How to Reduce the Size of a JPEG Image Online and on Desktop

A JPEG optimizer is a tool or service that takes an image and downsamples it to a lower resolution in order to reduce the file size. Raw files taken from camera outputs are typically in high resolution. This is okay when actually using the file to make a large print such as a billboard or any type of outside advertisement; however, when dealing with mockup designs, these images need to be sent back and forth between the designer, the project manager, the client, and other stakeholders. In such instances, smaller file sizes are preferred for the sake of sharing and collaboration.

Once you learn how to reduce the size of a JPEG file, you can easily send or upload them anywhere without worrying about the time delay, size limitations, Internet interruptions, and other issues. Let's begin with a powerful set of tools to reduce JPEG size online before moving on to offline options.

Part 1: People Always Ask (FAQs)

Q1: Does optimizing photos reduce quality?

Yes, it usually does, since lossy compression is typically used by JPEG reducer applications and web services. However, that's not necessarily a bad thing because your output file will likely remain good enough for web use, except on very large screens or when cast to TVs with 4K and 8K support. For the most part, however, lower-resolution JPEGs are preferred for online use because they're easier to download and won't slow down the web page that contains them.

Q2: JPEG Optimizer Online vs. Offline JPEG Optimizer - the better choice?

There are advantages to using both types of JPEG optimizer methods. Online is convenient and can be done on any modern browser on a connected device. However, it's less secure and you'll need a pretty fast connection with lots of data allowance. Offline is great for security as well as handling large files or multiple image optimization tasks. On the flip side, offline tools use more local resources, which means you may not be able to do other work when performing a large JPEG file reducer operation.

Part 2: Best Online JPEG Optimizer Tools for Web Users

1. Wondershare HiPDF JPEG Optimizer

HiPDF is one of the top-rated online PDF platforms offering a plethora of handy tools for editing, compressing, protecting, organizing, form-filling, electronic signing, and OCR-converting PDF files, as well as tools to compress and manage JPEG and other image workflows. Each tool lives on its own unique URL, and the HiPDF site structure gives you a clear navigation path to find any tool you need. The compression quality leaves nothing to be desired - it's easy to use, offers various compression quality options, and can handle bulk processing if you have a subscription, which starts at a very affordable $6 a month on an annual plan or $42 yearly. Single-file processing is free, with certain limits.

Steps to Use the HiPDF JPEG Size Reducer Function

Step 1 Upload the Image to the HiPDF Compress Image webpage with a drag-and-drop motion or by clicking Choose File

2. 11zon JPG Compressor

This free utility can be used as a JPEG compressor to 50kb or less. The interface is very simple but there are several additional tools for compressing other file types such as PDF, editing JPEGs (crop, resize, etc.), and converting files to and from image formats. The compression quality is pretty good, and you can add more files to the queue after you've uploaded the first one.

How to Use the TinyPNG Image Compressor

Step 1 Upload the image file to the appropriate 11zon JPEG Optimizer by dragging and dropping it from its folder location

3. EZGIF JPG Size Reducer

EZGIF is a popular free GIF maker online that also comes with several other image modules such as adding effects, image cropping, adding text, and so on. The JPEG optimizer module, in particular, is pretty useful because it has a generous limit of 50MB. But that also means it won't accept very large high-resolution files. Nevertheless, it does offer a lossless JPEG compression method that only strips the metadata and similar markers such as thumbnails without affecting the quality of the image. In such cases, it's useful to note that you won't achieve a very high compression level.

Steps to Use the EZGIF JPEG Optimizer Online

Step 1 Upload your file in the EZGIF for JPEG optimization

Step 2 Click the Optimize Image button on the next page after changing any compression settings you want to

Part 3: Offline JPEG Optimizer Solutions

PDFelement is a versatile PDF tool with a built-in compression feature that you can utilize using a small workaround. Since it primarily handles PDF workflows, you'll need to upload the image files, which are then converted to PDF before the compression is applied. The output can be taken as JPEG once again after optimization. Here's a look at three versions of the software for Windows, Mac, and iOS.

6. PDFelement for Windows

Wondershare PDFelement - PDF Editor comes with a full suite of PDF and document management tools such as a PDF editor and annotator, compressor, file converter, password security, forms manager, file and page organizer, and more. The compression quality is among the best in the industry, but what makes the software popular is the intuitive layout and easy operational flow for all PDF tasks, no matter whether it's a simple text edit job or a complex batch conversion.
