Easy and effective JPG file size reducer

To elaborate, Smallpdf can compress PDFs and also convert JPGs to and from PDF. So, in order to reduce the size of your JPG, you just need to combine these tools, and you’re good to go.

Maximum Compression


The compression level has been tested and fully optimized to reduce the size of your JPG as much as possible without negatively affecting the image quality.

We’ll 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 can’t set how much you can cut down with our JPG size reducer, we’ve been hitting the mark for the last five years with millions of 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 or 3 MB, making it a hassle to store or share. A picture taken with a professional camera can easily be a hundred times as large, so you can imagine why people may want to take the size down a notch.

With our tools, you don’t have to handle each file individually. 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

  1. Open the Image Compressor page.
  2. Drag and drop your image into the toolbox.
  3. Choose “Basic Compression.”
  4. Click “Export As” and choose “Image (.jpg).”
  5. Choose “Convert Entire Pages.”
  6. All set! Download your new compact images.

Other Image Optimizers


After you decrease the file size, there are several other tools you can use to enhance your PDF documents, including:

  • Edit - Annotate images in PDF format.
  • Split - Images can be divided into separate documents.
  • eSign - Did you scan a contract? Sign it digitally with us.
  • Rotate - Spin pages around with this online tool.
  • Converter - Change JPG to PDF, Word, PPT, or Excel.

Scanned JPG Images


If the document you used is a scan in JPG format and you want to edit it further, you can convert it to PDF, then to Word. Smallpdf uses sophisticated Optical Character Recognition (OCR) software, which converts scanned files to an editable format for you, making it easy to edit pretty much anything. You’ll need a Pro account to use this feature—you can try it out for free with our 7-day free trial.

This Is All Free?


Smallpdf is free to use up to a certain number of times per day with a file size limitation of 5GB per file! We believe you don’t truly experience a product until you test it, so why not head over to our JPG size reducer or one of our other 20 tools to check it out for yourself?

Happy compressing!
