Guides Sizes, how-tos and alternatives.

Short, practical answers, each with the tool that does the job, all in your browser.

Instagram image sizes: Instagram shows the same photo at different shapes depending on where it appears. Here are the sizes that matter, and how to make every version from one photo in a few seconds.
LinkedIn image sizes: LinkedIn crops images differently on phones and computers. These sizes look right on both.
YouTube thumbnail size: YouTube asks for thumbnails at 1280 × 720 pixels, in a 16:9 shape, and no larger than 2 MB. Here's how to hit both.
X image sizes: X crops images in the timeline, so the right shape decides what people actually see.
App Store screenshot sizes: Apple only asks for one iPhone size and one iPad size; it scales them for every other device. Google Play is more flexible. Here's what each needs.
Remove a background: Most background removers send your photo to a server. Cutout runs the model in your browser instead, so the photo never leaves your device.
Compress images: Online compressors usually upload your images to shrink them. Compress does it on your device, in batches, and can aim for an exact file size.
Password-protect a link: Sharing a private folder, a draft or a booking page? Link Lock turns any address into a locked link that asks for a password first.
Blur faces in a photo: Before you share a crowd shot, an event photo or a screenshot with people in it, blur the faces in seconds.
Remove photo metadata: Photos from phones often carry the exact place they were taken. Metadata Cleaner shows what's hidden in each file and removes it.
A remove.bg alternative: remove.bg is quick and good at what it does, and it works by uploading your photo to its servers. If you'd rather keep photos on your device, or want full-resolution cutouts without credits, Cutout is an alternative.
A TinyPNG alternative: TinyPNG is a well-known way to shrink images, and it does it by uploading them. Compress does the same job in your browser, and can also aim for an exact file size.
A Squoosh alternative: Squoosh is excellent and, like One Design, runs in your browser. It works on one image at a time. If you have a folder of images, Compress handles them as a batch with the same privacy.
