About these guides
The guides are written by the Img Hut team, the people who build the tools on this site. They focus on decisions you actually have to make, such as which format to save in, which quality setting to try first and how large an image really needs to be, and they explain the reasoning so that you can adapt it to your own situation.
Where a guide quotes figures that other companies control, such as the image sizes social networks recommend, it says so and dates them, because platforms change their layouts regularly. Each guide links to the tools that help you put the advice into practice, all of which run in your browser without uploading your pictures.

Tools used in the guides
Compress Image
Reduce JPG, PNG or WebP file size by re-encoding at the quality you choose, with a before-and-after comparison.
Resize Image
Change width and height in pixels or by percentage, with an aspect-ratio lock and smooth downscaling.
Crop Image
Draw a selection freely or lock it to 1:1, 4:5, 16:9 and other ratios, and see its exact size in pixels.
PNG to JPG
Convert PNG to JPG with adjustable quality and your choice of background color for transparent areas.
JPG to PNG
Save a JPG as a lossless PNG so that further edits do not add new compression damage.
Image to Base64
Encode an image as raw Base64, a data URI, a CSS background or an HTML img tag.
Favicon Generator
Create favicon.ico, 16/32/48 px PNG favicons, an Apple touch icon and 192/512 px app icons.
