Compress JPG
Compression changes the way the JPEG image is encoded to reduce the file size. The pixel dimensions can remain exactly the same.
- • Reduces file size
- • Can preserve original width and height
- • Controlled through JPEG quality
Compress JPG and JPEG images online with adjustable quality. Reduce JPG file size for websites, email, uploads, and storage while keeping a good balance of image quality and file size.
JPG & JPEG Compressor
Reduce the file size of JPG and JPEG images with adjustable compression quality. Select a photo, choose a quality level, preview the result, and download the smaller JPG.
JPG compression is useful when an image is too large for a website, email attachment, online form, upload, or everyday sharing. You can reduce the file size while keeping the original image dimensions when resizing is not required.
JPG and JPEG are the same format. The difference is only the filename extension: .jpg and .jpeg both refer to JPEG images.
Need a specific file size? If your requirement is something like 20 KB or 100 KB, use a target-size compressor instead of relying only on a quality setting.
These are related but different ways to make an image more suitable for an upload or website.
Compression changes the way the JPEG image is encoded to reduce the file size. The pixel dimensions can remain exactly the same.
Resizing changes the pixel dimensions of the image, such as reducing a 4000 × 3000 photo to 1600 × 1200.
If a website requires both a maximum file size and specific image dimensions, you may need to resize the JPG first and then compress it.
A smaller JPEG is easier to upload, send, publish, and store.
Reduce the amount of data sent when uploading photos.
Smaller files are generally easier to send and share.
Reduce image payloads for pages that use JPEG photographs.
Keep photo collections smaller without keeping unnecessarily large JPEG files.
A focused workflow for reducing JPEG photo file sizes.
Designed specifically for the JPEG format and its common .jpg and .jpeg extensions.
Choose how aggressively the JPEG should be compressed instead of using one fixed setting.
Review the compressed result before saving the optimized image.
The compression workflow is designed to run directly in your browser.
Compression can reduce file size without changing the image width and height.
Download the compressed JPG as soon as the optimized result is ready.
Use the compressor on phones, tablets, and desktop devices.
Suitable for website images, email attachments, online forms, sharing, and storage.
Use quality values as a starting point rather than expecting a fixed percentage reduction.
| Quality | Compression | Typical Use |
|---|---|---|
| 90–100 | Light compression | When preserving more detail is important |
| 75–90 | Balanced compression | Websites, blogs, sharing, and everyday photos |
| 60–75 | Stronger compression | Smaller uploads and file-size-conscious use |
| Below 60 | Aggressive compression | Situations where a much smaller file is more important than image quality |
Important: JPEG quality values do not correspond to a guaranteed percentage reduction in file size. The final size depends on the image, dimensions, existing compression, and the encoder.
Reduce a JPEG photo in a few simple steps.
Choose the photo you want to make smaller from your device.
Adjust the quality level to control the balance between image detail and file size.
Generate the optimized JPG using the selected compression setting.
Preview the compressed image and check that the quality is suitable.
Save the optimized image to your device when you are satisfied with the result.
JPEG compression is useful whenever a smaller photo file is more convenient.
A convenient workflow for processing photos from your device.
The compressor is designed around browser-based image processing. When compression is performed entirely on the client, your JPG does not need to be uploaded to a remote server just to create the compressed image.
Your actual implementation should be the source of truth for this statement. Do not describe the tool as fully local if any part of the image-processing workflow sends the file to a server.
Choose another image compression workflow when you need a different target file size or compression format.
Common questions about JPG and JPEG file-size reduction.
A JPG compressor reduces the file size of a JPG or JPEG image by re-encoding the image with a selected compression quality. The pixel dimensions can remain unchanged.
Yes. JPG and JPEG refer to the same JPEG image format. The .jpg and .jpeg extensions are simply different filename conventions.
Yes. JPG compression can reduce the file size while keeping the original pixel dimensions unchanged. Resizing is a separate operation that changes the image width and height.
JPEG compression is generally lossy, so there is no guarantee of zero quality loss. Moderate compression can often reduce file size while keeping the image looking very similar to the original.
A medium-to-high quality setting is a good starting point for most photographs. If the image is going on a website or needs to meet a file-size limit, you can try a lower setting and compare the preview.
There is no fixed percentage. The result depends on the original dimensions, image detail, existing JPEG compression, encoder, and selected quality. Highly detailed or already-compressed images may behave differently from other photos.
Not necessarily. Compression and resizing are different operations. Compression changes how the image is encoded, while resizing changes its pixel dimensions.
Yes. Smaller JPEG files can reduce the amount of image data that a webpage needs to download. Choose a quality level that keeps the image visually suitable for your page.
Yes. Compressing a JPG can make an attachment or upload smaller and can help when a website or service has file-size limits.
A quality-based JPG compressor does not necessarily produce an exact target size. If you need to meet a specific file-size requirement, use a target-size compression tool designed for limits such as 20 KB or 100 KB.
This tool is designed to process images directly in the browser. If the current implementation performs the compression entirely client-side, the selected image does not need to be uploaded to a remote server for the compression operation.
Yes. The interface is responsive and can be used on modern phones, tablets, and desktop computers.
Yes. The JPG compressor is available to use without a paid plan.
Select a JPG or JPEG photo, adjust the compression quality, compare the result, and download a smaller image. If you need a specific target such as 20 KB or 100 KB, use the corresponding target-size compressor instead.
