The image rotation angle is set in degrees (for example: 90). If the rotation angle is a value other than 90, 180, or 270, empty areas can be filled with a selected color or remain transparent (if the output format supports transparency).


How to Use Online Image Converter

  • Before the file conversion, you must consent to data processing on our servers – this is a standard procedure. We do not use your files or data in any way and do not pass it on to third parties.
  • Afterward, you may select automatic start or start the conversion by manually pressing the Convert button.
    • If you check the box next to Start conversion after upload, take these steps in advance (before adding the files): select the desired output format, and configure the necessary settings and operations.
    • If you want to convert your files by pressing the Convert button, the order of your actions is not important.
  • After adding images, the service uploads your files to our server and converts them to the format of your choice while applying the specified settings and operations. You can read how it works below.
  • When the conversion is complete, you can save each converted file to your computer using the download link or get resultant files as a ZIP archive.

Online Image Converter’s image editing operations

Currently, four operations are available, which are performed in the following sequence:

  • Resize – allows you to change the size of your photos. This operation is quite flexible since you can apply the same width or height to all your images. You can also specify both sizes, in which case the Converter will fit your image into the specified dimensions.
    • Check the Keep proportions setting – in most cases, it should be enabled when resizing. When it’s on, the image will keep the original aspect ratio of the source image. Usually, the size you specify will apply on the long side, and on the short side, the size will be smaller.
    • The DPI parameter (dots per inch) does not change the pixel size of the images but is used to specify image resolution, linking the inches and pixels together. Not all images have the ability to write DPI value inside the file, and in this case, this parameter is ignored.
  • Crop – changes the image dimensions by cropping them. Four crop types are available:
    • Margins – for proper cropping, specify the width of each margin separately. This mode is suitable if you know the exact margin value. In this case, cropping does not depend on the size of the image itself. 
    • Rectangle (2 coordinates: left-right, top-bottom) – the upper left and lower right coordinates are specified in pixels, counting from the upper left corner. In this case, the size after the operation will be the same for all images.
    • Rectangle (1 coordinate, left, top, width-height) – similar to the previous setting, except that the upper left corner, width and height from the specified coordinate are used. As with the previous setting, the size after the operation will be the same for all images. 
    • Auto crop by margins – performs cropping of images according to a specified color. For example, if you need to remove the white margins after scanning, select this color in the dialog box and try different Tolerance values until you are satisfied with the result. In this mode, you can get completely different image sizes because the algorithm is applied to each image individually.
  • Rotate – rotates your images to a certain angle. There’s an ability to rotate to any arbitrary angle, not just an angle divisible by 90 degrees. When you set a rotation angle that is not a multiple of 90 degrees, an empty space appears in the image. To fill this space, you can select any color via the Background setting.
  • Effects – applies a selected effect onto your images.
    • Blur – softens a photo, making it suitable for retouching. This effect smoothes transitions by averaging pixels near the hard edges of certain lines and shaded areas in the picture. We recommend applying the Blur effect to photos to reduce the effect of noise or to smooth out grainy photos created at high light sensitivities.
    • Sharpen – sharpens images and improves their contrast. It is the opposite of the Blur effect, but you can’t return the original sharpness to an image blurred with the Blur effect because the algorithms of these effects are different. In any case, the Sharpen effect does what it is intended to do – image sharpening.
    • Emboss – is a decorative effect designed to “uplift” certain parts of the image relative to its background. This filter finds the contrasting lines of the image and adds shadows to them to simulate embossing. Some areas of the image become convex, and others concave.
    • Watercolor – serves for decorative purposes only. Use it to make your photos look like watercolor paintings. This effect blurs and smooths out large areas with solid color, preserving most contrasting transitions. It goes without saying that the watercolor effect cannot compare to an artist’s work. Nevertheless, it can be successfully applied if the photo contains few small elements.
    • Smoothing noise – is mainly used for smoothing images with a limited color range, such as GIFs or 1-bit images. However, this effect can also be applied to full-color images. This effect adds noise to the contrasting edges of the image (the contrast of the added pixels is similar to that of the original).
    • Maximum – this effect increases the brightness and size of the light areas of the entire image.
    • Minimum – reduces the brightness and increases the size of the dark areas of the entire image.
    • Negative – the negative effect is used to invert the colors of an image and create a negative image from your actual image. Apply this effect to transform the colors of a picture into non-traditional colors. For example, shades of blue will become shades of red, and light shades will become dark shades.
    • Grayscale – converts the image so that it contains information about the black level only. 0 is “white”, 255 is black. All other values correspond to different shades of gray. Besides creating black-and-white images, the grayscale channel is used to apply various effects, transparency masks, alpha channels, and selection. In addition, any color channel can be represented as black and white.
    • Sepia – a decorative effect. Use it to make your photos look oldish. This effect actually converts the spectrum of the image to a brownish color, which simulates faded photos and yellowed photo paper.


Is it safe to convert images with your service?

Yes, it is absolutely safe. The connection between you and the server is encrypted, and only a limited number of people from our company have access to the server. Besides, all your files are deleted within 24 hours after conversion. You can also instantly delete your files from our storage by clicking the Delete from server button under the download link.

If using online services for file conversion is not an option for you, please get in touch with us, and we will recommend the proper software for this task that works offline.

What is “batch processing”?

The word “batch” means mass conversion, i.e., you add not one file but several ones at a time. For example, upload 50 images that you need to convert with the same parameters, and the server will convert them all. It is done in a few clicks without installing any third-party applications.

Do I need to change the format settings?

By default, all settings are set to optimum values, but sometimes you may need to get images with specific parameters. For example, if you want to get a BMP with 1-bit color depth or a TIFF with CCITT Fax4 compression, you can easily accomplish that.

What is the number of images that I can convert with your service?

Our image converter is completely free of charge, and the number of files is unlimited. We do not restrict our users regarding the number of files for batch processing.

How do I reset the format and operations settings?

Currently, the website doesn’t remember your choices, so just reload the page and start working from scratch.

What input formats are supported?

Online Image Converter supports most existing image formats, from very rare formats such as DDS to modern ones such as WEBP or Apple’s HEIC.

Do you support multi-page files?

Yes, if you upload a multi-page file and convert it to a format that also supports multiple pages, it will be saved as a multi-page file. If the output format does not support multiple pages, all pages will be archived in one file. For example, when converting from multi-page TIFF to JPG, you will get several images in JPG format, numbered page by page.

Do you add any watermarks or other marks to the images as an advertisement for your service?

No, we don’t add any marks. If you want to help us make the Internet a better place, just spread the word and share this page with your friends.
