Editing an image is, nowadays, an almost daily thing. Adding filters on Instagram, retouching a selfie before uploading it, creating cover images for Twitter or Facebook… Apps like Snapchat and Instagram, but also image sharing services like Tumblr, Imgur and Flickr live from strong visuals.

However, not everyone can afford to have Photoshop installed on their computer. Let alone the limited space on your phone that is too precious to be used for the one millionth app. Luckily, you can edit and manipulate photos online!

Image Converter FAQs

 

Why Do I Need An Image File Converter?

There are several reasons for why you may have to convert images from one format to the other. Depending on your needs, the needs of your friends or customers, or depending on the programs you use for viewing or editing images, certain image file formats will not cut it.

Here are some of the most popular reasons why to use an online image converter to convert your images into another format.

  • You can not open/view an image someone sent you.
  • You want to turn a video into an animated gif.
  • You want to show your customers a preview of your design/work.
  • You can not open a camera RAW image.
  • You want to scale a shape or outlines without quality loss.
  • You want a quick screenshot of a webpage.
  • You can not upload an image to Facebook, Twitter, Flickr or another social media or image sharing platform.
  • You want to change a Windows desktop icon to your own image.

 

How Do I Convert Image Files?

On Online-Converter.com you can find the most common image converters. All you have to do is choose the converter you want to use and provide the file you want to convert. Leave all the rest to us.

OC_ImageConversion

Under 1. you can choose if you want to convert a file from your computer or hard drive, paste the link or choose a file from a cloud storage.

The optional settings under 2. are mandatory. Read on if you want to know what they will do to your image, but you don’t need them for a successful conversion.

And, last but not least, click on “Convert file” under 3.

 

Now, all you have to do is wait until the conversion is done. The output will be downloaded to your computer and device (depending on your browser this works automatically).

 

What Converter Should I Choose?

Depending on your needs, you can choose different converters. Or more precisely: you can choose different output image formats.

Raster Images:

  • BMP (most commonly associated with MS Paint)
  • GIF (can contain transparency and animation, but with low quality or high file size)
  • JPG (most common image file with good quality and file size ratio)
  • PNG (can contain transparency, often better quality for uploads on social media)
  • TGA (commonly used for animations and video editing)
  • TIFF (stores images in very high quality; can also store vector image information)
  • WEBP (open standard image by google; more about WebP images)

Vector Images:

  • EPS (common and widely distributed format by Adobe)
  • SVG (common vector image format)

Other:

  • ICO (Windows Desktop Icons)

 

 

For sharing, sending and uploading to social media and the web, we suggest using the JPG converter or the PNG converter if the image contains transparency. Animated GIFs can be converted and created using the GIF converter.

To convert vector images into a widely supported format, convert them to SVG. And to create your own Windows desktop icons out of any graphic, use the ICO converter.

 

What Are Raster And Vector Images?

Now you know about some of the most common image file formats. But what exactly does vector and raster image mean and what distinguishes those two formats?

Most images you will come across are raster images. In these files, the image or photo information is saved for each pixel in the image. Contrary to that, vector images store image data using mathematical formulas. What does that mean?

In short: Raster images can only be scaled down aka made smaller. When you want to increase the size of a raster image, you have to expect a, more or less, loss in quality. Vector images can be scaled up without a problem and thus made bigger and smaller without losing the quality of the image.

More on vector images.

 

What Are Optional Settings?

The optional settings of image.online-convert.com are not mandatory for the conversion. You can leave them completely empty and will still get exactly the conversion you wanted.

However, using these options enables you to add some minor image editing and enhancement to your converted image.

If you want to know more about the single options available, check out our article that explains the optional image settings.

 

What Else Can I Do With An Image Converter?

An online image converter can do more than simply convert your images from one format to the other. Conversion between different file types is also possible:

  • Convert a video to GIF to create an animated gif
  • Convert a vector graphic to raster image to show off designs, layouts, etc.
  • Convert documents to image for easier sharing and uploading to image sharing websites
  • Convert a website to image to get a screenshot of the whole page

If you are familiar with Online-Convert.com’s free image converter, you have also already noticed the optional settings provided when converting your image. Next to converting your picture or photo into another format, you can use these options for some basic image editing.

But what are these options good for?

This is the question we will answer for you today! There is a set of optional settings you can use when converting your image to JPG, TIFF, WEBP or even animated GIF. The options are all the same, except for ICO which we will have a look at at the end of the article as well.

 

Optional Settings For Image Conversion

OC_ImageOptions

These are the optional settings you can choose from when using one of the Online-Convert.com image converters. Lets go through them one after the other. Of course, we will also provide you with visuals to see the difference between single options!

 

Change Size

Rather self-explanatory, this option changes the size of the target file. The format is the following: width x height

OC_ImageOptions_ChangeSize

Entering one value, either for width or height, will proportionally change the other value as well. This way, the dimension of the image will stay the same.

Setting both values will cause the image to be scaled to fit them both. The resulting image will be distorted according to the values set:

Image Settings
Image scaled to 1024×500 px

Color

Color, just like the name suggests, changes the colors of the uploaded image. There are six predefined options to choose from: Colored, Gray, Monochrome, Negate, Year 1980 and Year 1900. Only one of the options can be chosen.

In this case, a picture tell you more than words can, thus here’s an overview of what the different color options do to your picture:

Image Settings_Color

Enhance

The options given under enhance will add to the image quality. There are, again, six options to choose from: Equalize, Normalize, Enhance, Sharpen, Antialias and Despeckle. Here, however, several options can be selected and thus the effects they have can be mixed.

Image Settings_Enhance

DPI

DPI stands for “dots per inch” and in the image it denotes the amount of dots in a line with a size of one inch. There are a few common DPI values used for images, however, you can choose the number freely.

OC_ImageOptions_DPI

For more information on DPI read up here: Wikipedia: Dots Per Inch.

 

Basic Image Editing With A Converter

Making use of all these options provides you with some basic image editing options for your images. Lets have a look how an image with several options set will turn out:

Options For ICO Conversion

Last but not least, let’s have a look at the optional settings available for ICO conversions.

OC_ImageOptions_ICO

The only options available for ICO are “Change Size” and DPI. The reason for this is that ICO files are not typically used as normal image extensions. It’s rather a file format used to display programs, folders, etc. on a computer that runs with Microsoft Windows.
