Best 10 Tools to Batch Convert & Resize Images

Most of the time we require some tools that can convert or resize our images in batch processing. Because if we try to convert all the images one by one then it becomes a ridiculous process. But, a batch convert can save our valuable time. We can easily batch convert or resize images with the help of some tools available.

Nowadays mostly used cameras are digital cameras. And digital cameras have high resolution that increases the size as well. If you are working over a website or writing a blog then you will require a small size file. So, your website will not face any issue in loading.

Having files with high resolution is great when you want to view them with the best quality and for printout. But when it comes to distributing them to others, uploading to online photo albums or just keeping them on your phone can be an issue. Trying to do it with massive files is a waste of time and bandwidth.

Shrinking your photos to a lower resolution or converting them to a more size efficient format before emailing or uploading is a good solution. It is far easier to shrink a 10MB JPEG file down to 1MB and send that instead while only noticing a minute drop in quality.

There are plenty of batch image tools out there, but many of them require installation and most are limited to one particular operating system. In a lot of cases, it is just faster and more convenient to use free online tools instead because they are accessible from anywhere at any time.

Best 10 Tools to Batch Convert & Resize Images

Here we are going to provide a list of the best 10 tools for batch convert. The list may include both kinds of tools that is whether desktop App or Online tools. I used to prefer online tools only. Because they are easily accessible from anywhere. But, desktop App is also a good option for those who do not want to use online applications.

Here are 10 freeware tools to help you in batch convert and resize multiple images.

  1. Bulk Resize Photos
  2. Shrink Pic
  3. TinyPNG
  4. Picture Resizer
  5. CloudConvert
  6. FotoSizer
  7. Resize Pic Online
  8. EasyImage Sizer

  10. FastStone Photo Resizer

Bulk Resize Photos

It is very simple in use. Use drag and drop facility. Select the images that you want to resize. The website said that it can resize 150 images into 1 minute that is quite impressive. You can select the images and can test.

Bulk Resize Photos

You can scale in five ways: percentage, longest side, width, height, or exact size. Everything is client-side so it is really fast and there is no uploading necessary. You can also use the advanced settings to change formats between JPG and PNG.

Bulk Resize adjust image quality, set the background color, and even add padding to prevent stretching.

Shrink Pic Batch Convert

It is a good application for those who want to email so many images or upload batches of files to online image galleries etc. Just install Shrink Pic. Then it automatically detects when you are sending large photo files and compresses them in the background.

There is no need for setup, no operating instructions. Just send your photos normally and Shrink Pic takes care of shrinking them. The result is you can drop huge photos into your email but the small converted ones will get sent instead.

The list of supported applications is a little outdated on the website. But, it works well on known browsers like Google Chrome, Firefox, IE, etc. Although it did not seem to work with Windows Live Mail. Compatible with Windows XP, Vista and 7.

TinyPNG

It is the probably best application for image optimization online. As the name shows that it can optimize only PNG file but it works both for PNG and JPG. It also has a lovely interface. Just drag and drop facility. You have to just upload the images only.

TinyPNG

Once uploaded, TinyPNG automatically compresses using a lossy method that maintains the perfect balance between quality and file size reduction. Files can be downloaded individually, as a single ZIP file, or moved to your Dropbox account.

But you can upload a maximum of 20 images at all with a size of 5MB each. If you want more from the tool then you have to go for its Pro version.

Picture Resizer

You may find when you have a look at Picture Resizer that the tool sounds some strange. It is because its options are not controlled in a Window. Go to the website, enter some options in the wizard for how to process the images.

Whole folders can then be dropped onto the file is an icon and they will be converted automatically. Double-clicking the executable will show a small window where you can enable a right-click context menu entry.

It has a four-step wizard that can assist you in setting up each batch conversion. With Free Picture Resizer you can resize and optimize images easily. You can use the wizard to help or you can manually adjust your own settings.

It allows you to set custom contrast, hue, saturation, and luminance levels, and you can apply various filters to achieve your desired result. Overall, Free Picture Resizer is a top tool for making small adjustments to individual photos or batches of images.

It is relatively lightweight and has a small footprint. That being said, although Free Picture Resizer is both functional and intuitive, the app’s interface does look a tad dated.

Something else it is good at is running from the command line with an extensive number of parameters. And this makes this program an indispensable tool for resizing from within batch files and scripts. As it is a small executable of 400K, you can make a copy of it.

Create a number of your own presets and simply drop your files onto the different icons to perform different resizing or compression tasks. Sadly Picture Resizer can only process JPG files. Works on Windows 2000 to 7 and has a separate 64-bit version.

CloudConvert– Batch Convert

CloudConvert is an incredible tool for any kind of file conversion. You have to connect your cloud account and pick files that way. No uploads allowed. But it supports dozens of image inputs and outputs so it is well worth it.

The best part of Fotosizer is that it has a renaming system. This is the advanced feature of the Fotosizer. If you want to rename your out files than you can do it easily with FotoSizer.

Resize Pic Online

It is another drag and drop tool for online image resize. You may find the application restrictive. You can bulk resize up to 10 images at once, size should not be more than 15 MB per image. And neither width nor height can exceed 6000 pixels on any image.

The site is available in Russian and English too, in case that matters to you. Upload your images, select a width between 30px and 1500px. After that select a quality between Low, Medium, High, and Best. And then choose whether you want to convert to JPG, PNG, or keep the original format.

You can also change the electronic size of your files. After you press “Change size” you will see a list of the images with all their dimensions. You can change the quality of the image from high to medium. This change will affect the image size. If you prefer to keep the image as high quality then in “settings” you can keep the high quality and change the dimensions until you are satisfied.

EasyImage Sizer

It is similar to FastStone Photo Resizer. It has limited features. If you are not looking for a high feature application then you can go for this. The odd thing is only the compression level and output location are visible when you first run the program.

The program used to batch compress, resize and rename Images. EasyImageSizer can reduce the file size of most Photos because it uses a better compression than most Photo Cameras. Additional you can reduce the file size by reducing quality. Image transformation is also 

The extra options like resize, rotate, rename, overlays and Exit need to be turned on by going to the Plugins menu or More Functions button. Its conversion speed is pretty fast and there are 10 output image formats you can convert to. Works with Windows XP, Vista and 7.

ConverSeen– Batch Convert

It is an open-source application and the huge amount of image file formats supported makes it very useful. Converseen supports more than 100 image formats. It is easy to use and fast in speed as well. You can easily resize your images.

One thing it does lack though is the option to simply add a folder full of images, the image files themselves have to be added. Standard options are there to resize the images and you can also alter the DPI of them as well.

Compression level settings are accessed via the “Images Settings” button, and another useful option is the ability to replace a transparent background with a specified color.

It also includes its own file browser in addition to the standard drag and drop.
