JPG images are popular as these images are lightweight, thanks to the compressed format. Users can store and share JPGs with ease.
However, if you're struggling with a very big JPG file, there are always tools—like ours!—to help you reduce JPG file size online, for free.
How to Reduce JPG File Size for Free Online
Go to the JPG Size Reducer.
Upload your JPG and convert it to PDF.
Click ‘Compress’ on the result page.
This tool will cut down the size of your JPEG file.
Then, click ‘to JPG’ to revert the file back to JPG.

Easy and effective JPG file size reducer
To elaborate, Smallpdf can compress PDFs, and also convert JPG to and from PDF. Combining these tools you can easily accomplish this task.
Maximum Compression
The compression level has been tested and fully optimized, to reduce the size of your JPG as much as possible, without being a detriment to the image quality.
We will do the math for you, and the compression rate (in percentage) will be displayed on the result page, post-compression - for you to analyze. Although we cannot set how much you can cut down with our JPG size reducer, we’ve been hitting the marks for the last five years, for over 20 million monthly users. Do check it out for yourself!
Compress Different Kinds of Images with a Batch Option
Images can get quite bulky, depending on the source of origin. Regular photos taken from your smartphone can go up to 2-3 MB, making it a hassle to store or share in large batches.
With our tools, you don't have to handle each file individually either. You can use our image compressor to handle individual files or batches. Just add the files to the PDF compressor in their original image format. Once they're converted to PDF and compressed, you can turn them back into JPGs in the next step.
How to Use the Online Image Size Compressor
- Open the Image Compressor page.
- Drag and drop your image into the toolbox.
- Click ‘Basic Compression’ and then ‘Choose Option’ to begin.
- On the following page, click ‘to JPG.’
- Choose ‘Convert Entire Pages.’
- And you’re set. Download your new and compact image.
Other Image Optimizers
After you decrease the file size, there are several other tools that you can use to enhance your PDF documents, including:
-
Edit - annotate images in PDF format.

Split - upload images can be divided if needed.

Scanned JPG Images
If the document you used is a scanned document in JPG format, and you wish to edit it further, you can convert it to PDF, then to Word. OCR has been enabled to ensure that we convert scanned files to an editable format for you, for ease of editing.

The file size limitation is 5GB per file, and you can freely use our online platform up to twice an hour! We believe that you don’t truly experience a product before testing them, so why not head over to our JPG size reducer or one of our other 20 tools to check it out for yourself? :)
