ImageCompressly

Free browser-based JPEG tool

Free JPG Compressor

Reduce the file size of JPG and JPEG photos without sending them to a server. Choose a quality level, optionally limit the dimensions, and download each finished image or the complete batch.

This tool keeps JPG files as JPG. It does not convert them to another format, and an already efficient image may show little or no additional reduction.

Built for photographic images

Why compress JPG files?

JPEG is a practical format for photographs, gradients, and detailed scenes, but camera and export settings can leave more data in the file than you need.

Lighter photo uploads

Reduce the amount of image data you need to publish, attach, or transfer while keeping a usable visual result.

Quality you control

Start at the balanced 80% setting, then move higher for detail or lower when a smaller download matters more.

Optional photo resizing

Set a maximum width or height when the original dimensions are larger than the screen or placement where the photo will appear.

A practical JPEG workflow

How to compress a JPG online

JPG compression is lossy, so the useful goal is a sensible balance rather than a promise that every pixel stays identical. Preview important images after download before replacing an original.

  1. 01

    Add one or more JPG images

    Drop static .jpg or .jpeg files into the tool. Each file is validated and processed locally in your browser.

  2. 02

    Choose quality and dimensions

    Use 80% as a starting point. Enable resizing only when the source dimensions exceed what your website, email, or platform needs.

  3. 03

    Compare the result

    Review the original and compressed sizes shown for every image, then download files individually or together as a ZIP.

Useful JPG starting points

Everyday photos

Start around 80%

A balanced first pass for ordinary website photography, social posts, and email attachments.

Detail matters

Try 85–90%

Use a higher setting for portfolios, product close-ups, or images with fine texture, then check the output visually.

Small download first

Try 60–75%

A more aggressive range for previews and low-priority images where some extra loss is acceptable.

Where smaller JPEGs help

JPG compression is most useful when a photo is visually important but the original export is heavier or larger than its destination requires.

Product and blog photos

Prepare photographic content for cards, articles, listings, and galleries without uploading the source to ImageCompressly.

Email attachments

Make a batch of camera photos more manageable before adding them to a message.

Portfolio previews

Create lighter review copies while keeping your full-resolution originals stored separately.

Frequently asked questions

Straight answers about compressing static JPG and JPEG files.

Are JPG and JPEG the same format?

Yes. The two file extensions refer to the same image format, and ImageCompressly accepts both .jpg and .jpeg files.

Does JPG compression reduce image quality?

JPG compression is lossy and can remove visual detail. At moderate settings the difference may be difficult to notice, but you should inspect important results before publishing them.

Why did my JPG barely get smaller?

The image may already be well optimized or saved at a similar quality level. ImageCompressly keeps the original when a new encode would be larger and resizing is not required.

Can I resize a JPG while compressing it?

Yes. Open Advanced resize settings and set a maximum width or height. The tool never scales an image up.
