Подбор и оптимизация изображений для сайта

Resizing images

Use the API to create resized versions of your uploaded images. By letting
the API handle resizing you avoid having to write such code yourself and
you will only have to upload your image once. The resized images will be
optimally compressed with a nice and crisp appearance.

You can also take advantage of intelligent cropping to create thumbnails
that focus on the most visually important areas of your image.

Resizing counts as one additional compression. For example, if you upload
a single image and retrieve the optimized version plus 2 resized versions
this will count as 3 compressions in total.

To resize an image, call the method on an image source:

The describes the way your image will be resized. The following
methods are available:

Scales the image down proportionally. You must provide either a target
or a target , but not both. The scaled image will have
exactly the provided width or height.

Scales the image down proportionally so that it fits within the given
dimensions. You must provide both a and a . The scaled
image will not exceed either of these dimensions.

Scales the image proportionally and crops it if necessary so that
the result has exactly the given dimensions. You must provide both a
and a . Which parts of the image are cropped away is
determined automatically. An intelligent algorithm determines the
most important areas of your image.

A more advanced implementation of cover that also detects cut out
images with plain backgrounds. The image is scaled down to the
and you provide. If an image is detected with a
free standing object it will add more background space where
necessary or crop the unimportant parts. This feature is new and
we’d love to hear your feedback!

If the target dimensions are larger than the original dimensions, the image
will not be scaled up. Scaling up is prevented in order to protect the
quality of your images.

Saving to Google Cloud Storage

Before you can store an image in GCS you will need to generate an access
token with a service account.

We still need to create a piece of example code for this language
that generates an access code. In case you have a working example
ready, please share your code!

Once you have generated the access token you can then save the optimised
image directly to GCS by calling the method on an image source:

You need to provide the following options in order to save an image on
Google Cloud Storage:

Specify to store to Google Cloud Storage.

The access token for authenticating to Google’s Cloud Platform. Find out
how to generate these tokens with the example above.

The path at which you want to store the image including the bucket
name. The path must be supplied in the following format:
.

The following settings are optional:

(experimental)

You can add a header to control browser caching of the
stored image, with for example: . The full list

Description

Make your website faster by optimizing your JPEG and PNG images. This plugin automatically optimizes all your images by integrating with the popular image compression services TinyJPG and TinyPNG.

Features

• Automatically optimize new images on upload.
• Advanced background optimization to speed up your workflow.
• Optimize individual images already in your media library.
• Easy bulk optimization of your existing media library.
• Automatically resize huge image uploads by setting a maximum width and/or height for more reasonable browser display.

• See your usage on the settings page and during bulk optimization.
• Color profiles are automatically translated to standard RGB color.
• Convert CMYK to RGB to save more space and add compatibility.
• Dashboard widget with your total savings.
• Optimize and resize uploads with the WordPress mobile app.
• No file size limits.

How does it work?

After you upload an image to your WordPress site, each resized image is uploaded to the TinyJPG or TinyPNG service. Your image is analyzed to apply the best possible optimization. Based on the content of your image an optimal strategy is chosen. The result is sent back to your WordPress site and will replace the original image with one smaller in size. On average JPEG images are compressed by 40-60% and PNG images by 50-80% without visible loss in quality. Your website will load faster for your visitors, and you’ll save storage space and bandwidth!

Getting started

Install this plugin and follow the instructions to set up your account. With a regular WordPress installation you can optimize roughly 100 images each month for free. The exact total depends on the number of thumbnail sizes that are in use in your WordPress installation. You can change which of the generated thumbnail sizes should be optimized on the Settings > Compress JPEG & PNG images page. Once installed you can also switch to a paid account which removes the limits and allows you to optimize as many images as you like.

Optimizing all your images

You can bulk optimize your existing JPEG and PNG images all at once by going to Media > Bulk Optimization. Clicking on the big button will start optimizing all unoptimized images in your media library.

Multisite support

The plugin is fully multisite compatible and you can set the API key for all sites by defining the key in your wp-config.php file. View the installation instructions for more information.

WooCommerce compatibility

This plugin is fully compatible with WooCommerce. However, we have discovered that WooCommerce may be trying to regenerate image attachment metadata over and over again on each page visit. If you are using WooCommerce please follow the tips from the support section. This may make your WooCommerce shop even faster than it was before.

Compressing images

You can upload any JPEG or PNG image to the Tinify API to compress it. We
will automatically detect the type of image and optimise with the TinyPNG or
TinyJPG engine accordingly. Compression will start as soon as you upload a
file or provide the URL to the image.

Example upload from file

You can upload a local file. The post data contains the image binary.

For example, if you have a file named in the current
directory:

Example upload from URL

You can also provide a URL to your image instead of having to upload it.
The API accepts a JSON body with the image URL as a location.

For example, if you have as your source:

Example download request

The compressed image can be retrieved by using the URL in the
header from the previous step.

For example, you can save the compressed image to a file named
and open it:

Saving to Amazon S3

To save an image to S3, call the method on an image source:

You need to provide the following options in order to save an image on
Amazon S3:

Specify to store to Amazon S3.

stored image, with for example: . The full list
of directives can be found in the MDN
web docs.

The user that corresponds to your AWS access key ID must have the
and permissions on the paths of the objects you
intend to create.

Error handling

The Tinify API uses HTTP status codes to indicate success or failure. Any
HTTP errors are converted into exceptions, which are thrown by the client
library.

There are four distinct types of errors. The exception message will contain
a more detailed description of the error condition.

There was a problem with your API key or with your API account. Your
request could not be authorized. If your compression limit is reached,
you can wait until the next calendar month or upgrade your subscription. After verifying your
API key and your account status, you can retry the request.

The request could not be completed because of a problem with the
submitted data. The exception message will contain more information.
You should not retry the request.

The request could not be completed because of a temporary problem with
the Tinify API. It is safe to retry the request after a few minutes.
If you see this error repeatedly for a longer period of time, please
contact us.

The request could not be sent because there was an issue connecting to
the Tinify API. You should verify your network connection. It is safe to
retry the request.

You can handle each type of error separately:

If you are writing code that uses an API key configured by your users, you
may want to validate the API key before attempting to compress images.
The validation makes a dummy request to check the network connection and
verify the API key. An error is thrown if the dummy request fails.
