You can use any image in your gallery or even scan an image directly in the app! The process is a little different as you have to convert the image to a PDF first, compress it, and then use the “Convert from PDF” tool to save it back as a JPG.

You can also convert your JPEG on your phone with the Smallpdf Mobile App. If you have other image file types, such as PNG or BMP, you can also upload them to the tool, reduce the image’s size, and download back as a JPEG image. Change pixel size, or change image aspect ratio by adjusting horizontal and vertical percentages. On the left toolbar, find 'Resize' and click to open our photo size reducer. Then click 'Open Image' to upload your picture or directly drag it to the editing area. This is a pro feature though, but you can give it a try with our 7-day free trial. Click the 'Reduce Image Size Now' button on this page to open our photo editing tool. If the file size is still too large, you can always try the “Strong compression” option. Once you upload an image to our online tool, we’ll extract it to PDF format, compress the file, and then convert it back to JPEG format.Įven after we convert it to a PDF, on the result page, you can already see the compression rate and a much smaller image size.
