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.

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
Step 2 The first file is automatically compressed, and you'll see a download button - click that to save the file locally
Step 3 If you need to change the compression setting, use the slider and then hit the Compress button to compress again - you can also add additional images before you do this
Free to use, including bulk image optimization
Simple, user-friendly interface
Good compression level - reasonable compression quality

Doesn't always work well with very large files
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
Step 3 On the final page, you'll see a preview of the compressed image along with a toolbar with image editing options - click the Save icon on the extreme right side of the toolbar to download the compressed JPEG
Popular tool used by millions on social media and the web
A wide selection of other image and video tools
No way to increase the file size limit
No batch JPEG optimization
4. Image Optimizer
Another great free image optimization website is simply called Image Optimizer. There's also a downloadable JPEG optimizer package that you can use on your Windows desktop either for free or with a perpetual license that costs about GBP 29.00 or approx. USD 40. The online service is pretty good, too, with options to choose specific output image dimensions and compression quality.

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.
Steps to Optimize JPEG with PDFelement for Windows
Step 1 Create a PDF from the image file just by dropping the JPEG onto the PDFelement desktop icon or directly into the product interface - you can also use the Create PDF option on the home page and open the JPG as a PDF
Tip: You can also open several JPEG files using the Batch Process in the Tool section.
Step 2 For single-file operations, click the Compress PDF option in the Tool section and set the compression quality
Step 3 Click Apply and then use Convert → To Image to export the file as JPEG
Step 4 Click Apply after inputting the settings, then save the optimized PDF file to your desktop
7. PDFelement for Mac
Mac users can install the macOS version of PDFelement for Mac, which supports the latest macOS Big Sur as well as older macOS versions. The compression quality is equally astounding, and you also get access to numerous other tools for creating, editing, combining, annotating, protecting, filling, OCR-ing, and other PDF tasks. Images can instantly be converted to PDF to manipulation, after which you can export it as a JPEG file once again.
Steps to Use the JPEG Compressor to 50KB in PDFelement for Mac
Step 1 Click the File option in the main menu and go to New, then select PDF from File
Step 2 Selecting your JPEG source image in Finder will automatically convert it to PDF and display it in a new PDFelement tab
Step 3 To use the compression tool, go to File → Save As Other → Compress
Step 4 Select the compression quality and click Save As
Step 5 From its Finder location, which will be displayed on your Mac monitor, drag the compressed PDF back into the PDFelement interface and open it
Step 6 To export the PDF as JPEG, use this command flow: File → Export to → Image → JPEG
Your JPEG will now have the same compression quality as the optimized PDF file, and you'll see that the resulting file size is much smaller than the original image.

8. PDFelement for iOS
PDFelement for iPhone and iPad allows you to directly import files from your Photos app as PDFs. You can then compress these PDFs and take a JPEG output at the end. The iOS app comes with several other useful features such as PDF editing, file annotation, PDF security, and more.
