converting to JPG, and a .jpeg file converts and compresses like a .jpg.

Compress it here. JPG files usually come out more than 60% smaller, measured on real images compressed with TinyPNG. Each photo gets a quality that still looks right, and we remove all metadata, such as camera details, GPS location and editing history. The developer API can keep it.

No. There's no quality slider, and you can't aim for a size such as 100 kB. We compress every image as far as it goes while it still looks the same, whatever its format. Beyond that, only fewer pixels make a smaller file: an image scaled down in an editor comes out smaller still.

JPG for photos: much smaller, and it opens everywhere. PNG for logos, screenshots and cut-outs: it keeps every pixel and supports transparency. A photo saved as PNG is several times bigger than it needs to be, while flat graphics or art may be much smaller and higher quality with PNG.

Joint Photographic Experts Group (JPEG), the committee that created the format. JPG is the same name cut to three letters.

No. When you convert to JPG, we turn transparent areas white, and we ask before doing it. To keep them, convert to PNG, WebP, AVIF or JPEG XL instead.

Yes. A .jfif file is a JPEG with a different extension. Rename it to .jpg, or drop it here to get a compressed JPG.

Yes, always, even at the highest quality setting. Saving a JPG again can lose a little more detail, so keep your original.

A JPG file is a photo saved in the JPEG format, named after the Joint Photographic Experts Group. JPG files are always lossy: they keep photos small by dropping detail the eye barely notices. They have no transparency. Cameras, phones, websites and email all use it, and every browser, app and email client opens it.

Yes. Web Free compresses 20 images per session, up to 5 MB each, without an account. Once you log in, Web Pro and Web Ultra compress as many images as you like: up to 75 MB each on Web Pro, and up to 150 MB each on Web Ultra. On every plan, an image can have up to 256 megapixels.

Yes. We store your images encrypted, download links expire after 8 hours, and we delete them automatically after 24 hours.

Yes. To keep files small we remove all metadata: EXIF data such as camera details and GPS location, and XMP data such as copyright and editing history. Colour profiles are converted to sRGB, the standard for screens and the web. The developer API can keep the copyright, creation date and location.
