Image Convert / Resize

What it's for

Convert an image to JPEG, PNG, WebP or GIF, resize it and set the quality. It also removes hidden metadata, such as camera details and GPS location.

• When a website or form rejects a photo for being too big or the wrong format.
• When you want to share a photo without revealing where it was taken.

How to use it

Choose an image, drop one on the page or paste one (a screenshot, say), or paste an image’s web address and press Load, then pick a format in Save as. For JPEG and WebP, set the quality: lower means a smaller file. Enter a Width or Height and the other adjusts to keep the proportions, or set both to force an exact size. Rotate turns the picture a quarter or half turn, the Flip boxes mirror it, and Crop keeps only the part you give in the original’s pixels (from the left, from the top, width and height; leave any blank for the edge). Width and height then apply to the cropped, turned picture. The preview shows the result, with the old and new dimensions and file sizes, and Download saves it. The format and quality are remembered.

Example

Choose a photo from your phone, which is often several megabytes. Set Save as to JPEG, quality to 0.85 and Width to

1600

The tool shows the new size as a percentage of the original, usually a small fraction. The copy still looks sharp on screen and has no location data.

Good to know

Making an image larger than the original can’t add detail. PNG and GIF ignore the quality setting, and JPEG has no transparency, so transparent areas become white. HEIC photos, the iPhone’s default format, open only in Safari. A GIF has at most 256 colours, so photos look grainier, and only the first frame of an animated GIF is read: to resize or edit an animation, use the Animated GIF Maker.

Loading from a web address only works when the site allows other pages to read its images. Many, such as Wikimedia Commons, do; most others don’t, and then you need to save the image and choose the file. Everything else happens in your browser, and your own files are never uploaded.
