Before placing a picture on a website, it must: a) cut to size b) optimize the web by performing a .jpg image compression. Adding images without optimizing them will sometimes take up several times more space, will slow down on mobile devices and may affect your website’s ranking in search engines (google, yandex, etc.). Image optimization can be done in Adobe Photoshop with the Save for Web feature or using one of the following online optimizers:

1) www.jpeg-optimizer.com it optimizes and can indicate width, height will be proportional.
2) www.tools.dynamicdrive.com it only optimizes but does not cut.
3) www.cutmypic.com this allows you to crop the desired part of the picture.
4) www.image.online-converter.com this optimizes and can indicate both height and width, but if the picture is not square, it will compress.

!We strongly advise you to devote time and attention to this.

The same applies to .pdf files. We optimize the size using www.pdfresizer.com or other online tools.
